Framework materials for supercapacitors

Framework materials for supercapacitors: Supercapacitors are perfect energy storage devices with superior cycling life, remarkable power/energy density, fast charge–discharge rates, and environmental friendliness. Frameworks materials, including metal organic frameworks (MOFs), Prussian blue/Prussian blue analogs (PB/PBAs), and covalent organic frameworks (COFs), are outstanding candidates in supercapacitors. In this review, we mainly report typical research progress on framework materials, their derivatives, and composites in a supercapacitor.
