Li 2 S/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 Li 2 S/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.
