Abstract
In this disclosure, we describe a new chemical treatment that can be performed on lithium metal and lithium alloy surfaces to selectively remove LiH defects. This treatment utilizes an exclusive reaction between LiH and trialkyl borane to form lithium borohydride complexes, which can be easily washed away from surface using an inert organic solvent. This treatment can be useful for lithium metal and lithium alloy anodes for high energy batteries.
