BYD Launches the Solid-State Battery Revolution

BYD reveals important details about its solid-state batteries (SSB), moving beyond the research phase.

This announcement from BYD shows that SSBs are now transitioning to tangible demonstration and preparation for industrial production. BYD’s battery combines nickel-rich cathodes, a silicon-based anode, and a solid sulfide electrolyte. According to the figures provided, its 60 Ah cell achieves approximately 400 Wh/kg, can start down to -40 °C, and charges quickly, reaching 80% charge in ten minutes. These characteristics address two major issues of conventional batteries: performance loss at low temperatures and the impedance between materials. BYD plans limited demonstrations around 2027 and a ramp-up in production towards 2030, initially targeting high-end models.

BYD ready as early as 2025?

Globally, other players are also making strides. In Europe, Mercedes, BMW, and QuantumScape are testing prototypes on the road. In Asia, SK On, Farasis, and CATL are launching pilot projects and small series. ProLogium, Panasonic, and Nissan are developing pilot lines and preparing factories. These initiatives indicate that solid batteries are set to be used as early as 2025, with broader deployment expected in the following years.

SSBs offer two key advantages: they are safer than conventional batteries and allow for increased energy storage and charging speed. They also provide manufacturers the opportunity to produce closer to consumer markets, thereby reducing supply chain risks.
