Lithium metal (LiM) alloys, owing to their intrinsic high specific capacity, are considered to be very appealing negative electrodes that may be exploited for the replacement of conventional graphite in advanced design, lithium-ion batteries. LiM alloys, however, undergo large volume expansion and contraction during the charge–discharge cycling, which induces mechanical disintegration that results in very poor cycle life.
