OSU team demonstrates concept of potassium-air battery as alternative to lithium-air systems

Green Car Congress

Researchers at Ohio State University (OSU) have demonstrated the concept of a potassium-air (K?O Potassium, an alkali metal similar to lithium (and sodium) can be used in a rechargeable battery. For comparison, they built a Li?O O 2 battery (0.5 M KPF6 in DME) at a current density of 0.16 Credit: ACS, Ren and Wu. O 2 batteries.In

OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

A team at the Ohio State University has developed a membrane that regulates bi-directional ion transport across it as a function of its redox state and that could be used as a programmable smart membrane separator in future supercapacitors and redox flow batteries. —Herya and Sundaresan. plugin EVs to Tesla’s 85 kWh battery pack).
