BYD has already produced its first solid-state cells - electrive.com

BYD has produced its first solid-state battery cells on a pilot line in 2024, with mass demonstration expected around 2027 and large-scale production after 2030. The company is focusing on sulphide electrolytes for solid-state cells, aiming to achieve cost parity with current NCM cells at scale. BYD plans to use these batteries primarily in high-end models while maintaining LFP cells for other vehicle segments.
