A high-voltage and high-safety polyimide gel polymer electrolyte, preparation method and application thereof, and lithium ion battery |
| abstract |
The invention belongs to the field of lithium ion battery gel polymer electrolyte, in particular to a high-voltage and high-safety polyimide gel polymer electrolyte, a preparation method and application thereof, and a lithium ion battery. The preparation method includes: reacting fluorine-containing aromatic diamine and fluorine-containing aromatic dianhydride to obtain a polyamic acid solution; coating the polyamic acid and then subjecting it to high temperature treatment to obtain a polyimide porous film; The membrane is immersed in a high-voltage electrolyte for sufficient swelling to obtain a high-voltage and high-safety polyimide gel polymer electrolyte. The high-voltage and high-safety polyimide polymer electrolyte of the present invention has strong anti-oxidation ability, can make the lithium ion battery have good high-voltage cycle stability, the preparation process is simple and easy, and has strong operability and stability. Processability, has broad application prospects. |
