The present invention belongs to the technical field of battery materials, and provides a lithium-rich lithium ferrite lithium supplementing agent, a synthesis method and a use thereof. In the synthesis method, a solid electrolyte, conductive carbon and elemental sulfur are mixed and subjected to low-temperature heat treatment to form a composite mixture, and then the composite mixture is secondarily mixed with lithium-rich lithium ferrite and subjected to low-temperature heat treatment to form a mixed coating layer on the lithium-rich lithium ferrite, thereby obtaining the lithium-rich lithium ferrite lithium supplementing agent.
