| titleOfInvention | A kind of fluorine-containing polyurethane solid-state composite electrolyte and preparation method thereof |
| abstract | The invention discloses a fluorine-containing polyurethane solid composite electrolyte and a preparation method thereof. The electrolyte is composed of a fluorine-containing polyurethane, an inorganic solid electrolyte and a lithium salt. The preparation method includes: S1: preparation of a fluorine-containing dihydroxy monomer; S2: fluorine-containing Preparation of polyurethane; S3: Preparation of fluorine-containing polyurethane solid-state composite electrolyte. The invention adopts polyether polyurethane as solid electrolyte matrix, and its molecular chain contains a large number of ether groups, which can effectively improve the conductivity of lithium ions at room temperature; meanwhile, fluorine-containing polyurethane is prepared by synthesizing a new type of fluorine-containing dihydroxy monomer as chain extender, and the introduction of The fluorine structure effectively improves the electrochemical stability of the polyurethane electrolyte, increases the degree of dissociation of lithium salts to a certain extent, and improves the conductivity of lithium ions; the fluorine-containing structure in the polyurethane effectively improves the mechanical properties and processing properties of the polyurethane solid electrolyte; Polyurethane solid electrolyte is prepared by inorganic composite, which can effectively improve the conductivity of lithium ions and improve the thermal stability and mechanical properties of the electrolyte membrane. |
