National Renewable Energy Laboratory (Golden, CO) will assess data and parameters representing the risks of next-generation cells.The TMCT also enables cold startup times of less than a minute at ambient temperatures of -20☌, making the TMSSB advantageous in cold climates. Combining the TMCT with a high ion-conducting solid-state electrolyte will enable rapid charging at ambient conditions. The TMSSB comprises a high-capacity silicon anode and a high-voltage, nickel-rich lithium nickel manganese cobalt oxide cathode. Ampcera (Tuscon, AZ) will develop a solid-state battery 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.24M’s cell design will incorporate (1) its ultra-thick SemiSolid cathode made up of advanced cobalt-free, nickel-free sodium cathode active material, (2) an advanced wide-temperature, fast-charging electrolyte developed using machine learning and automated high-throughput screening technology, and (3) a sodium super ionic conductor. 24M Technologies (Cambridge, MA) will develop low-cost and fast-charging sodium metal batteries with good low-temperature performance for EVs.ARPA-E selected the following 12 teams from universities, national laboratories and the private sector to address and remove key technology barriers to EV adoption by developing next-generation battery technologies: The EVs4ALL program is managed by DOE’s Advanced Research Projects Agency-Energy (ARPA-E).
