At a cell voltage of 3.0 V, the capacitors made with wet and dry electrodes exhibit a volumetric capacitance of 46.8 and 52.9 F cm −3, respectively. However, as the scanning rate increases, the device made with dry electrodes demonstrates significantly higher capacitances (Figure 6a,b).
The higher volumetric capacitance of supercapacitors with dry electrodes can be attributed to the higher electrode density achieved through the dry process (Table 1), allowing for a more considerable amount of electrode material to contribute to charge storage, resulting in improved energy storage capabilities.
These data show that dry electrode processing enhances the capacitive performances of solid-state supercapacitors, particularly at scanning rates ≥50 mV s −1 (Figure S7C, Supporting Information).
Moreover, the supercapacitor with dry electrodes exhibits a lower equivalent series resistance (ESR) of 6.3 Ω cm 2 compared with 8.4 Ω cm 2 for the cell with wet electrodes (Figure 5d). This lower ESR indicates that dry-processed electrodes improve charge transfer kinetics and reduce internal resistance in the device.
