Successfully open the all-dry manufacturing process of all-solid-state batteries

Recently, the all-solid-state battery dry manufacturing process (hereinafter referred to as "dry manufacturing process") developed by High Energy Manufacturing has made new breakthroughs and successfully achieved the preparation of multi-material system all-solid-state batteries. This marks that the high energy digital drying process has been widely used in the preparation of all-solid-state batteries of different material systems, and also represents a key step for the industrial application of the high energy digital drying process.

Series 9 ternary and halide materials have very high requirements for the manufacturing process due to their special properties. Among them, the precise atmosphere control of mixing degree and manufacturing process is the key difficulty restricting its industrial application. In view of the difficulties in the dry preparation process, the high energy number of self-developed intelligent mixing and fibrosis equipment to solve these problems, its small external size is only 300*250*230mm, the starting amount of materials is low only 20g, can be flexibly operated in the glove box.

The device can be equipped with a variety of high-energy self-made tool heads, suitable for a variety of battery raw materials, fast 3-5 minutes to achieve high quality mixing and fibrosis, 5 seconds to complete efficient granulation. In addition, the device is equipped with temperature control function and digital display system, which can achieve accurate temperature control.

Breakthrough 2: The dry preparation of halide all-solid electrolyte film was successfully achieved

The continuous preparation of halide electrolyte membrane was successfully achieved by the dry process for the first time, and the dry preparation process and manufacturing process of halide electrolyte membrane were opened up.
