摘要： PROBLEM TO BE SOLVED: To provide a manganese dry cell having good liquid leakage resistance without complicating manufacturing processes. SOLUTION: In the manganese dry cell with its opening of a negative electrode zinc can taking in generating elements closed by a positive electrode terminal block which is inserted into a sealing body of synthetic resin and a carbon rod, a ring shaped lobe is set on a brim of the sealing body towards the positive electrode terminal block, which fastens a thermal shrinkage tube covering the brim of the sealing body from a side surface of the zinc can with the positive electrode terminal block and the sealing body. With this, even when gas is generated at over-discharging and electrolyte solution crawls up on the sealing body, the electrolyte solution does not leak outside of the cell, thus, a dry cell having good liquid leakage resistance is obtained.

摘要： PURPOSE:To prevent increase of resistance between an output terminal and a lead member by working a rivet member insertion hole of the lead member into a protrusion beforehand and enabling the output terminal part of a battery to attain a closer rigid caulking state. CONSTITUTION:In a caulking connection member 13 for both a rivet member 7 and a lead member 12, a rivet member insertion hole of the lead member 12 is protrusively wrought in advance. Thereby since a shape of a caulking part of the rivet member 7 is caulked so as to fit in with a shape of the rivet member insertion hole of the lead member 12, an area of a contact part between the lead member 12 and the rivet member 7 enlarges. In addition to this, when the caulking work is performed with the rivet member 7, the rivet member insertion hole of the lead member 12 is caulked so as to bite into a rivet member insertion hole of a terminal assembly 10. As a result, in an output terminal part of a battery, a closer rigid caulking state can be attained and increase of resistance between the output terminal 8 and the lead member 12 can be prevented especially under a preservation condition of high temperature and high humidity.

摘要： PURPOSE:To stabilize the performance of an alkaline manganese battery by forming a battery case also serving as a current collector by drawing a nickel- plate steel plate to form a case and then replating the entire surface of the case. CONSTITUTION:In an alkaline manganese battery containing a positive mixture 2, a separator 3 and a gelling negative zinc 4, a battery case 1 also serves as a current collector. The battery case 1 is completed by drawing a steel plate at least one surface of which is plated with nickel to form a case the inner surface of which consists of the nickel plating surface and then replating the entire surface of the case. As a result, cracks and separation of the nickel layer of the case surface can be repaired by replating, thereby preventing any troubles which might be caused by corrosion. Furthermore, the positive mixture 2 can be favorably brought into close contact with the case 1.

摘要： PURPOSE:To increase the preservation performance of a battery by using graphitized carbon, which is prepard by subjecting a coke to a given treatment, as a conductive material for a positive mixture. CONSTITUTION:A positive mixture contains a conductive material made of graphitized carbon, which is prepared by subjecting a coke to heat treatment carried out in a nonoxidizing atmosphere. The former graphitized carbon is obtained by heating a coke up to near 3,000 deg.C in a nonoxidizing atmosphere. As the coke, petroleum coke, coal coke, pitch coke or the like is used. Since thus prepared graphitized carbon exibits enough flowability and lubricating property like natural flake graphite does when the positive mixture is subjected to dry molding, and any impurity such as Cu, Pb or Cd, which penetrates a separator and causes short circuit between a positive and a negative electrode, is not contained in the positive mixture, the preservation performance of a battery can be increased. It is preferable, especially, that the former graphitized carbon is used as a conductive material for a manganese dioxide which is used as an active material, is manufactured by electrolytic method and contains almost no impurities.
