Why is the machine-added graphite plate dominant in the field of graphite bipolar plates?

Jun 27,2022

According to the research data of the Institute of Hydrogen and Electricity (GGII) of High Industry, Production and Research, the shipment scale of Chinese enterprises hydrogen fuel cell graphite bipolar plate reached 0.294 billion billion yuan in 2021, an increase of 49.24 percent over the previous year. Among them, the shipment scale of machine-added graphite plate was 0.257 billion yuan, up 48.55 over the previous year. In 2021, the proportion of CNC process shipments in the domestic graphite bipolar plate is more than 85%. This is because the machine plus graphite plate itself has advantages, in the graphite bipolar plate cost-effective trend, the production efficiency of the machine plus graphite plate in the increase, the price is down. The fuel cell bipolar plate is the "skeleton" in the stack, which is laminated with the membrane electrode and assembled into the stack, and plays the role of supporting, collecting current and distributing gas in the fuel cell. The importance is self-evident. Currently, fuel cell bipolar plates on the market are classified into graphite (composite) bipolar plates, metal bipolar plates, and the like. Among them, graphite bipolar plate technology has become more mature and occupies a dominant position in market applications. Graphite bipolar plates are divided into machine-added graphite plates (CNC machining process) and molded graphite plates according to different processing techniques. These two technical routes have their own characteristics. The advantage of machine-added graphite plate is that machine-added ink plate itself has the advantages of good conductivity, long service life, high power density, strong stability and excellent product performance. At present, the fuel cell industry is in the demonstration operation stage, and the market purchase volume of bipolar plate is not stable, and most of them are customized products. In this case, downstream enterprises are willing to choose machine-added graphite plate with good processing flexibility and strong adaptability for development and testing. The advantages of the molded graphite plate are short production time and high efficiency, which is more in line with the requirements of commercial mass production of fuel cells. However, compared with the machine-added graphite plate, this technical route is more difficult in process control and quality control, and the initial investment is more. Most fuel cell companies are actively expanding the diversified applications of fuel cells, such as hydrogen forklifts, cogeneration, drones, two-wheelers, etc. The applications in this part of the market are mainly machine-based graphite plates. The rise of diversified development momentum has expanded the market space of machine-added graphite plate. There are not many enterprises in China that can supply molded graphite plate products in batches, and downstream users have more opportunities to select machine-added graphite plates than molded graphite plates. In terms of graphite bipolar plates, it is inevitable that machine-added graphite plates occupy most of the market share.

