Abstract
Metal-organic framework (MOF) materials are a new kind of porous crystalline materials assembled by metal ions and organic ligands. Due to their high specific surface area, controllable structure and adjustable pore size, metal–organic framework materials can be used as precursors or templates for composite materials derived from metal oxides and electrochemical energy storage applications. Energy storage devices mainly include supercapacitors and batteries, and electrode materials are their key components, which greatly affect device performance in application. The metal oxides and their composites prepared from the metal–organic framework are excellent electrode materials with high reversible capacity, excellent rate and cycling properties. In this paper, the applications of MOF-derived metal oxides and their composites in supercapacitors (SCs), lithium-ion batteries (LIBs), sodium-ion batteries (SIBs) and zinc batteries (ZIBs) are reviewed. Finally, the future development opportunities and challenges of MOF-derived metal oxides and their composites are discussed.
