Abstract
A sealed battery including an electrode assemblyhaving multiple positive electrode substrates exposed at one end and negative electrode substrates exposed at the other end; and collectorsand collector receiving partsthat are resistance-welded on both sides of the multiple positive or the multiple negative electrode substrates or both, a through-holebeing formed in at least one of the collectorsand the collector receiving parts, and the resistance welding being performed at the rim of the through-hole. With such sealed battery, the spattered particlesgenerated during the resistance welding are captured in the through-hole, and will rarely enter the interior of the electrode assemblyor splash out to the exterior.