Haydale functionalized graphene conductive reinforcing filler

Haydale functionalized graphene conductive reinforcing filler

Jun 29,2022

Every once in a while, there will be new scientific breakthroughs to change the world. According to an information disclosed by the British Haydale Company, a functionalized graphene conductive reinforcing filler developed by Haydale Company is currently a patented technology. The conductive reinforcing filler is added to the functionalized nanoparticles, and finally used in the preparation of prepreg, thereby forming a new type of functional integrated component, the technical director of the Haydale said that the functionalized graphene conductive reinforcement filler of this patented technology greatly enhances the stealth capability of the aircraft, or will bring revolutionary changes in the research process of stealth technology or wave-absorbing materials. Radar stealth is mainly to reduce the radar cross section (RCS) of the aircraft. The main measures are usually: a unique aerodynamic shape design, that is, through a special shape design to control the direction of the radar echo; the use of absorbing materials and absorbing structures that can absorb radar waves, so that the scattering field is weakened, which can not form an effective echo signal. For example, the United States F-117A stealth fighter. In the research process of stealth technology, absorbing materials and absorbing structures have become the biggest contribution point of stealth technology research. Absorbing materials can also be divided into two types from the material composition, one is a coated absorbing material, and the other is a structural absorbing stealth material. The coated wave absorbing material is made by adding wave absorbing agent to resin base or rubber base. This kind of wave-absorbing material construction, can be used brushing or spraying method of construction, can be applied to complex curved surface, such as wave-absorbing paint/stealth paint. However, this coating material has the problem of weather resistance, because it adheres to the surface of the aircraft, the surface adhesion gradually decreases with the change of service life and climate, and even falls off. At the same time, it also faces problems such as follow-up maintenance and repair. Structural wave-absorbing materials are usually made of resin/fiber-reinforced composites as carriers and added with absorbents. It is a kind of multi-functional composite material, which can not only carry the structural parts, but also have the advantages of light weight and high strength of composite materials, and can absorb or pass through electromagnetic waves well. It has become an important development direction of stealth materials. At present, some foreign military aircraft and missiles have adopted structural wave-absorbing materials, such as the horizontal stabilizer of SRAM missile, the edge of the A- 12 fuselage, the leading edge of the wing and the lift aileron, the fairing of the F-111 aircraft, the inlet of the Harrier-Ⅱ aircraft jointly developed by B- 1B, the United States and Britain, and the air-ship bomb ASM-1 and the wing of the ground-ship bomb SSM-1 developed by Mitsubishi Heavy Industries of Japan, in the picture, the UAV is jointly developed by the University of Central Lancashire and Haydale to use nano-graphene wave-absorbing carbon fiber prepreg as the "coat" of the UAV ". The rapid development of composite materials provides a guarantee for the development of structural absorbing materials. The new thermoplastic PEEK, PES, PPS and thermosetting epoxy resin, bismaleimide, polyimide, polyetherimide and isocyanate all have good dielectric properties, and the composite materials made of them have good radar transmission and transmission. In recent years, foreign countries have made a lot of improvement work on carbon fiber, such as changing the cross-sectional shape and size of carbon fiber, surface treatment of carbon fiber surface, so as to improve the electromagnetic properties of carbon fiber, etc., for wave-absorbing structure. The Haydale developed functionalized graphene wave-absorbing stealth filler can be used for the fusion of composite materials and resins without increasing the weight, endowing the body material with radar transmission and transmission, and forming a structural wave-absorbing material. Haydale, after years of research and development, Haydale functionalized graphene conductive reinforcing filler has applied for a patent for a process that allows graphene to be functionalized through a plasma reactor-even if it can be combined with other materials, thereby taking advantage of the properties of graphene and other nanomaterials to give ordinary materials the superpower of graphene.

