New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

Stanford / SLAC’s new lithium-polysulfide flow battery design compared to conventional “redox” flow batteries. The new flow battery uses only one tank and pump and uses a simple coating instead of an expensive membrane to separate the anode and cathode. Credit: Greg Stewart/SLAC).
