402030 battery

Is graphene a breakthrough for 402030 battery materials?

Since this year, the market has been enthusiastic about graphene materials, and many manufacturers and scientific research institutions have tried more and more to use graphene as a new battery material. He Shiguo, the project leader of Enlian Nano, once said that Enlian Nano's battery positive electrode material is the core technology of pure electric vehicle batteries. So, will graphene be a breakthrough for 402030 battery materials? Can it provide an additional solution option for the current problems encountered by lithium-ion batteries?

Graphene 402030 battery is emerging

Graphene has a unique two-dimensional structure, excellent performance and various potential application values. Graphene-based nanomaterials are a very attractive lithium-ion battery electrode material, especially for high energy density and high power density batteries. Graphene batteries are a new type of battery developed by using the characteristics of lithium ions moving rapidly and in large quantities between the graphene surface and the electrode.

Interestingly, in addition to Zhejiang Enlian Nanotechnology Co., Ltd. investing in the construction of a graphene base, Yulong Co., Ltd. recently issued an announcement to increase investment in graphene. It is reported that Yulong Co., Ltd. will increase its capital by RMB 300 million in Ningxia Hanyao Graphene Energy Storage Materials Technology Co., Ltd., mainly to accelerate the construction and production of the production line of Ningxia Hanyao lithium-ion battery graphene ternary positive electrode materials and conductive slurry projects, drive production capacity and release new business development.

The layout of graphene lithium-ion batteries by manufacturers related to the 402030 battery industry chain may accelerate the launch of graphene lithium-ion batteries.

Graphene is an important option for high-energy-density batteries

In the context of the development of lithium batteries towards high energy density led by national policies, graphene materials are a good candidate for next-generation battery materials. Graphene has always been considered a representative material among the new generation of materials. Graphene peeled from graphite is a thin carbon atomic film, which is characterized by high physical and chemical stability. The material is 100 times more conductive than copper; more than 140 times more conductive than silicon. This is also the reason why graphene ball batteries charge five times faster than existing rechargeable batteries. With its excellent material properties, graphene has been favored by research institutions and 402030 battery companies.

At the beginning of this year, it was learned from the website of the Ministry of Science and Technology that the Korean newspaper "Joongang Ilbo" reported that the research team of Samsung Electronics Institute of Advanced Technology successfully developed a new battery material "graphene ball", which has a 45% higher charging capacity than the existing lithium-ion battery and a charging speed of more than 5 times. Researchers found that after adding silicon dioxide to high-strength and high-conductivity graphene materials, a large amount of graphene can be synthesized. The synthesized graphene presents a three-dimensional shape like popcorn, so it is called "graphene ball". After using this graphene ball material for the anode protective film and cathode material of lithium-ion batteries, the charging capacity can be increased, the charging time can be shortened, and the high-temperature stability can also be guaranteed. South Korea plans to commercialize "graphene ball" lithium-ion batteries within five years.

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

Not long ago, the Massachusetts Institute of Technology in the United States successfully developed a flexible photovoltaic panel with a graphene nanolayer on the surface, which can greatly reduce the cost of manufacturing transparent deformable solar cells. This battery may be used in small digital devices such as night vision goggles and cameras.

Although graphene batteries have been favored by many manufacturers and investors, there are also voices of opposition. First of all, the cost and process complexity are high. Some scholars believe that graphene batteries may only exist in laboratories, and commercialization is still relatively difficult. Oak Ridge National Laboratory and Vorbeck, a well-known graphene industry manufacturer, have disclosed the research results of graphene. They believe that the repeatability of graphene work is often poor, and the technology is seriously out of touch with the practical goals. This phenomenon has been widely criticized by knowledgeable people in the scientific research community and the industrial community.

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 cobalt-lithium batteries, and now to high-nickel batteries. Graphene may be a breakthrough for the next generation of power batteries. The development of battery technology is also promoting the iteration of various electronic terminal products.
