CURRENT COLLECTOR TERMINAL PLATE FOR SECONDARY BATTERY, SECONDARY BATTERY, AND METHOD FOR PRODUCING SECONDARY BATTERY

摘要

A current collector terminal plate comprising a plate-shaped conductive material is used. The conductive material has an expected welding portion that melts with priority. The conductive material has, for example, a bent portion forming a protrusion on one side and a depression on the other side and a flat portion, and the expected welding portion includes the bent portion. The bent portion has a pair of upstanding portions raised from the flat portion and a bent top portion extending continuously from the pair of upstanding portions.
