Mass-balancing strategy enhances the cycling stability of rice husk-derived activated carbon-based supercapacitors in KOH electrolyte.

ABSTRACT: Rice husk-derived activated carbon prepared via KOH activation usually has high specific capacitance due to its high oxygen content and high specific surface area, which is regarded as a promising candidate for supercapacitor electrodes. However, the poor cycling stability of supercapacitors based on rice husk-derived activated carbon in KOH electrolyte severely limit its commercial application. In this study, the influence of different positive-to-negative electrode mass ratios on the cycling stability of supercapacitors was systematically investigated using rice husk-derived activated carbon as electrode materials. The results show that increasing the positive-to-negative electrode mass ratios significantly enhances the cycling stability of supercapacitors. In this process, the co
