    摘要： A conventional battery has a problem that a large short-circuit current is generated with temperature rise due to internal short-circuit, and therefore, the temperature of the battery further increases due to heat and the short-circuit current is increased. Also, there is a problem in safety that the sealed part can be easily opened with temperature rise in case of using the aluminum laminated bag as the outer body for sealing the battery body. The present invention has been carried out in order to solve the above problems. The battery of the present invention is a battery wherein at least one of the positive electrode 1 and the negative electrode 2 comprises the active material layer 6 containing the active material 8 and the electronically conductive material 9 contacted to the active material 8; wherein the battery body 11 is constructed by containing the electrolytic layer 3 between the above positive electrode 1 and negative electrode 2, and the above battery body is sealed with the outer body 14 comprising the aluminum 13 and the thermal fusion resin 12; and wherein the electronically conductive material 9 comprises the electrically conductive filler and the resin so that the resistance increases in accordance with temperature rise.

    摘要： This invention pertains to alkaline electrochemical cells, typically to metal-air cells of the button-type. Non-reactive elements of cells of the invention are thinner than corresponding non-reactive elements of prior art cells. Such elements can be made thinner because of improved structures of such elements. The anode can is made from a metal strip structure having a higher steel content. The cathode can has a modified temper, which improves relative stiffness and rigidity while retaining sufficient ductility. By so reducing the thicknesses of non-reactive elements of the cell, and thus the volume occupied by such non-reactive elements, the fraction of the cell devoted to holding electrochemically reactive anode material therein is increased, with corresponding increase in the milliampere hour capacity of the cell.

    摘要： This invention pertains to electrochemical cells, and anode cans used therein, wherein edge regions of respective anode cans are toed-in. The anode can includes a top wall, and a first side wall depending downwardly from the top wall. The first side wall has an edge region remote from the top wall. The cathode can has a bottom wall, and a second side wall extending upwardly from the bottom wall. The edge region of the first side wall is displaced inwardly of the outer surface of the first side wall as defined at locations away from the edge region. Thus, the edge region is toed-in. Generally, the first side wall follows a path from an intermediate element of the first side wall to a distal edge of the first side wall, wherein no element of the path is directed toward the top wall. The invention further comprehends methods of making the above metal anode cans, and cells.

    摘要： This invention pertains to metal-air electrochemical cells wherein one or more air entry ports is located in the bottom of the cathode can, to provide for entry of oxygen-rich air into the cathode can, where the oxygen participates in the chemical reaction whereby the cell produces electrical energy. In this invention, multiple small air entry ports are provided. Generally, the use of multiple ports distributed over the bottom of the cathode can, opposite the reaction surface of the cathode assembly, while not increasing the overall open area of the ports, results in an increase in the ratio of the cell limiting current to the rate at which moisture is lost from the cell. Accordingly, moisture loss as a function of electrical energy produced, is less.

    摘要： The performance characteristics of alkaline batteries are improved by applying a thin, polymeric coating to the inner surface of a positive current collector. The polymeric coating comprises, in combination, a first film forming binder component and a second component comprising an electrically conductive filler such as carbon. The coating reduces the internal resistance of a battery, and may even be used on unplated steel.
