Abstract

The present disclosure relates to the 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 of the present disclosure includes an insulation layer and a conductive layer. The insulation layer is used to support the conductive layer. The conductive layer is used to support an electrode active material layer and is located on at least one surface of the insulation layer. The insulation layer has a density smaller than that of the conductive layer. The insulation layer has a thickness of Dsatisfying 1 μm≤D≤10 μm. The conductive layer has a thickness of Dsatisfying 200 nm≤D≤1.5 μm. The insulation layer has a tensile strength greater than or equal to 150 MPa.
