Date Oct. 11, 1984.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.
