    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: 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: 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.
