Amazing New Grid-Scale Battery Has Electrodes That Don’t Degrade

A new battery technology may pave the way for cheap, long-lived power storage that can quickly pump electricity into the grid to compensate for fluctuating renewables like wind and solar.

Developed by Yi Cui and colleagues at Stanford University in California, the battery’s key advantage is its electrodes, which can run for a thousand charge cycles without degrading. Battery electrodes typically degrade over time as ions in a battery cell repeatedly slam into them and are ripped away again.

By coating the negatively charged cathode in copper hexacyanoferrate and using an anode made of activated carbon and a conductive polymer – compounds that allow electricity-carrying ions to move easily in and out – the team were able to build a prototype battery with electrodes that didn’t lose capacity over time.
