Little attention has been devoted so far to the development of new binders for electrode materials. In this work, an intrinsically conductive solution-processable polymer adhesive was prepared through the combination of polyaniline (PANI) with three organic additives as a ternary dopant for both conducting and gluing properties. With an optimized composition and no heat treatment process or conductive fillers, the conductive adhesive (Q-PANI) had a conductivity of 1.1 S cm−1 and 20–25% better adhesive ability than polyvinylidene fluoride insulating binder. Q-PANI showed good redox properties in an acidic electrolyte. Importantly, Q-PANI itself had a high specific capacitance of 108.7 F g−1. As a result, Q-PANI as a binder was found to significantly enhance the electrode performance of pseudocapacitive nanomaterials (polypyrrole nanospheres and PANI nanofibrils) and electric double-layer capacitive nanomaterials (carbon black). Thus, it is further expected that the combination of conductive and adhesive characteristics will make Q-PANI a very promising conductive paste and coating agent for various applications other than as an electrode binder.
