▎ 摘  要

NOVELTY - A conductive paste containing carbon material comprises 30 wt.% carbon material, where the carbon material includes conductive carbon black, graphene, carbon nanotubes, and 4 wt.% auxiliary agent. The auxiliary agent comprises dispersant and stabilizer. The dispersant is polyethylene pyrrolidone, polyethylen glycol, polyvinyl alcohol, sodium carboxymethyl cellulose, acrylonitrile multilayer polymer LA132, and/or acryonitrile multi-polymer LA133, polyacrylic acid, and/or polytetrafluoroethylene aqueous solution, and deionized water (remaining amount). USE - The conductive paste containing carbon material is useful in secondary battery e.g. lithium-ion battery and other anode battery of active substance. ADVANTAGE - The conductive paste has excellent dispersibility, conductivity and stability, and improves the output power characteristics of the secondary battery, compact density of the battery pole piece, and radiating performance of battery under the multiplying power discharge and so characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a secondary battery.
