This study utilizes glucose as the precursor and potassium nitrate as an activating agent. It is worth noting that there is currently no literature applying potassium nitrate as an activating agent. The thermal decomposition process of potassium nitrate is employed for the carbonization and activation method, resulting in the high- purity activated carbon with high specific surface area. The production process involves pretreatment, thermal decomposition, and post-treatment. The effects of preparation parameters on the properties of the resulting activated carbon are investigated by varying the ratios of raw material to oxidizing agent, as well as the post-treatment and pretreatment processes.
The final activated carbon samples are chemically characterized using SEM, HRTEM, XRD, UA, PA, and BET techniques. The results indicate that the 5:5 ratio of raw material to oxidizing agent group exhibits the highest specific surface area of 2392.27 m^2/g and favorable pore distribution. Additionally, the optimal pretreatment and post-treatment methods required for fabrication were heating, mixing, and acid washing respectively.
Furthermore, three types of activated carbon samples are fabricated into symmetric electrodes for supercapacitors. The assembled supercapacitors are subjected to electrochemical characterization using techniques such as CV, EIS, and GCD measurements. The results also demonstrate that the supercapacitors prepared from the 5:5 ratio of raw material to oxidizing agent group exhibit the highest specific capacitance, energy density, and cycle life. The specific capacitance exhibits 153.66 F/g, and the energy density is 9.27 Wh/kg, and nearly 90% of the capacitance is retained after 10,000 charge-discharge cycles.
