Thermally Modulated Solid-State Batteries for Ultra-Safe Fast-Charging Electric Vehicles
Ampcera will develop an all-climate thermally modulated solid-state battery (TMSSB) incorporating a thermally modulated cell technology (TMCT), developed by partner EC Power. “Heatable” solid-state batteries (SSBs) have the potential to provide disruptively high energy density and enable ultra-safe fast charging in EVs during cold weather, overcoming many of the consumer acceptance barriers hindering widespread adoption. Ampcera’s TMSSB combines a high-capacity silicon anode and a high-voltage, nickel-rich oxide-based cathode to enable a specific energy exceeding 400 Wh/kg. Combining the TMCT with a high ion conducting solid-state electrolyte will enable rapid charging at ambient conditions. The TMCT also enables cold startup times of less than one minute at ambient temperatures of -20°C, making the TMSSB advantageous in cold climates.
