Recent Advances in Transition-Metal-Based Catalytic Material for Room-Temperature Sodium-Sulfur Batteries

摘要

Room-temperature sodium-sulfur (RT Na-S) batteries have emerged as apromising candidate for next-generation scalable energy storage systems, dueto their high theoretical energy density, low cost, and natural abundance.However, the practical applications of these batteries are hindered by thenotorious shuttle effect of soluble sodium polysulfides (NaPSs) and sluggishreaction kinetics, which result in fast performance loss. To address this issue,recent studies have reported impressive achievements of transition metalnanoparticles/single atoms/cluster/compounds (TM)-based host materialswith strong adsorption and catalyzation to NaPSs. These materials cansignificantly improve the electrochemical performance of RT Na-S batteries.In this review, the recent progress on TM-based host materials for RT Na-Sbatteries, including iron (Fe)-, cobalt (Co)-, nickel (Ni)-, molybdenum (Mo)-,titanium (Ti)-, vanadium (V)-, manganese (Mn)-, and other TM-basedmaterials are summarized. The design, fabrication, and properties of thesehost materials are comprehensively summarized and systematically analyzedthe underlying chemical inhibition and electrocatalysis mechanism betweenNaPSs and TM-based catalytic materials. At last, the challenges and prospectsfor designing efficient TM-based catalytic materials for high-performance RTNa-S batteries are discussed.
