Abstract
Developing economic and efficient energy storage devices is crucial in the shift towards sustainable energy solutions. Our present work explores the potential of utilizing decayed tomato as a sustainable precursor to produce activated porous carbon electrodes in the construction of supercapacitors. By utilizing the carbonization-activation process and carefully adjusting the preparation parameters, we have achieved an excellent specific surface area (SSA) of 880.33 m2 g-1. This tomato waste char (TWC) predominantly consists of nanopores with a total pore volume of 0.5713 cm3 g-1 and an average pore diameter of about 2.5958 nm. These parameters play a vital role in determining the supercapacitor behavior of the sample. A specific capacitance of 110 F g-1 at 1 mA has been recorded. Furthermore, an energy density of 14.97 Wh kg-1 at 1 mA is observed. This work has reported a high-value power density of about 4163.4 W kg-1 using a symmetric type supercapacitor.
