USC Scientists Create New Battery That’s Cheap, Clean, Rechargeable… and Organic

07.07.2014 | |

Scientists at USC have developed a water-based organic battery that is long lasting, built from cheap, eco-friendly components.

The new battery – which uses no metals or toxic materials – is intended for use in power plants, where it can make the energy grid more resilient and effic

ient by creating a large-scale means to store energy for use as needed.

“The batteries last for about 5,000 recharge cycles, giving them an estimated 15-year lifespan,” said Sri Narayan, professor of chemistry at the USC Dornsife College of Letters, Arts and Sciences and corresponding author of a paper describing the new batteries that was published online by the Journal of the Electrochemical Society on June 20. “Lithium ion batteries degrade after around 1,000 cycles, and cost 10 times more to manufacture.”
