WOLFSBURG -- Volkswagen Group is eyeing producing its own solid state battery cells, with possible serial production from 2024 or 2025.
"We must not make ourselves dependent on a few Asian manufacturers in the long term," VW Group CEO Herbert Diess said after the group reported second-quarter results.
He said advances in ceramic separators had raised the viability of mass production of solid state batteries.
A solid state battery factory would likely be in Europe, or even in Germany under the right conditions, Diess said.
Battery cells are a key battleground in the automotive industry as it shifts to electric mobility.
Tesla is in talks with authorities in Germany and the Netherlands for its first major European factory to build cars and their batteries under one roof, the Wall Street Journal reported on Monday, citing officials involved in the talks.
