Abstract: An electrolyte solution includes a solvent; an electrolyte salt; and a LA:LB complex represented by the following general formula I: [(FnA)x-L] (I) In formula I, A is boron or phosphorous, F is fluorine, L is an aprotic organic amine, n is 3 or 5, when n=3, A is boron, and when n=5, A is phosphorous, x is an integer from 1-3, and at least one N atom of the aprotic organic amine, L, is bonded directly to A. The LA:LB complex is present in the solution in an amount of between 0.01 and 5.0 wt. %, based on the total weight of the electrolyte solution. [(FnA)x-L]  (I)

Abstract: An electrochemically active material includes, prior to incorporation in an electrochemical full cell, reversible lithium corresponding to between 4% and 50% of the reversible capacity of the electrochemically active material. The electrochemically active material has a lithium consumption rate between 0.05% and 0.2%.
