▎ 摘　　要

NOVELTY - A conductive composition comprises a polymeric material and a conductive additive comprising a carbon nanomaterial, a polymeric dispersant and an anionic dispersant. USE - Conductive composition used in cathode slurry for preparing cathode (all claimed) for secondary battery for use in electronic device. ADVANTAGE - The conductive composition used in cathode slurry having enhanced stability, and does not lower the battery performance such as cyclability and capacity, and produces battery having high cycle stability, and which is economical and ease of handling. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a cathode slurry for secondary battery, which comprises a cathode active material, the conductive composition and a conductive agent; (2) preparation of the conductive composition; and (3) preparation of cathode for a secondary battery, which comprises the conductive composition.
