<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery in which an overcharge cycle and safety during overcharging are improved by using a monoclinic β-type titanium complex oxide having superior overcharge resistance as a negative electrode active material. <P>SOLUTION: The nonaqueous electrolyte battery is equipped with a sheath material, a cathode housed in the sheath material and containing a cathode active material, an anode housed in the sheath material and containing the monoclinic β-type titanium complex oxide, and a nonaqueous electrolyte filled into the sheath material. In the nonaqueous electrolyte battery, when OCP (open-circuit potential) curves of the potential of the cathode and the potential of the anode are described, an absolute value of the inclination of anode potential which reaches a full charge state is larger than that of the inclination of cathode potential which reaches the full charge state. <P>COPYRIGHT: (C)2011,JPO&INPIT |
