Abstract
Supercapacitors (SCs) are considered remarkable energy storage technology because of their prolonged cycling longevity and power density (Pd). However, the constrained energy density (Ed) of SCs presents a notable barrier to their widespread adoption. Therefore, it is crucial to prioritize developing and exploring novel electrode materials to improve their electrochemical performance within SCs usage. The use of metal-organic frameworks (MOFs) in SCs has been subject to thorough investigation by researchers, primarily due to their noteworthy attributes, including but not limited to high porosity, customizable pore structure, and substantial specific surface area (SSA). The main objective of this review is to provide a compressive overview of the latest developments in the realm of pure MOFs and their associated composites, encompassing both MOF composites and MOF derivatives. Particular emphasis is placed on their utilization in the context of SCs applications. Furthermore, we provided individual viewpoints concerning the current challenges and prospective developments of these materials within the framework of SCs application.
