COMPOSITION OF NANOPARTICLE BASED ON ORGANIC-INORGANIC HYBRID AND NANOCOMPOSITE POLYMER ELECTROLYTE FOR LITHIUM POLYMER RECHARGEABLE BATTERIES

摘要

Provided are a nanoparticle of organic/inorganic hybrid type in which surface of inorganic nanoparticle is substituted with functional organic materials, and a nanocomposite polyelectrolyte applying the same. The nanocomposite polyelectrolyte comprises nanoparticles, wherein surfaces of the inorganic nanoparticles are substituted with organic monomers excellently compatible to liquid electrolyte and organic monomers comprising lithium ion. Diameters of the inorganic nanoparticles are 1-10000 nm. The surface of the inorganic nanoparticles are admixed with 1, 2 or more of silica(SiO2) having hydrophilic hydroxyl group(-OH), aluminum oxide(Al2O3), titanium oxide(TiO2), or zeolite. The composition of nanocomposite polyelectrolyte comprises (i) 1-90 wt% of the nanoparticles of organic/inorganic hybrid type; (ii) 1-50 wt% of crosslinking monomer; (iii) 0-50 wt% of comonomer; (iv) 1-95 wt% of organic solvent; and (v) 0.1-5 wt% of initiator.
