Fossils could be key to future Li-ion EV batteries

“To improve the adoption of EVs, we need much better batteries,” says researcher Mihri Ozkan of the University of California-Riverside. “We believe diatomaceous earth, which is abundant and inexpensive, could be another sustainable source of silicon for battery anodes.”

Fossilised remains of single-celled algae called diatoms could be used to create silicon-based anodes for lithium-ion batteries, University of California scientists say.

Researchers at U-C Riverside’s Bourns College of Engineering have developed an inexpensive, energy-efficient way to create the anodes they say could lead to the development of ultra-high-capacity Li-ion batteries for electric vehicles and portable electronics.
