Abstract
The present application discloses a battery comprising a collector rod serving also as a winding core and having at one end thereof a non-circle shape flange, positioning means formed at the flange, a spiral electrode formed by band-shape positive and negative electrode plates with a separator layer therebetween wound upon the collector rod with one of the electrode plates electrically connected to the collector rod, a battery vessel for housing the spiral electrode and to which the other of the electrode plates being electrically connected, a lid for hermetically closing the opening of the battery vessel through insulating packing and for simultaneously forming a terminal of said one electrode plate, and conductive resilient means having one end positioned by the positioning means and the other end in contact with the lid so that the conductive resilient means is pressed by the flange and the lid to electrically connect the collector rod and the lid to each other. The provision of the non-circle shape flange at one end of the collector rod serving also as a winding core, facilitates the winding operation of positive and negative electrode plates upon the collector rod, whereby the…
