PURPOSE: A lithium battery comprising a separator having an inorganic protection coating is provided to inhibit movement of a cathode active material, thereby reducing self-discharge. CONSTITUTION: The lithium battery comprises a cathode, an anode, and a separator inserted between the cathode and the anode, wherein the separator comprises an inorganic protection coating formed on at least one surface thereof. The inorganic protection coating is single ion conducting glass having lithium ion conductivity, and more particularly lithium nitride, lithium silicate, lithium borate, lithium aluminate, lithium phosphate, lithium phosphorus oxynitride, lithium silicosulfide, lithium germanosulfide, lithium lanthanum oxide, lithium titanium oxide, lithium borosulfide, lithium aluminosulfide, lithium phosphosulfide or a mixture thereof. |