Review of Covalent Chemical Control Methods for Graphene Oxide

Review of Covalent Chemical Control Methods for Graphene Oxide

Jun 29,2022

Graphene has attracted extensive research interest in many fields due to its unique physical and chemical properties. However, its low solubility in most organic solvents and water, as well as its tendency to aggregate, prevent full utilization of its properties. Graphene oxide (GO) is an alternative material with high diffusivity in polar solvents. Graphene oxide contains rich oxygen-containing groups, mainly epoxides and hydroxyls, which can be further chemically derivatized. However, due to the high reactivity of graphene oxide, several reactions may occur simultaneously, usually leading to runaway graphene oxide derivatives. Recently, a research team led by Professor Cécilia Ménard-Moyon from the University of Strasbourg in France published a review article on the Nature Reviews Physics on the topic of Controlling covalent chemistry on graphene oxide, systematically discussing the chemical reactivity of graphene oxide and the problems that hinder the precise control of its functionalization, such as its instability, lack of clear chemical structure and the presence of impurities. The article focuses on the selective derivatization strategy of oxygen-containing groups and C = C bonds, as well as the challenge of unambiguously characterizing the final structure. This review not only briefly reviews the application of graphene oxide materials, links its chemistry and nanostructure with the required physical properties and functions, but also points out the future direction of improving the chemical control of graphene oxide. For more than 15 years, graphene has attracted interest in various fields due to its unique optical, electrical, thermal and mechanical properties. However, the low dispersibility of graphene in most organic solvents and water and its aggregation limit its processability. In addition, the sp2 basal plane of graphene is relatively inert, which inhibits its covalent functionalization, thus limiting its application range. In contrast, the oxidized form of graphene-graphene oxide (graphene oxide)-is highly dispersible in many solvents, and the rich oxygen-containing moiety provides a handle for extensive chemical derivatization. These properties facilitate processing and make the production of graphene oxide materials inexpensive and scalable. Graphene oxide is composed of flexible two-dimensional graphite flakes of atomic thickness with lateral dimensions on the nanometer to micrometer scale. The surface of graphene oxide is modified by oxygen-containing groups: many epoxide and hydroxyl (-OH) moieties are mainly located on the basal plane, while some carboxyl (-COOH) groups are present at the edges. It must be understood that graphene oxide is not a single compound, but a heterogeneous class of materials. The physical and chemical properties and corresponding applications of graphene oxide are defined by its composition and structure at different scales (Figure 1a). The properties depend on chemical details (e. g., the level of oxidation, the proportion and location of oxygen-containing groups, and the number of remaining non-oxygen groups), the density of defects and nanopores, and the distribution and aggregation of functional groups. The properties of the graphene oxide can be further modified by changing the microstructure, I .e., the size distribution and relative arrangement of the flakes (e. g., liquid suspended flakes, hydrogels, or laminates). This layered structure determines the optical and electrical properties of graphene oxide-based materials, as well as liquid, ion and gas transport properties. The chemical modification of graphene oxide provides an opportunity to controllably change the properties of related materials, improving their performance in many applications, including in environmental and energy-related fields, polymer composites, sensing, filtration, catalysis and Nanopharmaceuticals and other fields. However, since graphene oxide is unstable under heat and in the presence of strong bases, functionalization must be carried out under neutral and mild conditions to avoid dehydration and reduction of graphene oxide. Due to the relatively high reactivity of oxygen-containing groups in graphene oxide, multiple reactions may occur simultaneously during the functionalization process, which may lead to side reactions and synthesis of materials with unclear composition. Thus, controlled functionalization of graphene oxide requires a synthetic strategy and accurate characterization of functionalized materials requires technology. In this review, the article outlines the chemical reactivity of graphene oxide and discusses the factors that hinder the precise control of graphene oxide functionalization; these include the lack of a clear chemical structure of graphene oxide macromolecules, its thermal instability, Incompatibility with strong bases and possible impurities. The article details the selective covalent derivatization of different oxygen-containing groups and C = C bonds, focusing on facilitating the understanding of reactivity rather than mechanical details. The discussion in this article is limited to covalent chemistry because it provides graphene oxide conjugates that are more stable than graphene oxide conjugates produced by non-covalent interactions. Failure to grasp the heterogeneity of Go material often leads to erroneous conclusions and erroneous communication in the literature. Finally, the structure-function relationship of functionalized graphene oxide is discussed in the application examples of environment and energy related fields. Graphene oxide has been developed for various applications in different fields, from sensing, catalysis and composite materials to environmental science, energy and biomedicine. The chemical composition of graphene oxide affects its properties, and the covalent grafting of molecules on its surface represents a valuable strategy to adjust and improve the properties of materials to suit different applications. The article introduces examples of the use of functionalized graphene oxide in most application fields (ie, environmental and energy-related fields), and focuses on the study of functionalization of graphene oxide under mild conditions and high chemical selectivity. Environmental Applications In order to improve sustainability and energy efficiency, investigations have been