| titleOfInvention | A kind of separator of water-based battery and preparation method thereof |
| abstract | The invention discloses a separator for an aqueous battery and a preparation method thereof. The separator is a PVDF-based porous film with a microporous structure. In addition, the separator can also be a PVDF-based composite separator obtained by using a PVDF porous membrane as a base layer to modify one side or both sides. The preparation steps mainly include the steps of film-forming solution preparation, solution phase inversion film-forming, surface functionalization treatment, preparation of coating layer slurry, coating and drying. The invention solves the problems of poor wettability and mechanical properties of the separator in the water-based battery, low temperature resistance and the like. The PVDF-based porous separator used in aqueous zinc batteries can reduce the polarization voltage of the battery and suppress zinc dendrites. The preparation process of the invention is simple and feasible, and the cost is low, which is favorable for large-scale popularization and application. |
