Project Innovation + Advantages:

Ampcera will develop a thermally modulated solid-state battery (TMSSB) incorporating a thermally modulated cell technology (TMCT), developed by EC Power, that was used in conventional lithium-ion (Li-ion) batteries to power buses during the 2022 Winter Olympic Games. The TMSSB comprises a high-capacity silicon anode and a high-voltage, nickel-rich lithium nickel manganese cobalt oxide cathode enabling an energy density of ≥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 a minute at ambient temperatures of -20°C, making the TMSSB advantageous in cold climates.
