Sulfide electrolyte membrane and preparation method thereof and solid-state battery
The invention belongs to the technical field of solid-state batteries, and particularly relates to a sulfide electrolyte membrane and a preparation method thereof and a solid-state battery. According to the preparation method of the sulfide electrolyte membrane, a sulfide electrolyte is placed on an inorganic fiber fabric, and is loaded on the surface of the inorganic fiber fabric and/or in pores of the inorganic fiber fabric through tabletting treatment and sintering treatment, and the sulfide electrolyte can be bound in a tiny area by the inorganic fiber fabric, so that a contact interface between sulfide electrolyte particles is changed into a surface contact interface from a point contact interface so as to improve the contact area; the sulfide electrolyte and the inorganic fiber fabric jointly form a uniform and compact sulfide electrolyte membrane with certain flexibility through sintering treatment, so that the problems that the sulfide electrolyte is prone to pulverization and difficult to transfer are solved.
本发明属于固态电池技术领域，具体涉及一种硫化物电解质膜及其制备方法、固态电池。本发明硫化物电解质膜的制备方法通过将硫化物电解质置于无机纤维织物上，经压片处理和烧结处理使硫化物电解质负载于无机纤维织物的表面和/或无机纤维织物的孔隙中，无机纤维织物可将硫化物电解质束缚在微小区域，使硫化物电解质颗粒之间的接触界面由点接触界面变为面接触界面，提高了接触面积；同时，烧结处理使硫化物电解质与无机纤维织物共同形成均匀致密且具有一定柔性的硫化物电解质膜，解决了硫化物电解质容易粉化、难转移的问题。
