Potassium-Ion Batteries - Dr. Fabian Jeschull 

Research into potassium-ion batteries has increased significantly in recent years. Potassium is many times more abundant on earth and is therefore cheaper. In addition, potassium #batteries generate a higher voltage than their #lithium or #sodium-based counterparts. Despite their lower capacity, potassium energy storage systems can therefore achieve a comparable energy density to lithium iron phosphate batteries. In this video, Dr. Fabian Jeschull (Karlsruhe Institute of Technology) demonstrates the potential he sees in potassium-ion batteries.
