On July 8, the world’s first graphene-basedButton lithium batteryThe product was released in Beijing. Experts believe that the successful development of this product has completely opened up the application of graphene in consumer electronic lithium batteries.3V lithium battery,High capacity lithium battery, the application space of lithium batteries in the field of power lithium batteries and energy storage.
The first graphene-based lithium-ion battery product was launched by Shanghai Carbon Source Huigu, a subsidiary of the listed company Dongxu Optoelectronics, and named "Gene King". The product has excellent performance and can work in the environment of -30 degrees Celsius to 80 degrees Celsius. The battery cycle life is up to about 3,500 times, and the charging efficiency is 24 times that of ordinary charging products.
In fact, the charging and discharging speed of lithium-ion batteries is determined by the transmission and deintercalation speed of lithium ions in the electrode. Graphene has excellent electronic and ion conductivity properties and a special 2-dimensional single atomic layer structure, which can be used in electrode material particles. It forms a 3-dimensional electron and ion transmission network structure. If graphene material can be successfully applied in lithium-ion batteries, it can greatly increase the charging and discharging speed of lithium-ion batteries, achieve a huge breakthrough in battery technology, and promote the realization of the new energy industry. Leap forward development.
According to Li Zhaoting, chairman of Dongxu Group, Shanghai Carbon Source Huigu is a high-tech enterprise focusing on the large-scale preparation and application technology development of graphene. It is also the only company in China that can achieve low-cost, high-quality, single-layer graphene on a large scale. It is an enterprise with chemical preparation (annual output reaches ton level). Among them, the single-layer rate of graphene prepared by the trial production line exceeds 99%, and the purity is as high as 99.9%.
Professor Guo Shouwu, chief scientist of Shanghai Carbon Source Huigu, said that the graphene-based lithium-ion battery technology released this time not only solves the problem of fast charging of lithium-ion batteries, but also breaks through the international consensus on "carbon-coated lithium iron phosphate technology" Technical blockade.
At the press conference, Tunghsu Optoelectronics signed an agreement for the implementation of the "Oxene King" production line with the Taizhou New Energy Industrial Park Management Committee, and signed a strategic agreement on R&D and industrialization cooperation with downstream application-end manufacturers such as American Kaitu Energy Company.
