6 FAQs about [Dry process capacitor preparation]

What is the capacitance of a capacitor made with wet and dry electrodes?

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).

Why do supercapacitors with dry electrodes have higher volumetric capacitance?

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.

Does dry electrode processing enhance the capacitive performance of solid-state supercapacitors?

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).

Do dry-processed electrodes improve charge transfer kinetics in a supercapacitor?

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.

What is the dry method?

The dry method consists of simple three-step processes: 1) preparation of ready-to-press electrode composites powders, 2) formation of free-standing electrode layer, and 3) lamination of electrode.

Are wet electrodes better than dry electrodes for supercapacitors?
