| titleOfInvention | SiO (silicon dioxide)2-PS core-shell structure ceramic coating diaphragm and preparation method and application thereof |
| abstract | The invention relates to the technical field of lithium ion battery diaphragm production, in particular to SiO 2 -PS core-shell structure ceramic diaphragm coating, monodisperse nano SiO prepared by p-St rober method 2 After the particles are modified by in-situ grafting gamma-Methacryloxypropyltrimethoxysilane (MPS), monodisperse nano modified SiO is modified by adopting a mixed solution of polyvinylpyrrolidone ethanol solution and styrene-azobisisobutyronitrile 2 Coating the particles to form a core-shell structure with stable combination effect, and preparing the SiO 2 -PS core-shell structure ceramic diaphragm coating slurry, core-shell SiO 2 The PS composite particles have good dispersibility, can be uniformly dispersed in a coating slurry system without excessive agglomeration, can form a coating which does not block pores of the polyolefin porous diaphragm after being coated on the polyolefin porous diaphragm, and have good combination effect with the polyolefin porous diaphragm, and the whole film has good mechanical properties; the diaphragm has stable film form at high temperature, effectively prevents thermal shrinkage of the diaphragm caused by high temperature, and simultaneously the SiO of the nuclear layer 2 The particles are coated by the glassy polymer, so that the phenomena of shedding of ceramic powder and blockage of a diaphragm pore channel are avoided, the heat resistance and stability of the lithium ion battery diaphragm are improved, and the safety of the lithium ion battery is improved. |
