Application of Inorganic Quantum Dots in Advanced Lithium–Sulfur Batteries

Advanced Science, Год журнала: 2023, Номер 10(19)

Опубликована: Апрель 23, 2023

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

Abstract The slow redox kinetics and severe shuttle effect caused by the diffusion of lithium polysulfides (LiPSs) severely hinder practical application lithium–sulfur (Li–S) batteries. construction utilization catalytic electrode materials are promising strategies to effectively suppress accelerate sulfur species. This work reports a simple hydrothermal‐ultrasonic combined method construct conductive titanium carbide quantum dots (Ti 3 C 2 QDs) supported on carbon nanotubes (CNTs) QDs@CNTs composites) as efficient electrocatalysts for Li–S Based analysis dynamic evolutions Ti QDs catalysts species, 3+ 4+ species can be identified active that Li S nucleation dissociation. Due abundant sites from QDs, catalyze conversion LiPSs. Moreover, CNTs matrix significantly enhance charge transport, allowing rapid + /electron transfer. As result, QDs@CNTs/S exhibits high initial capacity, good rate capability, improved long‐term cyclability. provides strategy introduce into cathode battery achieve better electrochemical performance.
