Abstract
A composite current collector includes a base body, a first connecting layer and a first conductive layer, the first connecting layer bonds the first conductive layer to a first surface of the base body; a first passivation layer is formed on one surface of the first conductive layer facing toward the first connecting layer. the first passivation layer may prevent an electrolyte from contacting the first conductive layer and causing the first conductive layer to be corroded and damaged when the electrolyte enters from one surface of the first connecting layer facing away from the first conductive layer, thereby improving the stability of the current collector; an electrode plate and an electrochemical device are provide.
