NOVELTY - A lithium ion battery has a positive electrode adhered to a current collector connected with a cathode which is dissolved in a solvent comprising transition metal ion, a separator, an electrolyte and shell material. Positive electrode comprises active material, binder and conductive agent. The current collector is stainless steel, nickel, titanium, platinum, palladium, gold, silver, copper or conductive graphite. The separator consists of inorganic lithium ion conducting film, cation exchange membrane or anion exchange membrane. The electrolyte contains solute and solvent.    USE - Lithium ion battery is used as power supply for vehicles, medical device and portable electronic product.    DETAILED DESCRIPTION - A lithium ion battery has a positive electrode adhered to a current collector connected with a cathode which is dissolved in a solvent comprising transition metal ion, a separator, an electrolyte and shell material. The positive electrode comprises active material, binder and conductive agent. Active material is oxide, lithium transition metal and/or sulfate-fluoride complex of phosphate, sulfide carbonate or oxalate. The transition metal is titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, tin and/or lead. The solvent is water, N-methyl pyrrolidone, dimethyl formamide, dimethyl acetamide, alcohol, methanol, dimethyl sulfoxide, ether, ethyl acetate, tetrahydrofuran, dioxolane, dioxane, acetone, ethylene carbonate, propylene carbonate, methyl ethyl carbonate. The current collector is stainless steel, nickel, titanium, platinum, palladium, gold, silver, copper or conductive graphite. The separator consists of inorganic lithium ion conducting film, cation exchange membrane or anion exchange membrane. The electrolyte contains solute which is chosen from oxide of lithium, sulfate, nitrate, oxalate, acetate, phosphate and hydroxide, and solvent which is chosen from water, N-methyl pyrrolidone, N-methyl formamide, alcohol, methanol, dimethyl sulfoxide, ether, ethyl acetate, tetrahydrofuran, dioxane, acetone, ethylene carbonate, propylene carbonate, methyl ethyl carbonate. The shell material is metal, inorganic ceramics, plastics, rubber, resin or metal. The cathode shell in the lithium ion battery is tubular shape, spherical shape, and/or polyhedral shape.
