Recent advances in preparation of MOF-derived porous carbon-based materials and their applications in anodes of lithium-ion capacitors
Lithium-ion capacitors represent novel power storage devices amalgamating the features of both lithium-ion batteries and supercapacitors.However,the sluggish dynamics of the lithium-ion capacitor's battery-type negative electrode,compared to the capacitor-type positive electrode,lead to a diminished power density and compromised cycle stability.Notably,porous carbon-based materials derived from metal-organic frameworks(MOFs)have emerged as a focal point in electrochemical energy storage research owing to their expansive specific surface area,porous structure,and exceptional chemical stability.This study analyzes the challenges associated with electrode materials of lithium-ion capacitors and elucidates the energy storage mechanism of lithium-ion capacitors.Subsequently,the influence of carbonization temperature and heat treatment time on the physicochemical properties of MOF-derived porous carbon-based materials is examined.Moreover,diverse products generated through the carbonization process are discussed.Furthermore,the advancements in utilizing MOF-derived porous carbon-based materials in lithium-ion capacitors are reviewed.Finally,the crucial role of composite or doping modifications with other carbon materials in improving the power and energy densities for anode materials of lithium-ion capacitors is emphasized.
