NOVELTY - Compensation (M1) for capacity loss resulting from cycle-induced lithium consumption in an electrochemical cell including at least one electrode, comprises adding a lithiation additive to the electrode to create a lithium source that compensates for cycle-induced lithiation loss that occurs when lithium is cycled in the electrochemical cell so that the electrochemical cell experiences a total capacity loss of less than or equal to 5% of an initial capacity prior to cycling of lithium in the electrochemical cell, where the lithiation additive comprises a lithium silicate (I). USE - The methods are useful for: compensation for capacity loss resulting from cycle-induced lithium consumption in an electrochemical cell including at least one electrode; and forming a pre-lithiated electrode for an electrochemical cell (all claimed). ADVANTAGE - The methods: improve electrodes and reduce operation inefficiencies resulting from loss of active lithium ion during the first cell cycle; and utilizes pre-lithiation that creates a lithium reservoir in the cell, the reserved lithium compensates for lithium lost during cycling, including during the first cycle, of the electrochemical cell so as to decrease capacity loss over time. DETAILED DESCRIPTION - Compensation (M1) for capacity loss resulting from cycle-induced lithium consumption in an electrochemical cell including at least one electrode, comprises adding a lithiation additive to the electrode to create a lithium source that compensates for cycle-induced lithiation loss that occurs when lithium is cycled in the electrochemical cell so that the electrochemical cell experiences a total capacity loss of less than or equal to5% of an initial capacity prior to cycling of lithium in the electrochemical cell, where the lithiation additive comprises a lithium silicate of formula (LiuHr) (I). Hr = Liy-uSiOz; y = 0-3.75; z = 0-2; and u = 0-y, where u is useable portion of y. INDEPENDENT CLAIMS are also included for: (a) forming (M2) a pre-lithiated electrode for incorporation into an electrochemical cell, comprising combining a lithiation additive with an electroactive material and a current collector (310) in an environment comprising oxygen that is substantially free of water and has a dew point of -100 to 0degrees Celsius, where the lithiation additive comprises (I); and (b) forming (M3) a pre-lithiated electrode for an electrochemical cell, comprising forming a lithiation layer (320) comprising a lithiation additive adjacent a current collector in an environment comprising oxygen that is substantially free of water and has a dew point of -100 to 0degrees Celsius, where the lithiation additive comprises (I) and forming an electroactive layer on at least one exposed surface of the lithiation layer. DESCRIPTION OF DRAWING(S) - The figure illustrates a negative electrode having a lithiation layer.
