Low-Cost, High Areal Capacity, Anode-Free Sodium-Metal Batteries Enabled by Solid Electrolytes
Project Innovation + Advantages:
24M Technologies will develop low-cost and fast-charging sodium metal batteries with good low-temperature performance for EVs. 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, fastcharging electrolyte developed using machine learning and automated high-throughput screening technology, and (3) a solid electrolyte-based separator to enable a high-energy density anode-free configuration.
