    摘要： An alloy capable of reversibly absorbing and desorbing lithium ions in a non-aqueous electrolyte containing lithium ions on charging and discharging has excellent applicability to anode for rechargeable electrochemical devices. However, such alloy, when absorbed with lithium, loses its flexibility, so that when it is incorporated in a device in a charged state, it is subject to trouble such as cracking and can not display its properties. This invention adopts a method in which anode alloy is combined with lithium by connecting them so as to be electronically conductive to each other and this combination is fitted into the device, and then the electrolyte is supplied into the device to have lithium absorbed in anode alloy in the device. According to this method, cracking of cathode can be prevented.

    摘要： The invention relates to a new method of manufacturing a sealed rechargeable alkaline battery including metal oxides as positive electrode active materials and a hydrogen absorbing alloy as a negative electrode material. The basic principle of the method is that, instead of the conventional electrochemical formation, the property of a hydrogen absorbing alloy is utilized to cause the negative electrode to absorb hydrogen to thereby achieve precharged portions within the negative electrode having a relatively larger capacity as compared with the positive electrode. Regardless of the kind of positive electrode, the method of the invention insures a broad freedom in the capacity appropriation between the positive and negative electrodes.

    摘要： A rechargeable negative electrode for an electrochemical apparatus using nonaqueous electrolytes, said electrode comprising an alloy comprising (1) at least one metal selected from the group consisting of Sn, Pn, In and Bi and (2) Zn or Zn and Cd, as well as a rechargeable electrochemical apparatus comprising a combination of said negative electrode with a positive electrode having reversibility in charging and discharging. The above-mentioned negative electrode reversibly absorbs and desorbs alkali metal ions, as the result of charge and discharge, in nonaqueous electrolyte containing alkali metal ions. It undergoes no pulverization even after repeated charge and discharge, and maintains its shape stably, so that it has a long charge-and-discharge cycle life. Further, since it can absorb a large quantity of alkali metal per unit volume, it is of high energy density.
