摘要： A seal tab consisting of an acrylic adhesive applied to a biaxially-oriented three-ply synthetic paper of polypropylene is used as a sealing means for metal-air electrochemical cells, and batteries constructed thereof. The seal tabs prevent loss of rate capability and capacity due to interactions with the surrounding environment prior to the placement into service of metal air cells, yet without so isolating the cells such that the initial open circuit voltage is deemed unacceptable by the end user. Additionally, the seal tab, as provided, is easily and cleanly removed, which enhances the cell's consumer appeal.
摘要翻译： 作为用于金属 - 空气电化学电池的密封装置和由其构成的电池，使用由应用于聚丙烯的双轴取向三层合成纸的丙烯酸类粘合剂构成的密封片。 密封片防止在金属空气电池投入使用之前由于与周围环境的相互作用而造成的速率能力和容量的损失，但是没有隔离电池，使得初始开路电压被最终用户认为是不可接受的。 另外，如所提供的那样，密封片容易且干净地移除，这增强了电池的消费者吸引力。

摘要： A metal current collecting substrate for an air cathode in an electrochemical metal air cell is provided for, wherein the substrate is hardened by one of the steps of sandblasting, shotblasting, plastic deformation of the substrate below the recrystallization temperature range of the metal thereof, and heating the substrate to above the transformation temperature of the metal thereof followed by quenching the substrate below the transformation temperature of the metal thereof. Catalytically active materials, most preferably a mixture of carbon and manganese dioxide, are pressed or otherwise disposed upon the hardened substrate. The substrate is capable of being connected to electrical circuitry. Most preferably, the substrate is a metal screen that has been hardened, roughened and pitted by sandblasting before the catalytically active materials are disposed thereupon, and before the substrate is incorporated into an electrochemical metal air cell.

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. The seal disposed between the anode can and the cathode can is made thinner. Structure of the corner of the cathode can between the bottom and the side wall is improved. 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： A system and method are provided for rapidly evaluating electrochemical components such as catalysts, electrodes, electrolyte, and membranes that delivers a high degree of accuracy and requires minimal materials costs. In one embodiment, the system may comprise a detachable electrochemical cell for housing an electrochemical reaction. The cell may comprise an anode chamber and a cathode chamber separated by an ion-diffusion membrane and an electrically conductive current collector in electrochemical communication with the cell. The reaction cell includes an outlet port in the cell to permit the removal of product gasses, and ports to permit the flow of electrolyte through said cell. The system further comprises means, for example, a reciprocating piston, for sealing the reaction cell to the system to prevent exposure of the electrochemical reaction to the ambient environment, where the cell and adjacent components may be sealed by, for example, gaskets, that permit rapid separation.
