Li₂S/metal nanocomposites are synthesized via chemical conversion reactions, and their properties as cathode prelithiation additives have been investigated to offset the initial lithium loss in lithium‐ion batteries. The Li₂S/Co nanocomposite shows good stability, and delivers a high “donor” lithium‐ion specific capacity of 670 mAh g⁻¹ in the cutoff potential range of existing cathode materials in a carbonate‐based electrolyte.

硫化锂/金属纳米复合材料作为高容量阴极预电镀材料

Li ₂ S /金属纳米复合材料是通过化学转化反应合成的，并且已经研究了它们作为阴极预锂化添加剂的性能以抵消锂离子电池中的初始锂损失。Li ₂ S / Co纳米复合材料显示出良好的稳定性，并在碳酸盐基电解质中现有阴极材料的截止电位范围内提供670 mAh g ^-1的高“给体”锂离子比容量。
