| titleOfInvention | Preparation method of polymer coating film containing P-O bond compound |
| abstract | The invention relates to a preparation method of a polymer coating film containing a P-O bond compound, which is characterized by comprising the following preparation steps: in a reaction kettle, according to the volume ratio (0.1-10): 1, mixing acetone and dimethylformamide to obtain a mixed solution, adding a coating agent accounting for 0.5-2.5 wt% of the mixed solution, 1-5 wt% of polyvinylidene fluoride-hexafluoropropylene and 0.5-2.5 wt% of polymethyl methacrylate, and carrying out ultrasonic oscillation for 10-50 min; stirring the mixture for 8 to 12 hours at the temperature of between 50 and 90 ℃ to prepare viscous liquid. A viscous liquid is applied to the base film which has been subjected to the low-temperature plasma treatment, and a polymer-coated film is obtained by drying. The raw material cost of the invention is lower, the preparation process is simple, the operation is simple and convenient, the time consumption is less, and the prepared coating film is used in a battery system, can improve the discharge performance of the battery, increases the discharge capacity of the battery, improves the cycle performance of the battery, and lays a good foundation for industrialization. |
