▎ 摘　　要

NOVELTY - The bipolar current collector comprises a porous substrate, a first metal (M), and a second metal (N). One surface of the porous substrate has the first metal, and the other surface has the second metal. The interior of the substrate is present at least one of the first or second metals. The porous substrate comprises carbon material, polymer material, or a third metal, and has a porosity of 20-90%. The carbon material has a single-wall carbon nano-tube film, a multi-wall, porous carbon film, carbon black, acetylene black, fullerene, conductive graphite, or graphene. USE - Bipolar current collector used in an electrochemical device and an electronic device (all claimed) e.g. electric automobile and mobile electronic device such as a lithium-ion battery. ADVANTAGE - The bipolar current collector has a large volume and mass-energy density, long cycle service life, high nominal voltage, low self-discharge rate, small volume, lightweight, and wide application in the consumer electronics field. The output voltage of the electrochemical device is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) an electrochemical device; and (2) an electronic device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the bipolar current collector used in an electrochemical device and an electronic device.
