A binder is commonly used to fabricate electrodes with nanoparticles. The binder makes numerous inter-nanoparticle contacts to maintain the bulky electrode. Herein, we present the preparation of intrinsically conductive solution-processable polymer glues and their excellent performance as binders for electrochemical capacitor electrode. Simply, polyaniline (PANI) was treated with a ternary dopant to have both electrical and adhesive properties. With an optimized composition, the conductive PANI glue (Q-PANI) had a conductivity of 0.9 S cm−1 and 20−25% better adhesive ability than polyvinylidene fluoride insulating binder. Additionally, Q-PANI appeared to have good redox properties in an acidic electrolyte. As a result, use of Q-PANI as a binder has improved the electrode performance of pseudocapacitive and electric double-layer capacitive nanomaterials. |
