Strategies toward High-Loading Lithium–Sulfur Batteries

A high sulfur loading is an essential prerequisite for the practical application of lithium–sulfur batteries. However, it will inevitably exacerbate the shuttling effect and slow down the polysulfide conversion kinetics. To obtain desirable electrochemical performance at a high level of sulfur loading, the adsorption and catalysis dual strategies are widely reported to solve the severe shuttling effect and sluggish reaction kinetics issues. This review mainly summarizes the research on lithium–sulfur batteries with a high sulfur loading (>5 mg cm–2) based on adsorption–catalysis dual promotion strategies. Specifically, we review the principle and technical challenges for lithium–sulfur batteries and recent…
