▎ 摘　　要

NOVELTY - Electrolyte composition gel comprises 2-30% unsaturated double bond polymerizable monomer, 0.001-1% initiator, 0.5-5% crosslinking agent, 0.01-5% carbon oxide nano particle, 0.01-5% coupling agent, 50-90% organic solvent and 5-20% lithium salt. USE - Used as electrolyte composition gel. ADVANTAGE - The gel in the electrolyte polymerization is more uniform, improves the power density and cycle performance of the flexible lithium ion battery, and promots further development of flexible lithium ion battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: gel electrolyte prepared from the gel electrolyte composition; A flexible lithium-ion battery adopts the gel electrolyte; and preparing the flexible lithium ion battery, comprising (i) fully mixing the carbon oxide nano particles, initiator and lithium salt in organic solvent, adding to the unsaturated double bond polymerization monomer dissolved with coupling agent and mixing to obtain mixed solution, (ii) carrying out the first polymerization gel the mixed solution to obtain gel electrolyte prepolymer, and (iii) adding cross-linking agent in the electrolyte gel-polymer to mix to obtain precursor of the electrolyte gel and gel electrolyte precursor and injecting into the to-be-injected electric core, carrying out the second polymerization gel under vacuum to form a gel electrolyte. DESCRIPTION OF DRAWING(S) - The drawing shows a preparation process flow chart of a flexible lithium ion battery. (Drawing includes non-English language text).
