A kind of preparation method of fluorine-containing meta-aramid-based polymer electrolyte modified by montmorillonite and polyethyleneimine |
| abstract |
The invention discloses a preparation method of a fluorine-containing meta-aramid-based polymer electrolyte modified by montmorillonite and polyethyleneimine. The preparation method comprises the following steps: 1) meta-aramid emulsion, polyvinylidene fluoride- Hexafluoropropylene and montmorillonite were dissolved in dimethylacetamide according to a certain proportion to prepare a spinning solution; 2) Fluorine-containing meta-aramid film was prepared by electrospinning; 3) Dip coating solution was prepared: prepare Tris HCl buffer solution, then add dopamine hydrochloride and polyethyleneimine in a certain proportion; 4) put the polymer film into the dip coating solution; 5) carry out hot pressing under certain conditions; 6) drip 1.0M on the diaphragm of lithium hexafluorophosphate electrolyte dissolved in a mixed solvent of ethylene carbonate (EC), diethyl carbonate (DEC) and ethyl methyl carbonate (EMC) (volume ratio 1:1:1). The polymer electrolyte prepared by this method can effectively improve the electrochemical performance of lithium-ion batteries. |
