摘要： An electrochemical cell having a high capacity is described. The cell capacity can be increased by a method of selecting cell components to achieve particular volume ratios within the cell. Specific volume ratios that lead to improved capacity include the ratio of the internal cell volume to the external volume, the ratio of the closure volume to the external volume, the ratio of the closure volume to the internal cell volume, the ratio of the seal volume to the internal cell volume, and the ratio of the seal volume to the external volume.

摘要： The invention is directed to a pressure activated current interrupt assembly for cells, particularly alkaline cells. The current interrupter is located at the closed end of the cell's housing. The current interrupter assembly comprises an electrically insulating member in proximity to the terminal at the closed end of the housing. The insulating member is in physical communication with a deflectable member formed from the cell's housing. When gas pressure within the cell builds up to exceed a predetermined value, the deflectable member deforms causing the insulating member to protrude beyond the extremity of said cell terminal, thereby preventing electrical contact between said terminal and the terminal of another cell or electrical device.
摘要翻译：本发明涉及用于电池，特别是碱性电池的压力启动电流中断组件。电流断路器位于电池壳体的封闭端。电流断续器组件包括在壳体的封闭端附近靠近端子的电绝缘构件。绝缘构件与由电池壳体形成的可偏转构件物理连通。当电池内的气体压力超过预定值时，可偏转构件变形使得绝缘构件突出超过所述电池端子的末端，从而防止所述端子与另一电池或电气装置的端子之间的电接触。

摘要： An electrochemical separator is formed insitu on an electrode surface within an electrochemical cell, preferably an alkaline cell cathode surface. The alkaline cell comprises a zinc anode, a and potassium hydroxide electrolyte. The cathode may comprise a cathode comprising manganese dioxide. The separator may be formed by coating an electrode surface preferably with a low molecular weight copolymer of polyvinyalcohol and polyvinylacetate. The film can be coagulated to form a permeable separator uniformly conforming to and covering the electrode surface irrespective of the shape and contour of the electrode. A separate protector disk can be inserted onto the top surface of the cathode to protect the cathode from shorting in the event that imperfections in the separator surface develop. The protector disk can have a protruding lip which surrounds and protects the inside corner edge of the cathode.
摘要翻译：在电化学电池，优选碱性电池阴极表面中的电极表面上形成电化学分离器。碱性电池包括锌阳极，氢氧化钾和氢氧化钾电解质。阴极可以包括包含二氧化锰的阴极。隔膜可以通过优选用聚乙烯醇和聚乙酸乙烯酯的低分子量共聚物涂覆电极表面而形成。不管电极的形状和轮廓如何，可以使膜凝结形成均匀地均匀地覆盖电极表面的可渗透分离器。如果分离器表面的缺陷发展，则可以将独立的保护盘插入阴极的顶表面，以保护阴极免于短路。保护盘可以具有突出的唇缘，其围绕并保护阴极的内角部边缘。
