    摘要: A rechargeable alkaline manganese (RAM) battery or battery pack comprising an overcharging protection circuit that allows the RAM battery or battery pack to be charged using a charging circuit designed for use with a different type of rechargeable battery, for example a NiCd or NiMH rechargeable battery. The battery of the present invention is particularly advantageous as a replacement battery for use in devices having an embedded charging circuit designed for use with NiCd or NiMH batteries. The overcharging protection circuit may be provided in a battery pack that allows the individual RAM cells to be removed and replaced. Alternatively, the overcharging protection circuit may be installed in the device itself. When the battery pack is provided as original equipment in an electronic device, an activation key may be provided that prevents discharge of the batteries before the device is used.

    摘要: The present invention relates to electrochemical cells and to closure assemblies for aqueous alkaline electrolyte cells of the conventional cylindrical type. The closure assembly is for the negative terminal and comprises an internal cap disc in unsecured electrical contact with an internal cap ring. When pressure within the cell increases, for example due to gas generation by electrolysis of the electrolyte through abuse or overcharging, the cap disc moves away from the cap ring, breaking the electrical contact and disrupting the electrochemical circuit within the cell. This prevents further gas generation and pressure build-up, thereby preventing a failure of the internal blow out safety vent and escape of the corrosive electrolyte. In time, the pressure dissipates and the cap disc again makes contact with the cap ring, permitting the cell to be used again.

    摘要: A rechargeable manganese dioxide/zinc cell is provided, where the cell has high capacity, high volumetric and gravimetric energy densities, high cycle life, and is capable of continued charge-discharge cycles following an overdischarge. The cell has an aqueous electrolyte, with the usual solute of potassium hydroxide, but the solute may also be a mixture of zinc chloride and ammonium chloride. The electrode balance as determined by the ration of the theoretical discharge capacity of the zinc and the theoretical one electron discharge capacity of the manganese dioxide ranges from greater than 65% up to 110%. On the 15th discharge, a cell of the present invention will deliver a discharge capacity of at least 20% of the discharge capacity delivered on the first discharge. A cell according to the present invention is capable of continued charge-discharge cycles after overdischarge or voltage reversal.

    摘要: In an improved rechargeable alkaline manganese cell that has a manganese dioxide cathode comprising pellets formed by pressing a cathode powder blend comprising a hygroscopic additive for increasing cumulative capacity, the sticky consistency of the pellets, which is un-desirable for continuous automated production is compensated for by the addition of up to 0.5% of a hydrophobic binder. This small amount leaves the cell performance substantially unimpaired, but provides the desired consistency for large-scale production. Further disclosed is an improved charge methodology for a rechargeable alkaline manganese cell wherein the charge current is pulsed at a voltage in excess of 1.65 V and the no-load cell voltage response is monitored at predetermined intervals. No charge current pulse is permitted to pass through the cell if the no-load voltage exceeds a threshold value. This results in increased utilization of the capacity of the cell while reducing the likelihood of damage to the cell due to overcharging.
