제목 Achieving high-energy density and superior cyclic stability in pseudocapacitor via cross-linked high durable polymer binder
초록 Many innovative technologies have been developed to improve the properties of polymers. Among them, the most effective and easy way to do so is cross-linking. Herein, we have designed a breakthrough complex process (cross-linking and composite technique) that brilliantly builds the physical properties of the polymer in simple one step. The quaternization of cross-linkable organic/inorganic hybrid polymer was used for backbone poly(4-vinyl-pyridine), poly(vinyl imidazole) with a unique functional group-containing ethoxy silane. We checked the chemical structure of polymer composite via FT-IR and 1H-NMR. Also, it has been confirmed that the thermal stability and mechanical properties of the polymer have improved. Hybrid polymer for electrode binder of pseudocapacitors exhibit higher capacitance value and energy density with improvement of cyclic stability. This study reveals cross-linked networks in the hybrid polymer are long cycle-life features for electrochemical redox capacitors.
