摘要： A lithium ion battery includes: a positive electrode capable of occluding and emitting lithium ions; a negative electrode that is capable of occluding and emitting lithium ions; a separator disposed between the positive electrode and the negative electrode; and an electrolytic solution. The negative electrode of the lithium ion battery is coated with a lithium ion conductive polymer. The lithium ion battery maintains high-temperature storage characteristics at temperatures of 50° C. or more and output characteristics at room temperature of the lithium ion battery are improved.
