Also, in 1996 Patent Application No. 91468, the applicant has clarified a button type alkaline battery using a mold in which ceramics are arranged at least in a portion in contact with Cu and a manufacturing method thereof in manufacturing a negative electrode can.
They were superior to the negative electrode cans manufactured with a mold using cemented carbide or tool steel before that. However, the material itself has not been sufficiently treated against the adhesion of metals that would deteriorate the quality of the battery if it penetrates into the battery.

いる。Problems to be Solved by the Invention A negative electrode can manufactured by a conventional method has a problem that, depending on the material lot, even if ceramics are used in a mold for processing the material into a can.
When Zn, which is the negative electrode active material, and the alkaline electrolyte contact the Cu surface of the can, a part of the electrolyte solution is decomposed and gas may be generated from the Cu surface. The reason for this is that the metal that has deteriorated the quality of the battery has already adhered to the inside of the battery when the material is rolled. The material is mainly rolled by using a roll made of cemented carbide, but Co or N used as a binder for the cemented carbide.
i, W, which is the base material of the cemented carbide, is transferred, though a small amount, during the processing of the material of the negative electrode can, and the Cu surface on the inner surface of the negative electrode can is formed as it is attached. is there. This gas generation leads to exhaustion of the negative electrode mixture in the button type alkaline battery, which deteriorates the self-discharge characteristics of the battery.

る。It is considered that the material varies from lot to lot because the cemented carbide does not wear uniformly over time, but the wear progresses rapidly when the surface fatigue of the roll reaches a certain value. . There is also a method of chemically polishing a completed negative electrode can, but it is very expensive and extremely disadvantageous in industry.

まれる水銀による環境汚染の懸念がある。When mercury is contained in the negative electrode mixture, the degree of gas generation is reduced by covering the Cu surface with the mercury, so that the gas generation can be suppressed, but it depends on the mercury contained in the discarded battery. There is concern about environmental pollution.

は（１）と同一である。Therefore, the present invention prevents adhesion of unfavorable metals to Cu on the inner surface of the negative electrode can by using one of the following three methods. (1) After rolling the material of the negative electrode can with Cu on one side,
A step of removing the surface by chemical polishing and providing an anticorrosion treatment is provided, and then a negative electrode can having Cu as an inner surface is at least C
The portion that contacts the u-face is a ceramic mold, and is molded and processed. (2) Electrochemical polishing was performed instead of the chemical polishing described above. The subsequent steps are the same as in (1). (3) The surface of the roll itself for rolling the negative electrode can material was coated with ceramics to prevent metal from adhering to the Cu surface of the negative electrode can material during rolling. There are many types of ceramics that can be used for coating, but zirconium oxide, silicon boride, silicon nitride, or carbon with a diamond-like structure is preferred. The process of molding and processing the negative electrode can is the same as (1).

研磨処理を連続的に行うことに適している。The chemical polishing of the negative electrode can material is a cold-rolled strip itself and can be continuously processed, and the cost of chemically polishing the completed negative electrode can is not incurred.
Further, the electrolytic polishing is suitable for continuously performing the polishing treatment on the surface of the material such that the treatment liquid is less deteriorated and the polishing amount can be controlled by the current value.

る。When the surface material of the rolling roll is changed to ceramics, it is necessary to control the wear of the coated ceramics, but it is not necessary to carry out chemical polishing, electrolytic polishing or the like later. The wear of ceramics can be controlled by the electric resistance value between the roll and the work.

使用する。BEST MODE FOR CARRYING OUT THE INVENTION The present invention is particularly suitable for producing a button-type alkaline battery using low mercury or mercury-free zinc as a negative electrode mixture, by cooling a trace amount of metal attached to the Cu surface of a negative electrode can material. After sufficient removal at the stage of hot rolling, the inner surface is Cu
The molding and processing of the negative electrode can is carried out by processing with a metal mold of at least a portion contacting the Cu surface. More preferably, a die in which a ceramic coating is applied to the surface of a cemented carbide or steel at the portion in contact with the Cu surface of the material is used.

適切である。The minute amount of metals adhering to the Cu surface of the negative electrode can material is removed by chemical polishing or electrolytic polishing. Alternatively, a rolling roll coated with ceramics is used to prevent metals from adhering during rolling. Suitable ceramics for coating the roll are zirconium oxide, silicon boride, silicon nitride, carbon having a diamond-like structure, and the like.

らない。When chemical polishing or electrolytic polishing is performed, the material is subjected to surface rust prevention treatment. This is because the surface of the material is oxidized and copper oxide is generated without the rust-preventing treatment, but the copper oxide has an unfavorable effect in the battery, like the case where foreign metals adhere. When a negative electrode can which is formed and processed using a die in which ceramics are arranged at least in a portion in contact with the Cu surface using such a material, Fe from steel,
Transfer of trace amounts of Co, Ni, W, etc. from cemented carbide does not occur.

著である。Therefore, the amount of gas generated when the negative electrode can of the present invention is brought into contact with the negative electrode mixture and the alkaline electrolyte is greatly reduced as compared with the conventional case. The effect of reducing gas generation is particularly remarkable when negative electrode zinc containing little or no mercury is used.
