New Kind of Self-Charging Battery Generates and Stores Energy Simultaneously

New Kind of Self-Charging Battery Generates and Stores Energy Simultaneously | Kongossa | Scoop.it
Usually energy-generating devices require a separate battery for storing energy, but for the first time, a single power cell is capable of generating and storing energy at the same time.

 

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 step of generating electricity and converts the mechanical energy directly into chemical energy.
