BASF investigating sodium-air batteries as alternative to Li-air; patent application filed with USPTO

Green Car Congress

In a paper in Nature Materials , a team of researchers from BASF SE and Justus-Liebig-Universität Gießen report on the performance of a sodium-air (sodium superoxide) cell. Their work, they suggest, demonstrates that substitution of lithium by sodium may offer an unexpected route towards rechargeable metal–air batteries.
