NOVELTY - The electrochemical cell comprises an anode (215), a metal-based cathode (210) coupled to the anode, and an electrolyte solution (205) adapted to activate the anode and the cathode. The electrolyte solution has a lithium dinitramide salt as the primary salt with a molarity of 0.8 M, and 1.75-2.25 wt.% of an additive that includes a non-organic additive consisting of lithium bis(oxalate)borate, lithium bis(trifluoromethanesulfonyl)imide, lithium tetrafluoroborate, lithium perchlorate, lithium boride or lithium hexafluorophosphate and an organic additive consisting of vinylene carbonate.    USE - The electrochemical cell such as battery (claimed) including a lithium or lithium-ion battery is useful in a motor vehicle to power an electronic system.    ADVANTAGE - The electrochemical cell is economic to manufacture, exhibits improved thermal stability, excellent discharge capacity and good battery performance, and minimizes the risk of unintentionally producing hydrofluoric acid through exposure to water.    DETAILED DESCRIPTION - The electrochemical cell comprises an anode (215), a metal-based cathode (210) coupled to the anode, and an electrolyte solution (205) adapted to activate the anode and the cathode. The electrolyte solution has a lithium dinitramide salt as the primary salt with a molarity of 0.8 M, and 1.75-2.25 wt.% of an additive that includes a non-organic additive consisting of lithium bis(oxalate)borate, lithium bis(trifluoromethanesulfonyl)imide, lithium tetrafluoroborate, lithium perchlorate, lithium boride or lithium hexafluorophosphate and an organic additive consisting of vinylene carbonate and 4-vinyl 3-dioxolon-2-one, where the lithium boride is represented as LiB12-xF12Hx. An INDEPENDENT CLAIM is included for an electrolyte solution for a battery.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic perspective view of a battery.
