The Chinese car manufacturer GAC MOTOR recently published a breakthrough in the production of batteries for electric cars in a press release: with the help of graphene technology, the battery is to be charged to 80 percent in only eight minutes. The previous main issue of graphene technology - the very high price - has been solved with the innovation, according to the company. With its 3DG production technology, manufacturing costs are to be reduced to a tenth.

But what is to be made of this innovation? Professor Ulrich S. Schubert points out to MDR that the information provided by the company GAC MOTOR is not detailed enough to make a conclusive assessment. In principle, graphene is a promising material. However, whether the production costs are so much lower than before can hardly be assessed without further information. "Apart from those who work in the company, no one is sure what kind of graphene is used, nor is the specific manufacturing process clear," says Schubert. The company also does not provide any details about the type of testing.
