Abstract:
1. A lithium-ion electrochemical cell, the cell comprising: (i) an anode, the anode comprising an anode active material in electronically conductive contact with an anode current collector, wherein the anode active material is selected from the group consisting of lithium metal, carbon, lithium-intercalated carbon, lithium nitrides, lithium alloys, and lithium-alloy-forming compounds of tin, silicon, antimony, aluminum or titanium oxide; (ii) a cathode exhibiting an upper charging voltage in the range of 3 to 5 volts with respect to a Li/Li a cathode current collector comprising: a cathode active material placed on the top of the coating, the cathode active material comprising a lithium insertion transition metal oxide or phosphate; the lithium compound being at a concentration from about 0.1 to 3 molar, wherein the lithium compound is CF the additive providing corrosion protection of the cathode current collector, the anode current collector, or both current collectors; wherein the additive is selected from the group consisting of LiBOB, LiF, LiFOB, LiPF
