Title: (EN) MANUFACTURING METHOD FOR ALKALINE MANGANESE BATTERY
(JA) アルカリマンガン電池の製造方法
Abstract: front page image
(EN) PROBLEM TO BE SOLVED: To provide a manufacturing method for an alkaline manganese battery having high productivity and high capacity, capable of aiming at reduction of an uneven amount of liquid absorption and increase in the amount of liquid absorption of an alkaline electrolyte, by effectively accelerating liquid absorption of the alkaline electrolyte to a positive electrode mixing agent.

SOLUTION: The manufacturing method for the alkaline manganese battery includes a liquid pouring process of inserting a plurality of cylindrical positive electrode mixing agents 2A, 2B into a battery case 1, with an arrangement of overlapping each other and pouring a designated amount of the alkaline electrolyte 7 into a space inside a cylindrical separator 4, after inserting the cylindrical separator 4 inside respective positive electrode mixing agents 2A, 2B; a first liquid-absorption process 41 of rapidly air-opening the inside of a chamber 23 storing the battery case 1, after gradually decompressing the chamber 23 to a designated vacuum level; and a second liquid-absorption process 42 of gradually air-opening the chamber 23, after gradually decompressing the inside of the chamber 23 storing the battery case 1 to a designated vacuum level, after completing the first liquid-absorption process 41.

【課題】アルカリ電解液の正極合剤への吸液を効果的に促進させることにより、アルカリ電解液の吸液量のばらつきの低減と吸液量の増大とを図って高い生産性で高容量のアルカリマンガン電池を製造することができる方法を提供する。
【解決手段】電池ケース１内に複数個の筒状の正極合剤２Ａ，２Ｂを互いに重ねた配置で挿入し、各正極合剤２Ａ，２Ｂの内側に筒状セパレータ４を挿入したのち、筒状セパレータ４の内側の空間に規定量のアルカリ電解液７を注入する注液工程と、電池ケース１を収容したチャンバー２３の内部を所定の真空度まで緩やかに減圧したのちに急激に大気開放する第１の吸液工程４１と、第１の吸液工程４１の終了後に、電池ケース１を収容したチャンバー２３の内部を所定の真空度まで緩やかに減圧したのちに緩やかに大気開放する第２の吸液工程４２とを有している。
