Flow batteries for grid storage?
The idea of combining a battery and capacitor between a pair of electrodes is appealing. Let’s push the envelope on this and see how we can develop a device that can deliver high power and store huge amounts of energy.
Researchers at Drexel University are developing an electrochemical flow capacitor (EFC) that combines the storage capabilities of batteries with the much longer cycle life and power output of supercapacitors. The team’s goal is to improve the stability of the energy grid and ease the integration of renewable energy sources.
