A team of researchers from the Technical University of Denmark (DTU) has announced the creation of a so-called super battery made from rocks, a technology that may one day replace Lithium Ion batteries used in electric vehicle production. The team claims their discovery would lead to cleaner, safer, and longer-lasting batteries that don’t rely on rare metals or end up as toxic waste. According to the DTU team behind the battery’s creation, the key to their entry into energy storage lies in the simplicity of the materials involved. More specifically, their super battery is based on potassium and sodium silicates,...
