Abstract: PURPOSE:To manufacture a resin board superior in thickness accuracy, by a method wherein tightening force of a cell is made force wherein a leaking quantity of resin to be cast becomes a specific value. CONSTITUTION:A gasket having a thickness whose difference from a mean thickness to be obtained by dividing volume of resin to be cast which is cast into a cell by an area surrounded by the gasket is within + or -5% is used and a resin board is obtained by making tightening force into a force wherein a quantity of leakage of the resin to be cast becomes less than 5 capacity % by exceeding 0 capacity %. With this construction, a deformation of the gasket in a thickness direction is mitigated, a phenomenon wherein the central part of the resin board becomes thick and a section becomes a drum form by a method wherein a deformation in a thickness direction of the gasket becomes high at the time of molding can be controlled, through which the resin board superior in thickness accuracy is obtained.

Abstract: PROBLEM TO BE SOLVED: To generate outside short-circuiting before a current collector disposed inside is short-circuited due to a physical shock from the outside so as to prevent any breakage and firing of a battery by disposing insulative separate substance around a battery jar. SOLUTION: Insulative separate substance 13 is disposed around a battery jar 5 serving as a negative electrode terminal. On the substance 13, a conductor 14 of metallic material or carbonaceous material is laminated in contact with a portion of a battery cover 7. The separate substance 13 keeps insulation from the conductor 14, and rapidly brings the battery jar 5 and the conductor 14 into contact with each other in the case where the battery jar 5 receives a shock from the outside to such an extent to be deformed the battery jar 5. When a battery is exposed under high temperature, the separate substance 13 is fused, so that the battery jar 5 and the conductor 14 are brought into contact with each other, thereby releasing energy. Consequently, even if these is a physical shock to such an extent to deform the battery jar 5, outside short- circuiting is forcibly generated before a current collector disposed inside is short-circuited, thus reducing and preventing breakage and firing of the battery.

Abstract: PROBLEM TO BE SOLVED: To provide an electrode for a battery with high adhesion of a binder with a current collector and capable of increasing the thickness of an electrode material by limiting each modulus of elasticity in bending, compression, and tension of binder resin. SOLUTION: A binder containing resin having a modulus of elasticity in bending of 1000MPa or less and/or modulus in compression of 500MPa or less and/or modulus of elasticity in tension of 500MPa or less is used in the binder of an electrode for a battery. The binder containing the resin increases the flexibility of the electrode and coating capability, and is especially effective when the electrode is spirally wound. Since the flexibility is increased, the thickness of the electrode can be increased, the filling amount of an active material is increased to increase the capacity. The content of the resin in the binder is 5% or more by weight, and the resin is preferable to be fluorine resin, especially polyhexafluoropropylene and/or a copolymer of vinylidene fluoride and hexafluoropropylene.
