▎ 摘　　要

NOVELTY - Current collector comprises a organic support layer, a conductive layer disposed on at least one surface of the organic support layer, an intermediate coating arranged between the organic support layer and the conductive layer. The intermediate coating layer includes a resin composition, and the resin composition includes a first resin and a second resin. The adhesion force of the first resin to the organic support layer is smaller than the adhesion of the second resin to the organic support layer. The adhesive force of the first resin to the conductive layer is smaller than the adhesive force of the second resin to the conductive layer. USE - The current collector is useful as cathode and/or anode of electrochemical device for electronic device (all claimed). ADVANTAGE - The current collector: can simultaneously consider low quality and good electrical conductivity, current collection and structurally stable and reliable performance, and thus that the electrochemical device can simultaneously consider high gravimetric energy density and good comprehensive electrochemical performance. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the current collector.
