Abstract
A material composition to prepare a polymer electrolyte precursor composition capable to form a solid polymer electrolyte, which has: A) a comb-branched polymer with pendant functional groups; B)surface-modified silica particles; and C) a polymerizable solvent or a crosslinker; wherein the silica particles are capable to be dispersed in the polymerizable solvent or a non-polymerizable volatile organic solvent and form a colloidal silica dispersion can be made. The material composition can be used in preparation of a solid polymer electrolyte in a lithium ion battery to improve performance, a polymer electrolyte precursor composition, a preparation method of a solid polymer electrolyte, a method to prepare a lithium ion battery, a solid polymer electrolyte, an electrochemical device and a device.
