    Abstract: PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte battery, which permits expansion/ shrinkage of elements caused by repeated charging and discharging, has a relieved internal pressure rise, and prevents separation of a laminated layer from a current collector, so that deterioration in cycle characteristic, particularly deterioration at high temperature, is suppressed. SOLUTION: The non-aqueous electrolyte battery of the invention includes a wound body in which a belt-shaped positive electrode, a belt-shaped negative electrode ad belt-shaped separator were wound around a center pin using it as a winding axis in a laminated condition; a tubular battery case serving to receive the wound body and having a bottom; and a non-aqueous electrolyte contained in the battery case. The center pin is made of a material having a melting point of 350 deg.C or less.

    Abstract: PROBLEM TO BE SOLVED: To made nonauqeous solvent used for nonaqueous electrolyte nonflammable and to improve the cycle characteristic of a battery by including phosphate compound or radical polymerization inhibitor in the nonaqueous electrolyte. SOLUTION: Phosphate compound contained in nonaqueous electrolyte is expressed by formula I. In the formula I, R1-R4 are a substituted or non- substituted cyclic aromatic group; and is a substituted or non-substituted cyclic aromatic group or heterocycle. Preferably, R1-R4 are each a phenyl group, a benzyl group, etc., and A is an ortho, meta, or para position substituted phenyl group, substituted biphenyl group, or bisphenol A. A phenotiazine compound expressed by formula II is preferable for the radial polymerization inhibitor contained in the nonaqueous electrolyte. In formula II, R5-R7 are each hydrogen atom, a substituted or non-substituted straight chain or branch alkyl group, etc., and X is absent or 1-2 (integer) oxygen atoms.

    Abstract: PROBLEM TO BE SOLVED: To make a nonaqueous solvent flame-resistant and to improve the cycle characteristic of a battery by providing a positive electrode, a negative electrode and a nonaqueous electrolyte with electrolyte disolved in a nonaqueous solvent, including a specific phosphate compound and a specific phosphagen compound as the nonaqueous solvent. SOLUTION: A nonaqueous solvent to be used contains a phosphate compound expressed by formula I and a phosphagen compound expressed by formula II. In the formula, R1 -R4 represent substituted or nonsubstituted cyclic aromatic groups, and A represents a nonsubstituted cyclic aromatic group or a heterocycle. In the formula, R5 , R6 represent a straight chain or branched alkyl group, a cyclic saturated alkyl group or an alkylene group, and (n) is an integer of 1-100. Flame resistance is displayed because of containing the phosphate compound in the nonaqueous solvent, and the cycle characteristic of a battery is improved since containing the phosphagen compound is contained. In this nonaqueous electrolyte battery, a wound layer body with a positive electrode, and a negative electrode wound through a separator is charged in a battery can.

    Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte cell preventing vaporization and decomposition of the electrolyte based on an organic solvent at wide range of temperature, with high safety at short circuit, excellent cell performance like cycle property, and excellent high temperature property. SOLUTION: The nonaqueous electrolyte cell comprises a positive pole, a negative pole capable of occluding and releasing lithium ion, and a nonaqueous electrolyte including lithium ion. The nonaqueous electrolyte is the liquid containing lithium salt and phosphagen derivative shown by the formula; (R1O)3P =N-SO2-R2 [where; R1 represents an alkyl group of 1-10 carbons which may be replaced by halogen atom, or represents the formula; CH3-(OCH2CH2)n-(n is an integer of 1-5) which may be replaced by halogen atom, and R2 represents alkyl group of 1-12 carbons which may be replaced by halogen atom, or phenyl group which may be replaced by halogen atom, alkoxyl group, or alkyl group of 1-4 carbons].

    Abstract: PROBLEM TO BE SOLVED: To improve reliability by preventing moving of a nonaqueous electrolytic battery caused by propulsion force, which is produced when decomposition gas generated is discharged to the outside, at abnormality times. SOLUTION: The battery is composed by storing an electrode body 5, having at least a positive pole 2 and a negative pole 4, and a nonaqueous electrolyte in a closed-end cylindrical armor can 6, wherein an opening of the armor can 6 is closed by a lid body 15. The lid body 15 has a lid part 15a forming a peripheral part of the lid body 15, a projected part 15b which is formed by partially projecting the lid part, and a gas discharging hole 15c drilled at a level difference portion between the lid part 15a and the projected part 15b. A metal plate 18 having a piercing hole is arranged between the lid body 15 and the electrode body 5.
