▎ 摘　　要

NOVELTY - A conductive paste comprises a modified graphene, a carbon nanotube, a conductive carbon black, a dispersant and a solvent, where the modified graphene has oxygen-containing functional groups and defects. USE - Conductive paste for use in battery (claimed). ADVANTAGE - The conductive paste has improved comprehensive performance, and charging and discharging performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing conductive paste, which involves pre-treating a graphite-based material to obtain an oxygen-containing functional group and a defect modified grapheme, mixing the modified graphene, carbon nanotubes, conductive carbon black, dispersant and solvent uniformly to obtain the finished product (2) a battery.
