Abstract: PROBLEM TO BE SOLVED: To enable high energy density to be attained and prevent a poor electric discharge caused by cutting a positive electrode during an electrical discharging operation by a method wherein a breakage extension of the positive electrode current collector is a specified value and an outer diameter of a spiral electrode is a specified rate of an inner diameter of a battery casing. SOLUTION: A nonaqueous electrolyte battery is made such that a spiral electrode composed by laminating and winding a positive electrode 2 and a negative electrode 1 held at both surfaces of a positive electrode current collector 3 of FeS2 or aluminum through a separator 4 is stored in a cylindrical battery casing 5. In this nonaqueous electrolyte battery, a breakage elongation of the positive electrode current collector 3 is restricted to 1.3% to 3.1% and an outer diameter of the spiral electrode is restricted to 97% or more of the inner diameter of the battery casing. With such an arrangement as above, it is possible to prevent a poor electrical discharging caused by cutting the positive electrode during an electrical discharging while a poor insertion of the electrode into the casing, poor making of the positive electrode and reduction of a reaction area of the electrode are being restricted.

Abstract: PURPOSE: To reduce material cost and enhance the reliability of a positive terminal by using a material having austenite and ferrite structure at normal temperature in the positive terminal and fixing a positive electrode to a battery cover or a battery can by caulking. CONSTITUTION: A positive terminal 23 is made of two phase stainless steel comprising austenite and ferrite structure at normal temperature, and enveloped together with a negative electrode 3 and a separator 8. The negative electrode 3, the separator 8, a positive electrode 2, and the separator 8, and the negative electrode 3 are mutually stacked in order to form an electrode stacked body. The positive electrode 2 is fixed to a battery cover 21 or a battery can by caulking. Then they are put in a flat type battery container 10 and an electrolyte prepared by dissolving a lithium salt serving as an electrolyte in an organic solvent is poured in the container 10. Since two phase stainless steel is used and the positive electrode is fixed by caulking, cost is reduced, leakage resistance is ensured to the shock such as falling down, and a battery with high reliability can be obtained.

Abstract: PURPOSE:To prevent a battery from breakage certainly with actuation of an anti- explosion valve by furnishing an electric isulative layer on that surface of valve, at least a part thereof, on the side which receives the battery internal pressure besides the lead connection part. CONSTITUTION:A negative electrode 1 formed by coating a negative electrode current collector 9 with a negative electrode active material and a positive electrode 2 prepared by coating a positive electrode current collector 10 with a positive electrode active material are wound round while a separator 3 is interposed and accommodated in a battery can 5 in the condition that an insulative substance 4 is laid on and under this roll obtained. A positive electrode lead 12 is installed as welded fast to an anti- explosive valve 8 made in aluminum and connected electrically with a battery lid 7 through this valve 8. When the battery internal pressure rises, the valve 8 is heaved to make deformation, and the lead 12 is cut while the part welded to the valve 8 is left. An insulative layer 13 is formed on the surface of valve 8 other than the lead connection part, at least a part thereof, on the side which receives the battery internal pressure. This prevents the battery certainly from temp. rise and breakage.

Abstract: PURPOSE:To ensure a long lifetime even through charge/discharge cycles in a high temp. environment by forming a positive electrode active material so that its cumulative dias. have a specific particle size distribution. CONSTITUTION:A band-shaped positive electrode 2, negative electrode 1, and separator 3 are placed one over another and wound spirally to form a winding, which is accommodated in a battery can 5 with an insulative plate 4 inserted to the bottom. Therein the positive electrode active material applied to the positive electrode 2 has a particle size distribution such that the 10% cumulative dia. is 3-15mum, the 50% cumulative dia. is 8-35mum, and 90% cumulative dia. is 30-80mum. This suppresses deterioration of the electric characteristics due to inclusion of particulates and large-size grains, and drop of the capacity is not likely even when charge/discharge cycles take place in a high temp. environment, and the rate of generation of internal shortcircuit can be lessened. Thereby a battery sustaining service in high temp. environment is achieved, which is also equipped with a high energy density and cyclic characteristics.
