摘要： PROBLEM TO BE SOLVED: To provide a lithium secondary battery which exhibits superior safety at overcharging. SOLUTION: This lithium secondary battery is provided with an electrode body comprising a positive electrode and a negative electrode laminated via a porous separator, a nonaqueous electrolyte comprising organic solvent and an electrolyte dissolved therein, and a battery case which stores the electrode body and the nonaqueous electrolyte. The electrolyte in the nonaqueous electrolyte is constituted so as to be composed of LiClO4 and second lithium salt exclusive thereof. The separator is softened and blocked up by the heat induced by LiClO4 in the early stage of overcharging and charging current is shut down, and the temperature rise due to rapid chain reaction can be avoided and an overcharging state is settled.

摘要： PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte solution battery with high safety by forming terminal structure capable of preventing or restraining a spark which may be generated in a terminal portion caused by leakage of nonaqueous electrolyte solution.
SOLUTION: The nonaqueous electrolyte solution battery 1 which has a structure having a battery case 20 made from metal, outer terminals 30b, 40b insulated therefrom, and fix member 32, 33, 42 and 43 fixing the outer terminals is so constituted that the outer terminal 30b existing in at least positive side is formed from aluminum alloy material and its fix member 32, 33 is formed from aluminum alloy material or electrical insulating material. Even if the nonaqueous electrolyte solution leaks in its portion B to form a bridge, an active radical promoted by the ionization of transition metal is less generated and an organic catalyst is restrained to dissociate, and thus the spark is prevented or restrained.

摘要： PROBLEM TO BE SOLVED: To provide a secondary battery and its manufacturing method for appropriately performing degassing from a rolled electrode and preventing ignition.
SOLUTION: A passage 41 extending from a center section 3c of a rolled electrode 3 to open on an outer peripheral face section 30 is composed of holes formed on a positive electrode sheet and a negative electrode sheet and small holes disposed at a separator. When a gas is generated at the center section 3c of the electrode 3 in over charge etc., the gas is discharged on a side opposite to a safety valve through the passage 41, then exhausted from the safety valve 5 after moved to the safety valve 5 from the discharge section. Since the energy of a spark generated due to short circuit becomes small by reaching the safety valve 5, it is possible to avoid a situation that may occur in a conventional technology, in which the positive sheet and the negative sheet of the electrode 3 just under the safety valve 5 are burst up. A fire source (A spark, a fire column, a flame) is suppressed to be blasted out outside a battery case 2 and the ignition accompanied by blasting out of the fire source can be evaded.

摘要： PROBLEM TO BE SOLVED: To provide a discharge mechanism that rapidly discharges electric charge accumulated in a smoothing capacitor. SOLUTION: When an external force F is applied to input cables 1, 2 and these input cables 1, 2 are pressed to the rear side, the input cables 1, 2 are pressed toward the side of a short-circuiting metal fitting 2100. As a result, the input cables 1, 2 contact the short-circuiting metal fitting 2100, so that the external force F is applied to the short-circuiting metal fitting 2100. Thereby, the ends of contact portions 2120, 2120 of the short-circuiting metal fitting 2100 move in the direction of getting close to a first terminal T1 and a second terminal T2, so that the short-circuiting metal fitting 2100 contacts the first terminal T1 and second terminal T2. Consequently, the first terminal T1 and second terminal T2 are put into a short-circuited state, which discharges the electric charge accumulated in the smoothing capacitor.

摘要： PROBLEM TO BE SOLVED: To provide a secondary battery having a function preventing burst release of energy stored in the battery at one time when the battery is overcharged. SOLUTION: This secondary battery 1 is formed by housing a wound electrode body 10 in a flat case 20. The electrode body 10 is formed by stacking a positive electrode sheet, a negative electrode sheet, and a separator, and winding them. Both sides in the thickness direction of the electrode body 10 come in contact with the inner walls of the maximum flat parts 201, 202 of the case 20. The maximum flat parts 201, 202 are interposed between restriction plates 32 of an outside support 30. A swell suppressing member 40 suppressing the swelling of the electrode body with the case 20 and the outside support 30 is installed. When the electrode body 10 is swollen by overcharging, compression stress P2 is applied to the electrode body 10 against swelling force P1. An electrode active material is penetrated in pores of the separator by the compression stress, minute short circuits are generated between the positive electrode and the negative electrode. Thereby, energy stored by overcharging is gradually released.
