GAC Group says it has achieved a breakthrough in graphene-based fast-charging battery technology and that its vehicle model Aion V will be equipped with the new battery, which is to start production in September.
GAC says that in recent years, graphene, a new material with excellent electrical conductivity, has been the key to breakthroughs in battery technology.
Aion V, the first vehicle to be equipped with the new battery, is undergoing winter testing and is initially scheduled for mass production in September this year.
At the "2020 GAC Tech Day" held in July, GAC Group demonstrated its 3DG (three-dimensional graphene) production technology with independent intellectual property rights, solving the issue of high costs of graphene, it is claimed. It says the simple, stable, and efficient production method reduces costs to only one-tenth of the conventional method.
After achieving low-cost and large-scale production of graphene, GAC Group says it has also made major breakthroughs in the downstream application of its use. Among them, the electric vehicle industry is most interested in the graphene-based super-fast-charging battery. This graphene-based battery has a 6C fast charge capability, combined with a 600A high-power charger, can be recharged to 80% capacity in 8 minutes. GAC says the battery has also passed the most stringent safety test – Battery Shooting Test, possessing quality and reliability of the highest standard.
GAC says the graphene-based battery technology will significantly shorten charging time, as well as greatly extend battery life, solving the current "pain points" of pure electric vehicles.
