Abstract
High-Performance Carbonyl Electrode Materials for Rechargeable Batteries
Organic carbonyl electrode materials have shown intriguing interests in rechargeable batteries owing to their environmental friendliness, structural designability, high capacity, and wide abundance. However, common organic carbonyl compounds are easily dissolved in aprotic electrolyte, leading to fast capacity decay and undesired shutting problems with cycling. We here proposed a series of strategies to develop high-performance organic carbonyl electrode materials for rechargeable batteries from four aspects, including molecular engineering, electrode design, electrolyte optimization, and separator modification [1–3]. For example, linking small molecules to polymers and introducing high-polarity functional groups (such as –OM, M=Li, Na, K, etc.) to active molecules are effective to solve the dissolution problem. Developing high-concentration liquid electrolyte or solid-state electrolyte can also enhance the cycling stability of organic carbonyl materials. In addition, by means of the cation-selective property of Nafion, we constructed very stable aqueous Zn–calix[4]quinone batteries (up to 1,000 cycles with a capacity retention of 87% at 500 mA g−1) with Nafion as the separator. Moreover, we developed molecular electrostatic potential to effectively predict the lithiation process of organic electrode materials. These strategies would promote further development of organic carbonyl electrode materials and their practical large-scale applications in the future.
