Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery with good load characteristics and high cycle characteristics.
SOLUTION: A nonaqueous electrolyte battery has a negative electrode 1, a positive electrode 2, and a nonaqueous electrolyte. The negative electrode 1 is made of metallic lithium, a lithium alloy, or a material (a carbon material for example) capable of doping/undoping lithium. The positive electrode 2 is made of a composite oxide of lithium and a transition metal, for example. The nonaqueous electrolyte contains 1,3-dimethyl-2-imidazolinon. By adding 0.01 vol.% or more but less than 1 vol.% 1,3-dimethyl-2-imodazolinon, the load characteristics of the battery is greatly increased. The battery constitution is allowable to be a regular lithium ion battery, a polymer solid electrolyte battery, or a polymer gelled electrolyte battery.

SOLUTION: The phosphoric ester represented by the formula is used and preferably contained in a nonaqueous solvent by not less than 3 vol.% to not more than 20 vol.%. In the formula, R1 , R2 , and R3 are each an alkyl group or aryl group. For example, triethyl phosphate, triphenyl phosphate, ethyldimethyl phosphate, and the like are used, with trimethyl phosphate being particularly desirable. An electrolytic solution contains LiBF4 as an electrolyte, and a manganese oxide or complex oxides of lithium and manganese for use in the positive electrode should preferably have a spinel type crystalline structure. A phosphoric ester compound inhibits the elution of Mn in the positive electrode material into the nonaqueous electrolyte.

Abstract: PURPOSE:To retard the deterioration of a negative electrode by specifying the overvoltage in charging. CONSTITUTION:Overvoltage in a charging current density of 1mA/cm under a potential variation of 1mV/sec. is set to 300mV or less. Thereby, the generation of dendrite which deteriorates a lithium electrode is retarded and the deterioration of the negative electrode attendant on repeated charge-discharge cycles is also retarded. The content of phosphorus as determined by X-ray photoelectric special (XPS) analysis in which an angle of the specimen surface of the lithium negative electrode to an analyzer is set to 35 deg. is specified to 0.5 atomic percent or more. This retards the reaction of lithium with a nonaqueous electrolyte and the formation of dendrite.

Abstract: PROBLEM TO BE SOLVED: To provide a positive electrode active material suppressing the generation of gas inside a battery. SOLUTION: A tungstic acid compound is attached to composite oxide particles mainly composed of lithium nickelate, and heat-treated to form the positive electrode active material. Preferably, at least one of a sulfuric acid compound, a nitric acid compound, a boric acid compound and a phosphoric acid compound is attached together with the tungstic acid compound to the composite oxide particles and heat-treated. The generation of gas inside the battery can be suppressed in the secondary battery using the positive electrode active material manufactured by this method and having 0.15 wt.% or less of carbonate ion content. Heat treatment is performed after the tungstic acid compound and the compound such as the sulfuric acid compound other than the tungstic acid compound are mixed and attached to the composite oxide particles. Alternatively, the compound such as the sulfuric acid compound other than the tungstic acid compound may be first attached to the composite oxide particles and heat-treated, and then the tungstic acid compound may be attached and heat-treated.
