ABSTRACT:
In a battery comprising a spirally wound electrode group, a lead plate drawn from one electrode of the electrode group and connected to the inner bottom surface of the battery case in electrically conducting relationship, and an insulating plate interposed between the lead plate and the electrode group, at least the bottom surface of the insulating plate is formed from a heat weldable material, and the lead plate is heat-welded to this heat weldable material. This construction not only serves to completely prevent accidental short-circuiting, but enables high-speed assembling of batteries.
