摘要： Disclosed is a negative electrode for an alkaline secondary battery, which can suppress elution of iron to improve the long-period storage property of the battery capacity even under conditions in which elution of iron in a substrate into an electrolyte solution tends to occur, and which can also suppress lowering of initial capacity and increase in internal resistance. Even under conditions in which the elution of iron in the substrate into an electrolyte solution tends to occur, including a case where there is a thin conductive protecting layer at the surface or where the conductive protecting layer has defects, by adding magnesium or a magnesium compound to the negative electrode for an alkaline secondary battery (excluding the case where magnesium is contained as a constituent element of a hydrogen storage alloy), the elution of iron can be suppressed, and thereby, the long-period storage property of the battery capacity can be improved and the lowering of the initial capacity and the increase in internal resistance can be suppressed.

摘要： Provided are sealed pouch-cell batteries that are alkaline batteries or non-aqueous proton-conducing batteries. A pouch cell includes a flexible housing such as is used for pouch cell construction where the housing is in the form of a pouch, a cathode comprising a cathode active material suitable for use in an alkaline battery, an anode comprising an anode active material suitable for use in an alkaline battery, an electrolyte that is optionally an alkaline or proton-conducting electrolyte, and wherein the pouch does not include or require a safety vent or other gas absorbing or releasing system as the anode active material and the cathode active material do not increase the internal atmospheric pressure any more than 2 psig during cycling. The batteries provided function contrary to the art recognized belief that such battery systems were impossible due to unacceptable gas production during cycling.

摘要： A hydrogen storage method is provided which enables a hydrogen storage alloy to store hydrogen up to a maximum hydrogen storage amount thereof in excess of a generally known theoretical value. In a hydrogenation step, a hydrogen storage ratio calculated as an atomic weight ratio between hydrogen and the hydrogen storage alloy is obtained beforehand as a theoretical value, a pressure at which the hydrogen storage alloy stores hydrogen up to the theoretical value is set as a first pressure value, a pressure value ten or more times greater than the first pressure value is set as a second pressure value, and pressure is increased up to the second pressure value. In a dehydrogenation step, the pressure is decreased from the second pressure value to or below the first pressure value. The hydrogenation step and the dehydrogenation step are repeatedly executed.
