AI Technical Summary
Traditional lithium-ion ceramic electrolyte tube manufacturing processes are technically challenging, have high equipment costs, and low production efficiency, making it difficult to achieve mass production of large-size ceramic tubes, and the resulting ceramic tubes have poor performance.
Inorganic solder is used to weld straight or bent lithium-ion ceramic electrolyte tubes that are easy to form and sinter to ceramic end caps, forming a lithium-ion ceramic electrolyte tube with one end sealed. Lithium-ion ceramic electrolyte materials such as LLZO, LATP, and LLTO are used, and welding is performed using a mixture of inorganic solders such as Li2CO3, Li2O, LiOH and Al2O3. The welding temperature and time are controlled at 900-1200℃ and 10-120min.
It has achieved high-quality and high-efficiency production of large-size lithium-ion ceramic electrolyte tubes. The products have good airtightness and are stable to lithium metal, MBR molten salt and lithium-saturated MBR molten salt. The welding technology is simple, the production efficiency is high and the equipment cost is low.
