Honda’s research arm, Honda R&D, signs a multiyear joint research agreement with QuantumScape, a California-based solid-state battery company, to develop and manufacture solid-state battery cells. The companies announce the deal on June 18. Honda is described as the second major automaker to formally partner with QuantumScape after Volkswagen, which previously established a similar relationship. The agreement is presented as part of Honda’s broader battery and technology strategy. CNET notes the move as a “surprise” bet on solid-state batteries, while The Next Web reports that the deal comes after Honda completes an in-depth technology review process and also in the context of Honda having scrapped its EV lineup, redirecting attention to alternative battery research.

Market coverage from Yahoo Finance highlights that the announcement lifts QuantumScape’s share price, with the stock rising following the pact. Yahoo Finance also reports that solid-state battery peers, including Solid Power, gain in sympathy with QuantumScape’s move. Across sources, the focus remains on the research and cell development partnership and its immediate impact on related stock prices.
