[0002] As a national strategic emerging industry to cope with environmental pollution and energy crisis, electrochemical energy storage presents a good situation of vigorous development, and will have greater role in the future. Battery production is a complex process involving multiple steps, mainly including raw material preparation, battery component manufacturing, battery assembly and testing, etc. In the whole battery production process, it is crucial to strictly control the quality and safety of each link to ensure the production of high-quality battery products meeting the standards. With the development of technology, the battery production process is also continuously optimized and improved to improve production efficiency and product quality. In the battery production process, pneumatic conveying of battery raw materials is particularly important. During pneumatic conveying, the inner wall of the material pipe is easily contaminated with materials, and compressed air needs to be delivered by a nozzle for cleaning.

[0003] Many existing filter nozzles are made of copper or zinc material. During pneumatic conveying, materials are easily impacted on the filter nozzle, causing wear of the filter nozzle. After wear, copper material is carried into the interior of the battery raw material, affecting the production quality of the battery. Therefore, we propose a stainless steel filter nozzle. SUMMARY
