| titleOfInvention | Multilayer structure composite separator and preparation method thereof, as well as secondary battery and electrical equipment |
| abstract | The present application relates to the field of battery diaphragms, and discloses a multi-layer structure composite diaphragm and a preparation method thereof, as well as secondary batteries and electrical equipment. The multi-layer structure composite diaphragm includes a porous polymer base film, nano-oxide particles and dot-like polymers coating; nano oxide particles are completely embedded in the pores of the porous polymer base film and attached to the filamentous structure of the porous polymer base film; dot-like polymer coatings are arranged on both sides of the porous polymer base film. In this application, nano-scale oxide particles are introduced on the porous polymer base film by atomic layer deposition technology, so that all oxide particles with good consistency are embedded in the pore size of the base film, without affecting the original lithium ion channel of the diaphragm. , improve the stability of the separator at high temperature, and also enhance the wettability of the separator to the electrolyte. In addition, the point-like polymer coating on both sides is also more suitable for the existing lithium-ion production scenarios and improves the cycle performance of the battery. |
