A composite lithium supplementing material and a preparation method therefor, a positive electrode sheet, a battery, and an electrical apparatus, relating to the technical field of batteries. The composite lithium supplementing material comprises core-shell structure particles, each core-shell structure particle comprising an inner core, and a shell wrapping the outer surface of the inner core. The shell comprises a lithium supplementing agent, and the inner core comprises a reducing agent. The reducing agent comprises at least one of elemental sulfur, elemental boron, lithium sulfide, sodium sulfide and selenium disulfide. By means of forming the lithium supplementing agent and the reducing agent into core-shell structure particles, lithium supplementing efficiency is improved. The lithium supplementing agent is a shell and the reducing agent is a core. Placing the reducing agent in a lithium supplementing agent shell enables the reducing agent to better react with the lithium supplementing agent, and decreases the decomposition potential of the lithium supplementing agent; in addition, the reducing agent can also be combined with anions in the lithium supplementing agent, to generate a stable salt and avoid gas generation. Furthermore, the reducing agent is coated inside the lithium supplementing agent, which can prevent side reactions caused by direct contact between the reducing agent and the electrolyte.
