Battery, method of manufacturing the same, method of manufacturing weldment, and pedestal

摘要

A metal plate and an electrode in a polymer lithium ion secondary. battery or the like are welded certainly, and it is accomplished to further improve the reliability and the durability thereof. Each of an upper metal plate ( 7 a) and a lower metal plate ( 9 a) on the positive pole/terminal is welded to a pole/terminal of positive electrode ( 3 ) so that the pole/terminal of positive electrode ( 3 ) may be sandwiched from each of the upper and lower sides. Moreover, each of an upper metal plate ( 7 b) and a lower metal plate ( 9 b) on the negative pole/terminal is welded to a pole/terminal of negative electrode ( 5 ) so that the pole/terminal of negative electrode ( 5 ) may be sandwiched from each of the upper and lower sides. This eliminates occurrence of poor welding in the electric resistance welding.
