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.

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 partcicpates 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： 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 novel electrochemical metal air cells having improved closed circuit voltage characteristics. The improved voltage characteristics are illustrated at a constant load of 51 ohms. The closed circuit voltage during an initial placement into use of the cell of the invention has a decreased voltage drop relative to prior art cells, and recovers to a higher voltage. For example, the closed circuit voltage of the metal air cell drops to a minimum voltage during the first 20 seconds of initial placement into use. The minimum voltage is no more than 22% less than the initial open circuit voltage. This voltage drop is less than the voltage drop of other known metal air cells at 51 ohms. Metal air cells of the invention recover, during the first minute of use, to a closed circuit voltage of at least 79% of the initial open circuit voltage. The value of the open circuit voltage of the metal air cell of the invention is preferably about 1.43 volt.

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： This invention pertains to novel alkaline electrochemical cells having high drain capacities, especially cells having high drain rate capabilities at voltages of at least 1.1 volts for use in small appliances such as hearing aids. The anode includes anode material in the cells including potassium hydroxide, zinc powder, 0.02% to 0.5% indium as indium compound separate from the zinc powder, optionally a low level of mercury, and preferably a surfactant comprising hydroxyethylcellulose. The cathode provides sufficient oxidative capability to oxidize the zinc at a sufficient rate to support the electrical drain demands on the cell. A cathode, in a preferred zinc air cell for a hearing aid, includes at least 5 air ports, evenly distributed over the surface of the bottom of the cathode can. Cells of the invention exhibit prolonged operation at relatively constant voltage over 1.1 volts, and relatively constant power output at a power density of at least about 210 milliwatts per square inch of the reaction surface area of the cathode assembly, for periods significantly longer than conventional cells.
