Self-Charging Battery Generates and Stores Energy Simultaneously

Self-Charging Battery Generates and Stores Energy Simultaneously

© Xue, et al / American Chemical Society Two things that are becoming increasingly important parts of our clean technology future are improved batteries and mechanical energy harvesting devices, also known as piezoelectric devices , that can generate electricity from our everyday movements. Typically in renewable energy set up, there is the energy generator (whether using mechanical, solar, wind or other sources) and then, ideally, there is the energy storage component, very often a lithium-ion battery . In that scenario the generator turns the renewable energy into electricity and then the battery turns the electricity into chemical energy for storage. In a new technology breakthrough, researchers at Georgia Tech have developed the first self-charging power cell that is both a mechanical energy harvester and a battery at the same time. Essentially, the device skips the st...
