Abstract
The present disclosure provides methods of compensation for capacity loss resulting from cycle-induced lithium consumption in an electrochemical cell including at least one electrode. Such methods may include adding a lithiation additive to the at least one electrode so as to create a lithium source. The lithium source compensates for cycle-induced lithiation loss such that the electrochemical cell having the lithiation additive experiences total capacity losses of less than or equal to about 5% of an initial capacity prior to cycling of lithium. The lithiation additive includes a lithium silicate represented by the formula LiH, where H=LiSiOand where 0≤y≤3.75 and 0≤z≤2 and u is a useable portion of y, 0≤u≤y. The lithium source may include and LiSi, where 0≤m≤4.4.
