Title:
CONDUCTIVE COMPOSITION FOR SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/254155
Kind Code:
A1
Abstract:
A conductive composition for a secondary battery, a slurry comprising the same, an electrode comprising the same and a method of preparing the conductive composition are provided. The conductive composition comprises a polymeric material, a carbon nanomaterial and an anionic stabilizing agent. The polymeric material comprises a copolymer comprising a structural unit derived from an acid group-containing monomer and a structural unit derived from a polar group-containing monomer. The conductive composition exhibits an improved stability and dispersibility in water. In addition, battery cells comprising a cathode prepared using the conductive composition disclosed herein exhibit impressive electrochemical performances.
