Abstract
A lithium ion secondary battery is disclosed that can inhibit generation of gas due to decomposition of a non-aqueous electrolyte solution. The lithium ion battery includes a cathode, a non-aqueous electrolyte solution and an anode, wherein the cathode includes a conductive material, a layered niobium-containing oxide that coats a surface of the conductive material, and a lithium-containing oxide active material having an upper-limit potential to a redox potential of metal lithium of no less than 4.5 V (vs. Li/Li+).
Claims10
A method for manufacturing a lithium ion battery comprising:
- coating only a surface of a conductive material with a layered niobium-containing oxide to form a complex;
- mixing the complex and a lithium-containing oxide active material having an upper-limit potential to a redox potential of metal lithium of no less than 4.5 V (vs. Li/Li+) to obtain a cathode mixture;
- manufacturing a cathode from the cathode mixture;
- and
- manufacturing a power generation element from the cathode, a non-aqueous electrolyte solution and an anode.
