Eggshells -Green Sustainable Energy Storage
World First - From Biowaste to Electrode Source: KIT Better, New Batteries This is a world first. A sustainable green energy storage system made from eggshells. An international research team based at the distinguished Karlsruhe Institute of Technology (KIT) in Germany just announced their breakthrough innovation. It's a green energy storage option that could lead to the development of better batteries. Working with Eggshells The scientists created an electrode from pulverized eggshells. They experimented with eggshells because they contain big amounts of calcium carbonite which can store lithium. They used the electrode against a metallic lithium anode placed in a solution. The battery they created maintains a capacity retention of 92% after one thousand plus charge and recharge cycles. Greener Future The team believes their discovery can be used as low cost, lithium-ion capacitors. This is the first time that biowaste has b...
