▎ 摘　　要

NOVELTY - A heterogeneous connected material with high-conductivity functional groups at zinc grain boundary, comprises high-conductive carbon material which forms uniformly wound and staggered strip-shaped conductive network, and zinc particles whose grain boundary aggregates are connected to form a complete uniform bridge structure. USE - Heterogeneous connected material with high-conductivity functional groups at zinc grain boundary. ADVANTAGE - The high-conductivity functional group heterogeneous connection material is prepared in batches, by controlled and simple process, and has high stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the heterogeneous connected material with high-conductivity functional groups at zinc grain boundary, which involves (s1) transferring the high-conductive carbon material and process control agent into low-oxygen environment, adding anhydrous solvent, mixing with powdered zinc material, (s2) transferring the mixed into a high-speed ball mill, performing variable-speed ball-milling treatment to obtain a carbon material mixed with powdered zinc material, and (s3) placing the carbon material mixed with powdered zinc material in a mold, placing the mold in a plasma machine, rapidly heating, and heating at high speed, and curing using axial force and pulse current.
