Recent Progress on Functional Metal–Organic Frameworks for Supercapacitive Energy Storage Systems

Abstract

As porous coordination organic polymers, both metal–organic frameworks (MOFs) and their derived materials and MOF‐based composites offer unique organic or inorganic chemistries that display superior features of high specific surface area, accessible active sites, robust structural and chemical diversity, tailorable pore size, exceptional porosity, and pre‐ and postsynthesis structural tunability. Therefore, MOF‐based materials are attractive for energy storage applications, specifically for supercapacitor devices. This review presents recent progress in designing and utilizing pristine MOFs, MOF‐derived nanomaterials, and MOF‐based composite materials for supercapacitors. Most importantly, herein, recent highlights and classifications of electrolytes and their vital role in the structure–property correlation between the structures of MOF‐based materials and suitable electrolyte choices for ideal supercapacitor devices are discussed. Finally, together with a discussion of the progress and outcomes of MOF electrodes, the obstacles and prospects for future MOF‐related research and applications are discussed. To help this intriguing topic continue to advance, this review offers useful insights into the logical design of MOF‐based electrode materials.

Life Cycle Assessment of Energy Storage Technologies for New Power Systems under Dual‐Carbon Target: A Review

“…Currently, the global energy industry's carbon emissions account for more than 80% of the total, while the power industry's carbon emissions in the energy industry account for more than 40%. [ 3 ] The statistics of Multi‐resolution Emission Inventory for China [ 4 ] indicate the global CO 2 emissions in four different fields of power, industry, ground transport, and residential, domestic aviation, and international aviation in the past 4 years from 2019 to 2022. This is displayed in Figure 1 .…”
