This project will create redox-sensitised ion-accessible dense graphene to improve the energy density of supercapacitors (SCs). The energy density of SCs is a bottle neck for long-lasting power supply to vehicles, small devices and mobile electronics. By incorporating a redox coordination framework in shrunk graphene to increase the charge storage capacity and speed up the charge movement and further incorporating ionic liquids in the tailored electrodes, the project will produce SC’s with higher operating voltage and longer cycle life. Such SCs will possess dramatically high energy density, without compromising the power density. This project will improve the efficiency of modern electronics through the development of the next generation of SCs.

该项目将创造氧化还原敏化离子可接近的致密石墨烯，以提高超级电容器（SCs）的能量密度。sc的能量密度是车辆、小型设备和移动电子设备持久供电的瓶颈。通过在收缩的石墨烯中加入氧化还原配位框架来增加电荷存储容量和加速电荷移动，并进一步在定制电极中加入离子液体，该项目将生产出具有更高工作电压和更长的循环寿命的SC。这样的sc将具有非常高的能量密度，而不影响功率密度。该项目将通过开发下一代sc来提高现代电子产品的效率。
