PROBLEM TO BE SOLVED: To provide an organic electrolyte battery excellent in both load characteristic and high temperature storage characteristics. SOLUTION: As for the organic electrolyte battery, which contains a positive electrode 1, a negative electrode 2, and an organic electrolyte 4, a lithium content material, of which the specific surface area is 1.0 m<2> /g or more, is used as a negative-electrode active material. The negative electrode in a 90% charged state to the standard capacity of the battery has the quantity of carbon atom, which is obtained by the peak of 286 to 287 eV based on the carbon atom originated from the C-O by X-ray photoelectron spectroscopic analysis, is 6.5 atom.% or less. And moreover, the quantity of phosphorus atom, which is obtained by the peak of 133 to 135 eV based on phosphorus originated from the Pox, is 1 atom.% or more, or the quantity of boron atom, which is obtained by the peak of 192 to 193 eV based on boron originated from the BOx, is 1 atom.% or more. |
