| 中文摘要: |
| 锂硫电池因其高比容量、高能量密度和低成本等特点已被视为超越锂离子电池的下一代可充电电池。由于反应产物可溶性多硫化物的穿梭效应和循环中硫电极的体积膨胀导致电池的循环寿命较差。为了解决锂硫电池中存在的问题，研究人员开发了多种纳米结构的金属材料。总结了利用钛元素和钛基化合物（包括钛基氧化物、钛基硫化物和钛基氮化物）与硫的反应形成牢固化学键，通过金属基复合材料的结构设计来提升锂硫电池的综合性能。 |

| Lithium-sulfur batteries have been regarded as the next generation rechargeable batteries beyound lithium-ion batteries because of their high specific capacity, high energy density and low cost. The cycle life of the battery is poor due to the shuttle effect of the reaction product soluble polysulfides and the volume expansion of the sulfur electrode during cycling. To solve the problems in lithium-sulfur batteries, researchers have developed a variety of nanostructured metallic materials. This paper summarized the uses of titanium element and titanium-based compounds (including titanium-based oxides, titanium-based sulfides and titanium-based nitrides) to form strong chemical bonds and improve the comprehensive performance of lithium-sulfur batteries through the structural design of metallic matrix composites. |
