Fire quenching collector to create lightweight lithium batteries

Sat, 10/24/2020 - 18:04 -- Vic

Scientists at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory have reengineered one of the heaviest battery components—sheets of copper or aluminum foil known as current collectors—so they weigh 80% less and immediately quench any fires that flare up.

“The current collector has always been considered dead weight, and until now it hasn’t been successfully exploited to increase battery performance,” said Yi Cui, a professor at SLAC and Stanford and investigator with the Stanford Institute for Materials and Energy Sciences (SIMES) who led the research.
