“…This behavior indicates good ion transport across the interconnected porous networks of BSPC, owing to the increased accessibility of the electrolyte ions to the inner active area of electrodes. The 3D porous structure of BSPC can play a crucial role in increasing capacitive performance at high charge-discharge rates and enabling the circulation of electrolyte ions across the electrode surface [35]. Thus, the BSPC retains a similar CV shape even at scan rates from 10 mV s −1 to 100 mV s −1 , demonstrating its high rate-retention capability.…”

Electrochemical energy storage (EES) systems are attracting research attention as an alternative to fossil fuels. Advances in the design and composition of energy storage materials are particularly significant. Biomass waste-derived porous carbons are particularly suitable for use in EES systems as they are capable of tuning pore networks from hierarchical porous structures with high specific surface areas. These materials are also more sustainable and environmentally friendly and less toxic and corrosive than other energy storage materials. In this study, we report the creation of a three-dimensional hierarchical porous carbon material derived from betelnut shells. The synthesized three-dimensional (3D) hierarchical porous carbon electrode showed a specific capacitance of 290 F g−1 using 1 M KOH as an electrolyte at a current density of 1 A g−1 in three-electrode systems. Moreover, it offered a high charge/discharge stability of 94% over 5000 charge–discharge cycles at a current density of 5 A g−1. Two-electrode symmetric systems show a specific capacitance of 148 F g−1, good cyclic stability of 90. 8% for 5000 charge-discharge cycles, and high energy density of 41 Wh Kg−1 at the power density of 483 W Kg−1 in aqueous electrolyte.

“…Important for KOH-activated carbon is that it majorly results in an increased specific surface area and pore volume/ micropore volume, uniform pore size distribution, and controllable surface functional groups which is mostly dependent on the activation parameters and carbon sources used [200].

This review covers research on the use of potassium hydroxide (KOH) to produce and modify activated carbon. The methods employed for activation by considering the activation process, carbonization, temperature, activation time, and KOH ratio to material are described and how the surface area, surface morphology, and functional groups are affected by the KOH ratio. Characterization techniques and preparation conditions are summarized. The activated carbon pore structure mainly depends on the burn‐off size and the time for activation is linked to the overall activation reaction rate. The increase in surface area and pore size depends on the ratio of KOH, showing that KOH affects the surface chemistry of the activated carbon. The sorbent‐sorbate interactions are strongly influenced by different parameters, which were also calculated in this review and used to evaluate such interactions.
