Since this year, the lithium battery pack market has been enthusiastic about graphene materials, and many manufacturers and scientific research institutions are making more and more attempts to apply graphene as a new battery material. Graphene is a two-dimensional crystal composed of carbon atoms arranged in a hexagonal shape and connected to each other to form a carbon molecule. Its structure is very stable.

　　Zhejiang Alenian Nano Technology Co., Ltd. invested 160 million yuan in the construction of a graphene lithium-ion battery ternary cathode material construction project. The project covers an area of 40 acres. After the project is completed, it will have an annual production capacity of 6000T/a graphene lithium-ion battery cathode materials. Previously, Zhejiang University's Gao Ming team developed a new type of aluminum-graphene battery that can be charged in just a few seconds. It is still fully charged after 250,000 cycles of charging and discharging. It has also demonstrated heat resistance and frost resistance, and repeated bending does not affect its function. and other excellent properties, showing widespread application prospects.

　　So, will graphene be a breakthrough in the next generation of materials for lithium battery packs?

　　Graphene material characteristics:

　　Graphene has a unique two-dimensional structure, excellent performance and various potential application values. Graphene-based nanomaterials are an attractive electrode material for lithium-ion batteries, especially for high-energy-density and high-power-density batteries. The graphene battery is a new battery developed by utilizing the characteristics of lithium ions that shuttle rapidly and massively between the graphene surface and the electrode.

　　Coupled with the layout of graphene lithium-ion batteries by relevant manufacturers in the lithium battery industry chain, the emergence of graphene lithium-ion batteries may be accelerated.

　　Graphene is an important option for high energy density batteries

　　In the context of national policies leading the development of lithium battery packs towards high energy density, graphene materials are a good candidate for the next generation of battery materials. Graphene has always been considered a representative material among the new generation of materials. Graphene peeled from graphite is a thin film of carbon atoms, which is characterized by high physical and chemical stability. The material is 100 times more conductive than copper and more than 140 times faster than silicon. This is why graphene ball batteries charge five times faster than existing rechargeable batteries. With its excellent material properties, graphene is favored by research institutions and lithium battery pack companies.

　　New battery material “graphene balls”

　　The new battery material "graphene balls" have a charging capacity 45% higher than existing lithium-ion batteries and a charging speed that is more than five times faster. Researchers have discovered that after adding silica to the high-strength, highly conductive graphene material, graphene can be synthesized in large quantities. The synthesized graphene exhibits a three-dimensional shape like popcorn, so it is called "graphene ball" , using this graphene ball material as anode protective film and cathode material for lithium-ion batteries can increase charging capacity, shorten charging time, and ensure high-temperature stability.

　　Graphene new energy industrialization project

　　At the end of March this year, the graphene new energy industrialization project settled in Yinchuan Economic and Technological Development Zone plans to invest 8.5 billion yuan to implement projects with an annual output of 30,000 tons of graphene-modified ternary materials and 10,000 tons of graphene conductive slurry. 5 projects, after completion, can form a basic industrial chain of graphene energy storage materials in Yinchuan City, and form an annual output value of more than 15 billion yuan.

　　Disadvantages of graphene materials

　　Some scholars believe that graphene batteries may only exist in laboratories, and it is still relatively difficult to popularize them commercially. They believe that the reproducibility of graphene work is often poor, and the technology is seriously out of touch with practical goals.

　　Materials are one of the three pillars of modern civilization. The discovery of new materials and their cross-field applications play a vital role in the development of science and technology. The battery industry has evolved from traditional lithium batteries to later cobalt-lithium batteries, to today's high-nickel batteries. Graphene may be a breakthrough for the next generation of materials for lithium battery packs.

　　Do you guess, will graphene be the breakthrough for the next generation of materials for lithium battery packs? Is there any development prospect? This issue is left to you to discuss. Welcome to leave a message on the website message board and discuss with the editor.
