SECONDARY BATTERY AND ELECTRODE MEMBER THEREOF, BATTERY MODULE, AND RELATED APPARATUS

A secondary battery and an electrode member thereof, a battery module, and a related apparatus are provided. The electrode member includes a current collector, an active material layer, an adapting sheet, and an electrode lead. The current collector includes an insulating substrate, a first conductive layer, and a second conductive layer. The first conductive layer and the second conductive layer each include a coated region and an uncoated region, the coated region is coated with an active material layer, and the uncoated region is not coated with an active material layer, a size of the current collector in a length direction is larger than that in a width direction, and the uncoated region is located on a side of the coated region in a length direction. The adapting sheet includes a first conductive member and a second conductive member.
