摘要:

锂硫电池由于具有能量密度高、 成本低等突出特点, 已经成为下一代高能量密度电化学储能体系的重要发展方向之一. 但锂硫电池的发展仍然存在硫利用率低、 循环寿命短及倍率性能差等亟待解决的关键问题. 单原子催化剂具有高的原子利用率和原子级尺度的结构可调变性等突出特点, 在锂硫电池研究领域受到了广泛的关注. 本文从正极、 负极、 隔膜/中间层3个方面总结了单原子催化剂在锂硫电池中的最新研究进展. 最后, 还对单原子催化剂在锂硫电池中未来的研究发展方向以及需解决的关键科学和技术问题进行了展望, 以期推动单原子催化材料在锂硫电池中的进一步广泛应用.

Abstract:

Lithium-sulfur batteries have become one of the most promising development directions of prospective high-energy-density storage devices due to their outstanding features such as high energy density and low material cost. However, the crucial problems, such as low sulfur utilization rate, short cycle life, and poor rate performance, need to be solved in lithium-sulfur batteries. Single-atom catalysts exhibit high atom utilization and structural adjus-tability at atomic scale. This review summarizes the latest research progress of single-atom catalysts in lithium-sulfur batteries from three aspects: cathode, anode, and separator/interlayer. Finally, we prospect the future development direction and the scientific and technological issues of single-atom catalysts in lithium-sulfur batteries, in order to promote their further widespread applications.

Key words: Lithium sulfur battery, Single-atom catalyst, Lithium polysulfide
