چکیده
Supercapacitor electrode slurry is prepared for mass production by mixing activated carbon powder, conductive agent, and binder, which then deposited on a substrate using the doctor-blade method. Polyvinylidene fluoride (PVDF) 1-methyl-2-pyrrolidone (NMP) are used as binder solvent, respectively, to form metal substrate. In this study, ethyl cellulose (EC) evaluated prepare an indium-tin-oxide (ITO) obtaining transparent supercapacitors. Terpineol isopropyl alcohol (IPA) compared suitable solvents EC binder. When terpineol employed agent uniformly around powder. An exhibits slightly lower specific capacitance rate performance than that conventional PVDF NMP. However, securely adheres components, resulting in robust electrode. contrast, IPA high charge transfer resistance at interface of electrode/electrolyte, leading low performance. Thus, ecofriendly can substitute NMP depositing powder ITO substrate, while improving manufactured electrodes.
