“…A good binder should provide integrity between the components in the electric network of the composite electrode, allow high adhesion of the active material of the electrode to the current collector, and must be electrochemically and chemically stable. Also, the overall safety and the environmental friendliness of these materials are very important [27][28][29][30]. The commonly used fluorinated thermoplastic binders such as polytetrafluoroethylene (PTFE) and poly(vinylidene fluoride) (PVdF) could be the source of possible pollution [31], and the EDLC electrodes based on these binders should be properly disposed of at the end of the device's lifespan.…”

In the present work, the cellulose-based materials were manufactured and used as components of electrochemical double layer capacitors (EDLCs). The preparation method of cellulose membranes as well as composite electrodes containing cellulose as a binder was presented. These materials were prepared using for the first time ionic liquid/dimethyl sulfoxide (IL/DMSO) mixture solvent. Obtained components displayed a uniform structure, thermal stability, and good electrochemical properties. The electrochemical performances of these materials were studied in 2-electrode EDLC cells by common electrochemical techniques as cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and electrochemical impedance spectroscopy (EIS). The composite electrodes were investigated in three types of electrolytes: aqueous, organic, and ionic liquids. The cellulose membranes were, however, soaked in an aqueous electrolyte and tested as hydrogel polymer electrolytes. All investigated materials show high efficiency in terms of specific capacity. The studied cellulose-based capacitors exhibited specific capacitance values in the range of 20-22 F g −1 , depending on the type of applied electrolyte.

“…Its execution is highly dependent on the specific surface area and conductivity of the electrode materials . There are two widely accepted mechanisms for supercapacitors, that is, electric double‐layer capacitors (EDLCs) and pseudocapacitors . The generally used electrode materials for EDLCs are carbon spheres, activated carbon, carbon nanotubes, reduced graphene, and so on .…”

Novel functionalized polymeric materials incorporated with metal oxide nanoparticles are of paramount importance in the field of supercapacitors. These materials provide the advantage of enhanced specific capacitance coupled with efficient energy storage characteristics. In the present study, a new electrode material has been prepared by modifying the polystyrene maleic anhydride copolymer with 4,4-diaminodiphenylmethane (DDM). Chemically synthesized zinc oxide nanoparticles were incorporated into the polymer matrix at different weight percentages to form polymer nanocomposites (SMA-DDM-zinc oxide (SDZ)). The effect of increasing the weight percentage of nanoparticles on the modified copolymer was studied in details. The samples were characterized using ultravioletvisible, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and thermogravimetric analysis. SDZ was drop casted on the surface of the glassy carbon electrode and the electrochemical properties were studied. Cyclic voltammetry studies were conducted at various scan rates, and the characteristic curves were observed to be pseudorectangular in nature. The specific capacitance values were measured using the chronopotentiometry technique. SDZ 15% nanocomposite shows an enhanced specific capacitance of 313 F g −1 at a current density of 0.05 A g −1 with a power density of 629 W kg −1 . The superior performance of the SDZ nanocomposite electrodes renders it as a promising material for supercapacitor applications.
