Summary: | Disclosed in the present application are a composite positive-electrode lithium-supplementing additive, and a preparation method therefor and the use thereof. The composite positive-electrode lithium-supplementing additive of the present application comprises a core body and a functional packaging layer covering the core body, wherein the core body comprises a positive-electrode lithium-supplementing material, and the functional packaging layer contains an oxygen-consuming agent. The composite positive-electrode lithium-supplementing additive of the present application can effectively remove active oxygen and inhibit active oxygen from initiating a gas production reaction, such that the gas production amount of a battery containing the composite positive-electrode lithium-supplementing additive of the present application during a charging and discharging process can be inhibited, the safety of the battery is effectively improved, and the lithium-supplementing effect and the processing performance are good.
