Electrolytic Study of Pineapple Peel Derived Porous Carbon for All‐Solid‐State Supercapacitors

“…Notably, the performance of EDLC predominantly depends on the choice of electrode material. The electrode material with high SSA and appropriate pores compatible with the electrolyte ions are the demanding factors for EDLC applications [7,8] . For this purpose, carbon materials have emerged as the suitable electrode material owing to its large specific surface area, non‐toxicity, chemical inertness, stability at high temperature, low coefficient of thermal expansion etc.…”

“…Recently, biowaste precursors have been utilized to derive highly porous activated carbon for variety of energy applications. To date various biowaste precursors such as agricultural waste, forest waste, human and animal waste have been utilized to derive activated carbon for EDLC electrode fabrication [8,14–16] …”

“…[2,3] As an electrochemical energy storage device, compared with traditional physical capacitors, the capacitance is much larger, and charge/discharge capacitance is much higher than that of various batteries. [4,5] In general, Carbon materials have excellent performance in terms of electrical conductivity and chemical stability, so they are particularly attractive to SCs with high energy density. [6] Many carbon materials, including graphene, fullerenes, carbon nanotubes, [7] or materials combined with other materials, which have been extensively studied as electrode materials for SCs.…”

“…[6] Many carbon materials, including graphene, fullerenes, carbon nanotubes, [7] or materials combined with other materials, which have been extensively studied as electrode materials for SCs. [5,8] Generally speaking, the electrode materials with high conductivity and fast ion transport are very important and indispensable for high power SCs with stable structure and high efficiency. Carbon materials also have better conductivity than inorganic non-metallic materials.…”
