Recent advances in coupling carbon-based electrode—Redox electrolyte system

By extending the charge storage from solid to liquid side, carbon materials together with redox electrolytes are recently considered to bring new opportunities for effective energy storage with high energy as well as high output power. Accordingly, intensive efforts have been separately devoted to the development of various carbon materials and redox electrolytes (RE). However, to integrate the carbon electrode and RE to a highly cooperated system with boosted performance, it is critical to focus on the interaction and corresponding enhancement between carbon electrodes and RE species. Hence, we comprehensively highlight the recent strategies for the construction and optimization of the coupled carbon-based electrode-electrolyte system, particularly paying attention to the underlying interaction mechanism and effects on the charge/discharge procedure. Specific concerns are dedicated to the synergistic effects especially on the interfaces.
