Summary:A composite lithium replenishment material, a preparation method therefor, and a use thereof. The composite lithium replenishment material comprises a lithium-rich core and an amino acid substance; the lithium-rich core comprises a lithium-containing compound; and the amino acid substance is bonded to the outer surface layer or/and the interior of the lithium-rich core. According to the composite lithium replenishment material, by bonding an amino acid substance to a lithium-rich core, the amino acid substance can react with oxygen species generated by the lithium-rich core and residual alkali, so as to inhibit the reaction between the oxygen species and an electrolyte to achieve the effect of inhibiting gas production, thereby achieving the purpose of improving the electrochemical performance and safety performance of the material.
