The surface area of the active material plays a very important role here as the number of ions adsorbed or desorbed on the electrode surface depends on it. So, it can be concluded that the higher surface area of the capacitor electrodes implies it has larger capacitance .
Nickel Oxide (NiO) Micro/nanomaterials such as nickel oxide have fascinated a lot of attention by the researcher as electrode material for electrochemical capacitors because of the shortened diffusion paths, fast redox reactions, and a large SSA in the solid phase [229, 230, 231, 232, 233].
These advanced properties provide a vast range of potential for the electrode materials to be utilized in different applications such as in wearable/portable/electronic devices such as all-solid-state supercapacitors, transparent/flexible supercapacitors, and asymmetric hybrid supercapacitors. 1. Introduction
“Green electrode” material for supercapacitors refers to an electrode material used in a supercapacitor that is environmentally friendly and sustainable in its production, use and disposal. Here, “green” signifies a commitment to minimizing the environmental impact in context of energy storage technologies.
