Organic redox-active molecules are one of the most promising alternatives to conventional metal oxide-based electrode materials for next-generation secondary batteries due to their advantages in high specific energy and power, low-cost, natural abundance, environmental friendliness, and easy chemical tunability. To date, a lot of organic materials, including conducting polymers, organosulfurs, nitroxides, and carbonyl compounds, have been studied as electrode materials for metal-ion batteries. However, their redox potentials mostly lie on impractical intermediate voltage ranges (＜ 3 V and ＞ 1 V vs. Li/Li+), leaving much room to catch up with the inorganic materials. Furthermore, they are still plagued by high solubility in the liquid electrolytes and by low electric conductivity, which limits their cycle stability, rate performance, and energy density. In this talk, we present novel molecular design strategies to solve such issues for achieving disruptive organic electrode materials.
