摘要： A conventional bipolar battery is constituted of a combination of cells hermetically sealed for preventing a liquid junction and preventing corrosion of a peripheral device due to a liquid leakage. Therefore, electrolytic solution injecting processes are carried out as many as the number of cells, so that much times and costs have been required for manufacturing a large-scale battery. In addition, a wiring space has been required since the cells are connected to one another with wires. The use of a current collector formed of a one-end closed tubular conductor, the current collector having a bottom protruding outward to form a protrusion, eliminates the wiring space and achieves a reduction in ohmic loss due to the wires. In addition, an electrolytic solution in one cell is separated by a water-repellent sheet from an electrolytic solution in another cell, so that a liquid junction is prevented.

摘要： Carbon or cobalt, which is used as a conductive agent in an electrode of an alkaline secondary cell, is oxidized by oxygen generated from a positive electrode. The conductive agent degraded by oxidization loses its conductivity through repetitive charge and discharge, resulting in shortening of the cycle life of the cell. In an alkaline secondary cell filled with hydrogen, hydrogen generated from a positive electrode is bound to the hydrogen. This prevents a conductive agent in an electrode from being degraded by oxidization. A cell with excellent cycle life characteristic is thus provided.
摘要翻译：在碱性二次电池的电极中用作导电剂的碳或钴被由正极产生的氧氧化。通过氧化降解的导电剂通过重复的充放电而失去其导电性，导致电池的循环寿命缩短。在充满氢的碱性二次电池中，由正极生成的氢与氢结合。这防止了电极中的导电剂被氧化降解。因此提供了具有优异的循环寿命特性的电池。
