Beschreibung
Zusammenfassung:	A lithium-replenishing additive is provided in the present disclosure. The lithium-replenishing additive includes a lithium-rich-material core and a shell layer disposed at the lithium-rich-material core. The lithium-rich-material core is made of a lithium-rich material with an average chemical formula of aNixMyOz·bLi2O, where 0.95≤x≤1, 0.01≤y≤0.05,1≤z≤1.15, 0.8≤a≤1.1, 0.8≤b≤1.1, and the M includes one or more of copper (Cu), cobalt (Co), aluminum (Al), titanium (Ti), vanadium (V), zirconium (Zr), or iron (Fe). The shell layer includes a polymer layer. The lithium-replenishing additive not only can effectively replenish a lithium secondary battery with lithium to improve a first efficiency of a battery, but also can have good stability to be not easy to react in air, which is beneficial to production, storage, and transportation of the lithium-replenishing additive. A preparing method of a lithium-replenishing additive is further provided in the present disclosure.
