Preparation method of solid electrolyte membrane coated on pole piece and application of solid electrolyte membrane in lithium ion battery

The invention discloses a preparation method of a solid electrolyte membrane coated on a pole piece and application of the solid electrolyte membrane in a lithium ion battery. The solid electrolyte membrane comprises a fast ion conductor, a polymer matrix and a lithium salt. It is worthy of notice that the solid electrolyte membrane is prepared into a rheological body state through simple stirring under the conditions of no inert gas protection/inert gas protection and no humidity control, the surface of the prepared pole piece is coated with the solid electrolyte membrane to form the solid electrolyte layer, the experiment process is simple, and the air stability is high. The prepared solid electrolyte membrane shows excellent electrochemical performance after being assembled into a chargeable and dischargeable battery, and the cycling stability and the safety performance of the lithium ion battery are effectively improved. 本发明公开了一种涂敷于极片上的固态电解质膜的制备方法及其在锂离子电池中的应用。所述固态电解质膜包括快离子导体、聚合物基体和锂盐。值得注意的是，所述固态电解质膜在无惰性气体
