| abstract |
This invention relates to a nonaqueous-electrolyte battery containing a current collector, a positive electrode, a negative electrode, and a nonaqueous electrolytic solution. The positive electrode contains a lithium-containing phosphoric acid compound represented by LixMPO 4 as a positive-electrode active material, where M is at least one element selected from Group-2 to Group-12 metals of the periodic table, and x satisfies 0<x≦1.2. The negative electrode contains a negative-electrode active material capable of occluding and releasing lithium ions. The nonaqueous electrolytic solution contains a chain ether and a cyclic carbonate having an unsaturated bond. |
