Scientists have developed a material to improve performance of lithium-ion batteries. It stimulates speed that makes them even more important for consumer electronics, electric vehicles, and solar grid storage. The Rensselaer Polytechnic Institute (RPI) conducted the research to improve charging speed and performance. The researchers discovered that changing cobalt oxide (CoO) to vanadium disulfide (VS₂) in the cathode might help. A professor at RPI, Nikhil Koratkar said that the material
