Application of Inorganic Quantum Dots in Advanced Lithium–Sulfur Batteries

Abstract: Lithium–sulfur (Li‐S) batteries have emerged as one of the most attractive alternatives for post‐lithium‐ion battery energy storage systems, owing to their ultrahigh theoretical energy density. However, the large‐scale application of Li–S batteries remains enormously problematic because of the poor cycling life and safety problems, induced by the low conductivity, severe shuttling effect, poor reaction kinetics, and lithium dendrite formation. In recent studies, catalytic techniques are reported to promote the commercial application of Li–S batteries. Compared with the conventional catalytic sites on host materials, quantum dots (QDs) with ultrafine particle size (<10 nm) can provide large accessible surface area and strong polarity to restrict the shuttling effect, excellent catalytic effect to enhance the kinetics of redox reactions, as well as abundant lithiophilic nucleation sites to regulate Li deposition. In this review, the intrinsic hurdles of S conversion and Li stripping/plating reactions are first summarized. More importantly, a comprehensive overview is provided of inorganic QDs, in improving the efficiency and stability of Li–S batteries, with the strategies including composition optimization, defect and morphological engineering, design of heterostructures, and so forth. Finally, the prospects and challenges of QDs in Li–S batteries are discussed.
