摘要
本文系统综述了室温钠硫电池碳基宿主材料的设计及其近期的研究进展。首先阐述了室温钠硫电池的电化学工作原理,介绍了室温钠硫电池面临的关键问题。归纳了近期提出的一些针对硫正极设计的常用方法,比如纳米结构约束、非金属杂原子掺杂、金属单原子掺杂、异质结构在吸附-催化协同作用中的应用。这些设计从不同角度改善多硫化物的穿梭和钠与硫之间缓慢的氧化还原动力学。最后对室温钠硫电池硫正极碳基宿主的现实应用开发研究进行了展望。
This paper presents a systematic review of studies in the design of carbon-based host materials for room-temperature sodium-sulfur batteries.Firstly,it described the electrochemical working principle of room temperature sodium-sulfur cells,introduced the key issues facing by room sodium-sulfur cells,and demonstrated some of the common tools recently proposed for the design and improvement of sulfur cathode levels,such as nanostructural constraints,non-metallic heteroatom doping,metallic mono-atom doping,and heterostructures in adsorption-catalysis synergies.These designs addressed the critical issues of polysulfide shuttling effects and slow electrode kinetics of sodium oxidation and sulfur reduction from different perspectives.Finally,certain research perspectives were presented for the practical application needs of the sulfur ortho-grade carbon-based hosts for room-temperature sodium-sulfur batteries.
