Additive breakthrough paves way to safer lithium-ion batteries

Tue, 11/10/2020 - 15:42 -- Paul Crompton

Researchers from Columbia University's engineering department in the US have reported that alkali metal additives, such as potassium ions, can prevent dendritic growth in lithium-ion batteries.

The team found small amounts of potassium salt added to a conventional lithium battery electrolyte produced unique chemistry at the lithium/electrolyte interface.
