Professor Ying Wang’s ammonium-ion battery has an aqueous electrolyte containing high-concentration salts that result in a significantly depressed freezing point for operation at sub-zero temperatures in space systems.
The battery design has the potential to store 1 kWh per kg or higher—four times greater than lithium-ion battery technology, which would be transformative for electrifying transportation, especially heavy-duty vehicles such as airplanes, trains, and submarines.
