The simulation results indicate the importance of considering the effect of the Δ𝜙 to understand CVs without supporting electrolyte, as used in many battery systems. This large effect should influence the interpretation of the charge-discharge curve as well as CV. To minimize the influence of Δ𝜙 and improve battery characteristics, the coexistence of a supporting electrolyte may be considered. However, the high concentration of active material in conventional batteries makes it difficult to find a suitable supporting electrolyte of which the solubility is >100 times higher than that of the active material. In addition, a large amount of supporting electrolyte also increases the battery weight. In contrast, in systems with triplet ions and ion acceptors, they are expected to work as supporting electrolytes and as active material supply. These perspectives become more important in further studies for hereafter.
