Abstract
A battery capable of improving the energy density and improving the battery characteristics such as cycle characteristics and high temperature storage characteristics. A cathode and an anode are oppositely arranged with a separator in between. The open circuit voltage in full charge is in the range from 4.25 V to 6.00 V. The separator has a base material layer and a surface layer. The surface layer opposed to the cathode is formed from at least one from the group consisting of polyvinylidene fluoride, polytetrafluoroethylene, polypropylene, and aramid.