conducted on the environmental application of graphene oxide in drinking water purification; membrane separation processes, including seawater desalination; and the collection of osmotic energy. The function and performance of graphene oxide-based materials in environmental applications, especially in the development of separation membranes, depends not only on the chemical properties of graphene oxide, but also on its hierarchical structure. A separation membrane made of graphene oxide consists of horizontally aligned graphene oxide flakes and nanosheets, stacked into a layered structure that is stable in water. Once hydrated, the film swells and the nature of the functional groups determines the interlayer distance between the lamellae. As the solution permeates between the sheets, it flows in a percolation path between the separated functional groups along the graphene oxide basal plane until it snakes through the membrane. The frictionless surface of the pristine graphene region facilitates ultrafast transport of water. The selectivity of the membrane is based on the size and dewaterability of the hydrated ion (determined by the interlayer distance), charge selectivity (through protonatable functional groups) and chemical affinity. For the accepted pressure-driven desalination (reverse osmosis) technology, graphene oxide membranes have not yet reached the performance of traditional thin-film composite membranes, mainly because of the poor ion/water selectivity of graphene oxide. Attempts to reduce the interlayer distance between graphene oxide flakes by physical confinement and chemical cross-linking have not significantly improved reverse osmosis performance. However, due to its high charge selectivity, graphene oxide membranes may still dominate in two emerging technologies: desalination by electrodialysis and energy harvesting by reverse electrodialysis. Other prominent applications of graphene oxide membranes are organic solvent separation and pervaporation, which is a membrane evaporation process that separates organic-water and organic-organic mixtures. Energy Applications Due to the increasing demand for energy, fuel cells have attracted great interest because they are an environmentally friendly and efficient alternative energy source suitable for many applications. There are numerous articles on the use of functionalized graphene oxide in energy-related applications. In the article, the authors highlight several examples where the functionalization of graphene oxide has been well controlled. Proton exchange membrane (PEM) fuel cells are usually made of polyelectrolytes, which convert chemical energy into electrical energy through an electrochemical reaction between hydrogen and oxygen, while producing water and heat. The performance of proton exchange membranes depends to a large extent on their proton transport capacity. Therefore, a lot of research work has been invested in the development of proton exchange membranes with high proton conductivity. In this regard, there are mainly two methods: modifying existing polyelectrolytes and proton exchange membranes with additives, or synthesizing new polyelectrolytes to design new proton exchange membranes. For example, graphene oxide functionalized with Nafion by an atom transfer radical addition reaction is used as an additive for Nafion-based composite proton exchange membranes for fuel cells. Compared with Nafion membrane, the composite shows higher proton conductivity. The improvement in performance is attributed to the aggregation of the sulfonic acid groups of the Nafion chains grafted onto graphene oxide, forming proton-conducting domains. As analyzed in this paper, the relatively low production cost of graphene oxide, its dispersibility in various solvents including water, and its tunable surface chemistry make graphene oxide an attractive building block for multifunctional materials. In many applications, maintaining the intrinsic properties of graphene oxide is critical. For example, the high density of oxygen-containing groups in graphene oxide leads to high water dispersibility and high proton conductivity and water retention. Therefore, the derivatization of graphene oxide must be well controlled to impart new properties, and the functionalized samples must be thoroughly characterized. These tasks are complicated because the chemical structure of graphene oxide has not been fully elucidated, and the level of defects and the ratio of different oxygen-containing groups may vary depending on the synthesis scheme and the source of the graphite. All structural models focus on the fact that the basal plane of graphene oxide is rich in epoxides and hydroxyl groups, which can be functionalized to adjust the properties of the material, while the carboxyl groups are only present in small amounts. Although great progress has been made in the functionalization of graphene oxide, the chemical properties of graphene oxide are not always well controlled and are not fully understood. The article points out that the reactivity of graphene oxide is determined by a complex set of factors, because the oxygen-containing groups are located in an abundant and unusual chemical environment, and significant in-plane distortion and strain in the crystal lattice will increase their reactivity. Due to the different oxygen-containing groups on the surface of graphene oxide and the high chemical reactivity of certain reagents, simultaneous reactions may occur to produce uncontrolled graphene oxide derivatives. The main purpose of this review is to clarify the chemical reactivity of graphene oxide and provide key and useful suggestions on how to promote its functionalization without reducing materials that will affect its performance. The article emphasizes the importance of chemoselective reactions, which allow one specific oxygen-containing group or C = C bond to be derivatized without affecting other moieties, thus providing the possibility for controlled multi-functionalization of graphene oxide. The simplest and most effective strategies involve epoxides and hydroxyls because of their abundance. In this review, the article mainly describes reactions that do not require thermal activation and proceed at room temperature. When functionalizing graphene oxide, it is important to use mild reaction conditions, particularly in terms of temperature and pH when needed, to avoid removal of labile oxygen-containing groups and degradation of the graphene oxide framework.

