The unusual properties of graphene promise to improve a lot of battery performance. The most expected of them - due to the better conductivity of electrons in graphene - is the fast charging of batteries. Without significant breakthroughs in this area, electric vehicles will remain less comfortable in regular operation than cars with internal combustion engines. The Chinese promise to reverse the situation in this area soon.
According to the Internet resource , a major Chinese car manufacturer Guangzhou Automobile Group () intends to launch mass production of car batteries based on graphene by the end of the year. Development details have not been released. At the moment, it is only known that 3DG “three-dimensional structural graphene” will be used as the basis for “graphene” battery cells.
3DG technology is developed by the Chinese company Guangqi and protected by patents. GAG became interested in graphene for batteries in 2014. At some stage of research, Guangqi came under the wing of the Chinese auto giant, and in November 2019, promising “graphene” batteries with ultra-fast charging were presented. According to the manufacturer, batteries based on 3DG material are charged up to 85% capacity in just 8 minutes. This is an attractive indicator for the operation of an electric vehicle.
Data on the capabilities of "graphene" batteries was collected after trial operation and testing of new battery cells, modules and battery packs both separately and as part of an electric vehicle. According to the manufacturer, "the service life and safety of use of Super Fast Batteries meet the standards of operation." Mass production of "graphene" batteries will begin at the end of this year. In the cars of Guangzhou Automobile Group, most likely, the novelty will be registered as early as next year.
