'Spillway' for electrons could keep lithium metal batteries from catching fire

'Spillway' for electrons could keep lithium metal batteries from catching fire San Diego CA (SPX) Mar 13, 2020
Nanoengineers at the University of California San Diego developed a safety feature that prevents lithium metal batteries from rapidly heating up and catching fire in case of an internal short circuit. The team made a clever tweak to the part of the battery called the separator, which serves as a barrier between the anode and cathode, so that it slows down the flow of energy (and thus heat) Source: NanoDaily.com https://www.energy-daily.com/reports/Spillway_for_electrons_could_keep_lithium_metal_batteries_from_catching_fire_999.html
