Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lithium-ion battery keeping high-temperature preservation properties at temperatures of 50°C or more and having improved output properties at room temperature.SOLUTION: A lithium-ion battery comprises: a cathode capable of the occlusion and release of lithium ions; an anode capable of the occlusion and release of lithium ions; a separator arranged between the cathode and the anode; and an electrolyte. In the lithium-ion battery, the anode is coated with a lithium-ion conductive polymer, therefore high-temperature preservation properties at temperatures of 50°C or more can be kept and output properties at room temperature can be improved.
