【摘要】：正具有高理论能量密度、低成本和环境友好等优点的锂硫(Li-S)电池被视为极具开发潜力的下一代二次电池系统~([1]).近年来,利用碳/硫复合物作为电池正极材料显著提升了Li-S电池的容量和循环寿命.为进一步推动Li-S电池的实用化,研究者们致力于设计高硫负载正极以提升Li-S电池的能量密度~([2]).但现有的高硫负载正极仍面临着两个亟待解决的问题:1)倍率和
[Abstract]:Lithium-sulfur (Li-S) batteries, which have the advantages of high theoretical energy density, low cost and environmental friendliness, are regarded as the next generation secondary battery systems with great potential for development. In recent years, the use of carbon / sulfur complexes as cathode materials has significantly improved the capacity and cycle life of Li-S batteries. To further promote the practicality of Li-S cells, researchers have been working on designing high sulfur loaded positive electrodes to increase the energy density of Li-S cells. However, the existing positive poles of high sulfur load still face two urgent problems: 1) ratio and