Preparation of Flexible Ferromagnetic Graphene Quartz Fiber Fabric with Super-large Size and Ultra-wideband Strong Electromagnetic Shielding Properties

Preparation of Flexible Ferromagnetic Graphene Quartz Fiber Fabric with Super-large Size and Ultra-wideband Strong Electromagnetic Shielding Properties

Jul 07,2022

Liu Zhongfan of Peking University and Beijing Graphene Research Institute-The research team has made important progress in the preparation and application of flexible graphene quartz fibers. The team reported for the first time the use of roll-to-roll chemical vapor deposition (CVD) technology to batch prepare large-area, lightweight, flexible, ferromagnetic graphene quartz fiber fabric (FGQF) with ultra-wideband strong electromagnetic shielding effectiveness. The relevant results are titled "Ultra-broadband strong electromagnetic interference shielding with ferromagnetic graphene Quartz fabric. In this work, an oversized flexible ferromagnetic graphene quartz fiber fabric (FGQF) was first prepared using a roll-to-roll CVD batch growth system. By precisely controlling the nitrogen doping type of graphene, the preparation of ferromagnetic graphene layers with high conductivity (3906 S · cm-1) and high magnetic response (saturation magnetization of 0.14 emu · g-1 at room temperature) was achieved (Figure 1a). At the same time, the special woven structure of FGQF fabric introduces additional multiple reflection and multi-channel absorption of electromagnetic waves into the material, which further enhances the electromagnetic shielding effectiveness of the material. The 1 mm thick FGQF exhibits a superior shielding effectiveness of 107 dB at an ultra-wide band of 1-18 GHz, while achieving high EMI shielding efficiency and a wide EMI immunity band (Figure 1c). Using the graphene roll-to-roll continuous CVD growth system independently developed by the team (Figure 1b), the large-scale preparation of FGQF was realized, with a single batch preparation size of up to 10 × 0.5 m2 (Figure 1d), which provides an important basis for the practical application of materials. Based on the high conductivity, ferromagnetism and special woven structure of FGQF, when the electromagnetic wave reaches the surface of the material, it interacts with the free carriers on the surface of graphene, and part of the electromagnetic wave is reflected. By optimizing the impedance matching at the air-material interface, the remaining electromagnetic waves will enter the inside of the FGQF, match with the FGQF conductive network, and produce multiple internal reflections in its woven structure. Therefore, the ferromagnetic graphene layer with high conductivity and high magnetic response can achieve effective absorption and attenuation of electromagnetic wave energy (Figure 2a). The shielding mechanism of single ferromagnetic graphene quartz fiber (about 7 μm in diameter) in FGQF fiber cloth is analyzed in detail. The electromagnetic wave is reflected multiple times in the adjacent fiber array, and the multilayer ferromagnetic graphene can efficiently absorb the reflected electromagnetic wave, further attenuate the electromagnetic wave energy, so as to obtain high electromagnetic shielding effectiveness.

GMG leads graphene aluminum ion battery innovation

GMG leads graphene aluminum ion battery innovation

Jul 25,2022

Australia's Graphene Manufacturing Group (GMG) announced that the trial production and testing plant for graphene aluminum-ion batteries has been put into operation, and button batteries, a potential competitor to lithium-ion batteries, have also been manufactured. Craig Nicol, Managing Director and CEO of GMG Group, said, "the commissioning of the battery pilot plant is an important milestone for GMG Group, which not only means that we can develop, manufacture and test our own G + Al button cells, but also promote the commercial development of G + Al batteries, cooperation with future customers, and further strengthen our expertise." The company does not mine graphite, but produces graphene by cracking methane. The company used a patented process to design a method to produce high-quality, low-cost, scalable, adjustable, non-polluting or low-polluting graphene. While the graphene produced by GMG can be used in multiple industries, the company's initial focus was on developing applications for energy saving and energy storage solutions, and its vision is now being realized through the pilot plant for the production of graphene-based aluminum-ion batteries. A potential competitor to lithium-ion batteries, this globally unique battery was developed by GMG Group, the University of Queensland Institute of Bioengineering and Nanotechnology and UniQuest companies and is now in production at scale. GMG Group's laboratory tests show that the G + Al battery energy storage technology has a higher energy density and higher power density than the current market-leading lithium-ion battery technology. The detailed technical parameters published by the company show that the power density of up to 7000 Wh/kg was confirmed by tests during 3000 cycles of experiments, including charging to full charge and discharging to almost complete loss of power at different charging rates. In addition, the test results show that the cycle rate during the test period is very high, and its charging rate is as high as 66 coulombs (ie, amps/s), and the performance degradation is negligible. In contrast, lithium-ion batteries have a charging rate of 600 to 100 cycles. Lower, performance is usually reduced to 60% of the original capacity. In the real world, this means that G + Al batteries have a longer lifespan and a shorter charging time. Professor Alan Rowan of the University of Queensland said, "Tests have shown that rechargeable graphene aluminum-ion batteries have a lifespan of three times that of current mainstream lithium-ion batteries, and the higher power density means that they can be charged 70 times faster. This battery can be charged multiple times without performance degradation, is easier to recycle, and reduces the possibility of harmful metals leaking into the environment." These parameters make graphene aluminum batteries a potential choice for electric vehicles and electronic devices, because battery life, charging time and durability are basically important factors to consider for all applications.
