Abstract
A terminal for a Li-ion battery cell utilizes a bimetallic strip formed from the materials used as the Li-ion cell current collectors, such as copper and aluminum. The bimetallic strip is to be used as, at least one, of the Li-ion pouch cell terminals. At least one portion of the bimetallic strip has one of the metallic components removed by such means as chemical or electrochemical etching, mechanical milling, skiving, or grinding, the remaining component being connected to the collector and the other end of the strip serving as the terminal.
