| Abstract: | AC impedance and voltammetry investigations revealed strong effect of the electrode composition on its machanical and electrical properties and led to its optimization in a CNT‐PVA‐PEG‐SiO2‐KClaq system with good elasticity and excellent electrochemical stability. The uniform distribution of SiO2 and carbon in the polymer fraction was confirmed by SEM imaging. This morphology facilitates retaining water and flexibility of films. An improvement of mass transport in the capacitor electrode as compared to a pure electrolyte was justified based on analysis of the diffusion resistance. The specific capacitance of the electrode and symmetrical capacitor cell is in the mF range and is suitable power system for microelectronic components. |
