In this study, a stepwise cyclic voltammetry approach was proposed to clarify the potential dependence of specific capacitance for reduced graphene oxide and ruthenium oxide electrodes. Based on the relationship between specific capacitance and potential, the working voltage window and energy density of RuO2//RuO2 supercapacitors (SCs) were maximized by modulating the mass ratio. The working voltage window of RuO2//RuO2 with a mass ratio of 2.03 (close to optimum mass ratio m+/m-OPTM=2.04 ) was extended by about 188 % when compared to that calculated at a mass ratio of 0.56. The former was equivalent to a 304 % increase in energy density. In addition, the source of wasted potential window of electrodes on RuO2//RuO2 was investigated in an effort to design and produce better SCs.

With the serious impact of fossil fuels on the environment and the rapid development of the global economy, the development of clean and usable energy storage devices has become one of the most important themes of sustainable development in the world today. Supercapacitors are a new type of green energy storage device, with high power density, long cycle life, wide temperature range, and both economic and environmental advantages. In many industries, they have enormous application prospects. Electrode materials are an important factor affecting the performance of supercapacitors. MnO -based materials are widely investigated for supercapacitors because of their high theoretical capacitance, good chemical stability, low cost, and environmental friendliness. To achieve high specific capacitance and high rate capability, the current best solution is to use MnO and carbon composite materials. Herein, MnO -carbon composite as supercapacitor electrode materials is reviewed including the synthesis method and research status in recent years. Finally, the challenges and future development directions of an MnO -carbon based supercapacitor are summarized.
