Provided is a lithium battery that improves storage characteristics at a high temperature of 100 ° C. or more, is excellent in large current discharge characteristics, large current pulse discharge characteristics, low temperature discharge characteristics, and the like, and has superior cost. In a positive electrode 10 containing manganese dioxide as a positive electrode active material, a negative electrode 11 containing metal lithium or a lithium alloy as a negative electrode active material, and a lithium battery 1 containing an organic electrolyte, manganese dioxide has a low crystallinity and a specific ratio. The surface area is 8 to 28 m 2 / g. [Selection] Figure 1 |
