Abstract
A novel water‐soluble cationic polyacrylamide/polyaniline (CPNi) conductive and mechanical robust binder is designed and fabricated. PANi units possessed by CPNi can provide electrical conductivity for this system, and the crosslinking network between polyacrylamide and polyaniline can form via chemical bonds and its intermolecular hydrogen bonds. The effect of PANi is investigated via the electrochemical behaviors and mechanical properties. The CPNi6 sample could balance electrochemical and mechanical properties. It exhibits a superior discharge capacity of 120 mAh g−1 at 200th cycle under the current density of 1C and an excellent discharge capacity of 118 mAh g−1 at 5C‐rate.
