    • 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.

    • 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.
