Berkeley Lab team designs active polyelectrolyte binder that allows for a doubling in capacity of conventional Li-sulfur battery

Green Car Congress

A team of researchers led by scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed an active polyelectrolyte binder (PEB) that actively regulates key ion transport processes within a lithium-sulfur battery, and have also shown how it functions on a molecular level.

Researchers find synergy between lithium polysulfide and lithium nitrate as electrolyte additives prevent dendrite growth on Li metal anodes

Green Car Congress

Lithium metal, having a high theoretical specific capacity of 3,860 mAh g -1 and the most negative electrochemical potential among anode materials, has been considered an ideal anode in lithium battery systems over the past four decades.
