    摘要: A battery capable of improving battery characteristics such as cycle characteristics is provided. The battery includes a spirally wound electrode body including a cathode and an anode spirally wound with a separator in between. The capacity of the anode includes a capacity component by insertion and extraction of light metal and a capacity component by precipitation and dissolution of the light metal, and is represented by the sum of them. The separator is impregnated with an electrolyte solution formed through dissolving a lithium salt in a solvent. As the electrolyte salt, difluoronulloxalato-O,Onullnulllithium borate, tetrafluoronulloxalato-O,Onullnulllithium phosphate or difluorobisnulloxalato-O,Onullnulllithium phosphate is used. By the formation of a stable coating, decomposition of the solvent and a reaction between precipitated lithium metal and the solvent can be prevented.

    摘要: A zinc/air cell having thin walled cup shaped anode casing and cathode casing. The cell may be a button cell having an anode comprising zinc and a cathode, which may be catalytic, comprising manganese dioxide. The anode and cathode casings have small wall thicknesses, preferably between 2 and 5 mil (0.0508 and 0.127 mm), desirably between about 2 and 3 mil (0.0508 and 0.0762 mm). There is an insulating seal ring covering at least a portion of the anode casing side walls. During cell assembly the cathode casing side wall is pushed over at least a portion of the anode casing side wall with insulating sealing disk therebetween. A tight interference fit is achieved with the outside diameter of the anode casing plus insulating seal thereon being preferably between about 2 and 4.5 mil (0.0508 and 0.114 mm) greater than the inside diameter of the cathode casing. This reduces the tendency of the casing side walls to spring back after crimping.

    摘要: As a positive electrode active material, a lithium transition metal complex oxide having a layered rock-salt structure containing lithium (Li) and containing magnesium atoms (Mg) substituted for part of lithium atoms (Li) is used. The lithium transition metal complex oxide is formed by chemical or electrochemical substitution of Mg atoms for part of Li atoms in LiCoO2, LiMnO2, LiFeO2, LiNiO2, or the like. A cell is prepared in which a negative electrode 2 and a positive electrode 1 including the lithium transition metal complex oxide (positive electrode active material) are disposed in a non-aqueous electrolyte 5 including a lithium salt, and part of Li in the lithium transition metal complex oxide is extracted by discharging the cell. Then, the electrolyte including Li is replaced with an electrolyte including Mg; and the cell is discharged, so that Mg atoms are substituted for the part of Li atoms in the lithium transition metal complex oxide.

Particularly, the present invention provides a lithium secondary battery comprising an overdischarge-preventing agent having superior effects for an overdischarge test and showing 90% or more capacity recovery after the test, by introducing lithium nickel oxide into a cathode for a lithium secondary battery comprising a lithium transition metal oxide capable of occluding and releasing lithium ions as an overdischarge-preventing agent to supply lithium ions such that irreversible capacity of an anode can be compensated or better, thereby lowering voltage of a cathode first to prevent voltage increase of an anode during the overdischarge test.
