<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery with a high output at initial ambient temperature and at -30°C, providing high discharge capacity even at high-rate discharging, and yet, with a high capacity retention ratio after endurance tests such as high-temperature preservation test and a cycle test, and excellent in initial output performance and a high-rate discharge capacity even after the endurance test. <P>SOLUTION: The nonaqueous electrolyte battery is provided with a collector, a cathode containing at least one kind of lithium-containing phosphate compound as a cathode active material expressed in LixMPO<SB>4</SB>(M: at least one kind of element selected from group 2-12 metals of the periodic table, 0<x≤1.2), an anode containing an anode active material capable of storing and releasing lithium ion, and nonaqueous electrolyte solution. The nonaqueous electrolyte solution contains cyclic carbonate having (1) chained ether, and (2) unsaturated bonds. <P>COPYRIGHT: (C)2011,JPO&INPIT |
