Abstract

The present disclosure relates to the technical field of battery, and in particular, relates to a current collector, an electrode plate including the current collector, and an electrochemical device. The current collector includes an insulation layer; and a conductive layer at least located on at least one surface of the insulation layer. The conductive layer has a room temperature thin film resistor of R, where 0.01Ω/□≤R≤0.15Ω/□. The current collector is provided with a plurality of holes penetrating through the insulation layer and the conductive layer.
