description The invention discloses a high-voltage electrolyte for a lithium battery, and belongs to the technical field of lithium battery electrolytes. The electrolyte comprises an organic solvent, and the organic solvent is a silicon-based pyrrole ionic liquid. The silicon-based pyrrole ionic liquid is used as the solvent of the lithium metal/ion battery electrolyte, so that the voltage resistance and the lithium metal/graphite compatibility of the electrolyte can be effectively improved. Meanwhile, the solvent in the invention can form a stable interface protection layer on the positive electrode, so that the side reaction of the electrolyte is reduced, and the excellent cycle performance is realized. According to the invention, the lithium salt and the silicon-based pyrrole ionic liquid in the high-voltage electrolyte for the lithium metal/ion battery are specifically combined, and the concentration and the ratio are further optimized; the lithium metal/graphite high-voltage electrolyte added with the electrolyte ha
