Self-charging power cell stores energy

Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries.

“People are accustomed to considering electrical generation and storage as two separate operations done in two separate units,” says Zhong Lin Wang, a professor in the School of Materials Science and Engineering at the Georgia Institute of Technology.

“We have put them together in a single hybrid unit to create a self-charging power cell, demonstrating a new technique for charge conversion and storage in one integrated unit.”
