Abstract
Preparing high-performance electrode materials from metal-organic framework precursors is currently a hot research topic in the field of energy storage materials. Improving the conductivity of such electrode materials and further increasing their specific capacitance are key issues that must be addressed. In this work, we prepared phosphoric acid-functionalized UiO-66 material as a precursor for carbonization, and after carbonization, it was combined with activated carbon to obtain nitrogen-/phosphorus-codoped carbonized UiO-66 composite material (N/P-C-UiO-66@AC). This material exhibits excellent conductivity. In addition, the carbonized product ZrO2 and the nitrogen-/phosphorus-codoped structure evidently improve the pseudocapacitance of the material. Electrochemical test results show that the material has a good electrochemical performance. The specific capacitance of the supercapacitor made from this material at 1.0 A/g is 140 F/g. After 5000 charge-discharge cycles at 10 A/g, its specific capacitance still remains at 88.5%, indicating that the composite material has good cycling stability. The symmetric supercapacitor assembled with this electrode material also has a high energy density of 11.0 W h/kg and a power density of 600 W/kg.
