Polyzwitterionic Ion gel-based Electrochromic Supercapacitors with Low Self-discharging Performance |
| 초록 |
Monolithic electrochromic supercapacitors (ECSs) have attracted ever-growing interest in recent electrochemical electronics due to their simplicity and unique function of visual indication of stored energy level. One crucial challenge for practical use is the improvement of shelf-life. Herein, zwitterionic (ZI) ionogels are proposed as effective electrolytes to reduce self-discharging decay of ECSs. All-in-one ZI electrochromic (EC) gel does not affect the EC characteristics of chromophores. In addition, excellent capacitive properties in areal capacitance and coulombic efficiency are presented owing to the alignment of ZI units under electric field and the formation of ion migration channels where rapid ion transport is allowed. Furthermore, the shelf-life of the ZI gel-based ECS is significantly improved by adjusting the interaction between polymeric gelators and ion species. We expect that the ZI gel-based ECS will be a key platform for future smart energy storage devices. |
