Abstract
A current collector for a lithium ion battery of reduced sensitivity to shocks and jars includes an insulating substrate, a first conductive layer; and at least one extended conductive layer extending from the first conductive layer. The insulating substrate has a main region and at least one tab region extending therefrom. The main region includes first and second surfaces opposing each other. The tab region includes a first extended surface extending from the first surface, and a second extended surface extending from the second surface. The first conductive layer covers the first surface, and the at least one extended conductive layer covers the first extended surface. Each tab region and extended conductive layer form a tab. The disclosure also provides an electrode plate and an electrode assembly.
