Abstract
Electrolytes comprising a solvating solvent, lithium salt and a halogenated alkane in an amount of 0.05% to 5% by weight of the electrolyte improve the cycling performance of lithium ion batteries and in particular lithium ion batteries having lithium metal anodes or anode-less anodes with Li intercalating cathode (e.g., cathodes comprised of layered nickel, manganese cobalt oxides).
Claims20
An electrolyte comprising a solution comprised of a solvating solvent, lithium salt and a halogenated alkane in an amount of 0.05% to 5% by weight of the electrolyte.
20, The battery of claim 19, wherein the layered oxide is comprised of Ni, Mn, Co and the Ni is at least 50% by mole of the Ni, Mn and Co in the layered oxide.
