Abstract: A current collector has a pore-forming functional coating layer, an electrode sheet and a battery. The current collector having a pore-forming functional coating layer comprises an electrically conductive substrate layer and a functional coating layer applied on at least one surface of the substrate layer, wherein the functional coating layer comprises a gas-generating compound which has a decomposition temperature of 250° C. or less and is capable of producing gas. A compound capable of generating gas by decomposition is applied in the functional layer of the current collector. Hence, through holes extending through the coating layer can be produced by decomposing the pore-forming compound at the bottom of the active coating layer to generate gas with no need to change the existing coating process, thereby improving the kinetic performance of battery products. The method is simple, practicable, cost efficient, suitable for popularization, and has high application value.
