▎ 摘　　要

NOVELTY - Solid electrode comprises active material particles, conductive additives, polyion-liquid solid electrolyte and current collector. The conductive additive, polyion liquid solids are uniformly and compactly coated on the surface of the active materials particles. The polyionic liquid solid electrolytes are at least one reactive group of ionic monomers and one of the reactive groups of polymer monomers is obtained by aggregate reaction to obtain a copolymer electrolyte. USE - The solid electrode is used in automobile power battery and military battery. ADVANTAGE - The solid electrode: does not contain ion liquid containing plasticizer; reduces the various problems caused by the plasticizer; is good for reducing the interface impedance between the active particles; improves ion exchange between particles; has lower internal resistance, and excellent multiplying power performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: 1 preparation method of solid electrode; and 2 a solid lithium battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing an internal structure of a solid electrode (Drawing includes non-English language text).
