[0002] With the increasing demand for portable electronic devices (such as smart phones, tablets, etc.), electric vehicles, etc. in modern society, people's expectations for high-performance batteries are also getting higher and higher. Although traditional liquid electrolyte batteries have met market demand to a certain extent, they have some inherent safety hazards. For example, leakage of liquid electrolytes may cause battery short circuits, fires, or even explosions. Solid-state electrolyte batteries can effectively avoid these problems and are safer. In order to realize the commercial production of solid-state electrolyte batteries, it is crucial to develop efficient solid-state electrolyte preparation devices.

The powder burying area and the accommodating component are separately arranged in the sintering container so as to separate the solid electrolyte powder and the blank during the sintering process. The buried powder can replenish the lithium volatilization of the blank and avoid adhesion to the blank. The device reduces the subsequent ceramic sheet surface treatment process and improves the preparation efficiency. It can be widely used in the field of lithium battery technology. However, it is difficult for the device to fully mix the solid electrolyte powder, which is easy to cause deviations in local components, and then in the subsequent links, the quality of electrolyte powder processing is affected.
