For the time being, German car manufacturer will continue purcharsing the core of their electric cars, the battery, in China. This shows the Grünecker patent study for the IAA 2021. Partner Jens Koch and patent attorney Sebastian Flach analyzed the patent applications around batteries for electric cars worldwide.
"The basis for the best batteries, at the moment, comes from China," says Jens Koch: "German car manufacturers are dependent on Chinese suppliers and lose part of their previous value creation." While German manufacturers invested little in battery research or even stopped it, battery producers from China have caught up significantly in terms of patents. Today, they are by far the technical leaders.
