Abstract
The present application provides a non-woven fabric separation membrane and a preparation method and a use thereof. The non-woven fabric separation membrane of the present application includes a plurality of fibers, and the fibers are closely connected to each other through a modifier, which significantly improves the tensile strength and the puncture strength of the separation membrane. Meanwhile, molecules of the modifier are grafted on surfaces of the fibers, which improves wettability for an electrolyte solution to the separation membrane, thereby improving the ionic conductivity of the separation membrane and the rate performance of a battery. Ti metal or Zr metal in the modifier molecule can effectively attract an electrolyte anion in the electrolyte solution to improve the ion migration number of the electrolyte solution, reduce battery polarization, and improve the rate performance of the battery.
