In the latest battery breakthrough claim of the week, researchers from the University of Waterloo released a new paper claiming a breakthrough involving the use of negative electrodes made of lithium metal.
They claim that it has the potential to “dramatically increase battery storage capacity,” which could triple the range of electric vehicles.
The main issue with Li-metal batteries is the quick degradation due to dendrites forming in the cells.
Quanquan Pang, who led the research while he was a PhD candidate at Waterloo (now a post-doctoral fellow at MIT), claims to have solve the issue by “adding a chemical compound made of phosphorus and sulfur elements to the electrolyte liquid that carries electrical charge within batteries.”
They claim that the compound reacts with the lithium metal electrode in an already assembled battery to “spontaneously coat it with an extremely thin protective layer.”
It enables them to use lithium metal electrodes in battery …
