ABSTRACT:
In a method of manufacturing a spiral electrode assembly, a first electrode member of one polarity is covered with a separator, and the separator is extended forward beyond the leading end of the first electrode member to form an extension consisting of the separator only. This separator extension is inserted into a slot formed in a spool and is wound around the spool. After the separator extension has been wound by the length more than the length of the circumference of the spool, a second electrode member of opposite polarity is inserted in such a relation that the leading end of the first electrode member is located rear relative to that of the second electrode member. The spool is rotated to wind the two electrode members separated by the separator therearound, and the spool is then withdrawn to provide the spiral electrode assembly.
