BYD has already produced its first solid-state cells

Chinese car and battery manufacturer BYD apparently already produced its first solid-state cells last year. The source for this is not an anonymous informant,

And even after the demonstration applications, there are no plans to start series production in the near future: A truly large-scale introduction of solid-state batteries could possibly only take place after 2030, Sun is quoted in the reports. However, the quantities are still too small – especially for sulphide electrolytes: “It doesn’t really make a lot of sense to talk about cost in the absence of volume.” Other technology paths for solid-state cells are oxides and polymers. Although many companies and institutions have been working on the technology for years due to these advantages, battery cells with ‘real’ solid electrolyte are still very rare – as BYD’s timetable also suggests.
