    摘要： A nickel-hydrogen battery is designed to have, in its battery container, electrode plates welded and connected onto a lead conductor. With the configuration, the edge of the end portion of the lead conductor welded onto the electrode plate can be formed as a combination of concave and convex portions. The stresses on the electrode plate and lead conductor are concentrated on the edge of the end portion onto which the electrode plate and lead conductor are welded and where a crack may arise. However, shaping into waveform the edge of the end portion where the lead conductor is welded onto the electrode plate makes the edge of the end portion long enough to reduce the concentration of the stresses. Furthermore, even if the crack may have arisen, the development of the crack can be reduced by making the crack development direction different from the direction of the edge of the lead conductor because the edge of the end portion of the lead conductor is shaped into waveform.
