Pristine Metal-Organic Frameworks for Sodium-ion Batteries: Past, Present, and Future

Owing to their adjustable redox-active sites, designable structures high porosity, and fully activated organic ligands, pristine metal-organic frameworks (MOFs) have been widely utilized as advanced electrode materials (i.e., both anodes and cathodes) for sodium-ion batteries (SIBs) to satisfied the insertion/extraction larger size and mass of Na+ cations, achieving significant progresses with excellent electrochemical performance in electrochemical energy storage devices. Here, the recent advances on pristine MOFs as anodes and cathodes for SIBs are summarized. A thorough investigation delves into the detailed characteristics, energy storage mechanisms, and electrochemical performance of diverse pristine MOFs for SIBs are also clarified. Furthermore, the outlooks on pristine MOF electrodes in SIBs are also provided.
