Core Viewpoint - The report from Founder Securities highlights the importance of isostatic pressing technology in the production of solid-state batteries, emphasizing its advantages over traditional methods [1][2]. Group 1: Isostatic Pressing Technology - The core principle of isostatic pressing is based on Pascal's principle, where pressure is uniformly distributed in all directions within a high-pressure container [1]. - Isostatic equipment can be categorized into hot isostatic pressing, warm isostatic pressing, and cold isostatic pressing, with warm isostatic pressing being more suitable for solid-state battery applications due to its cost-effectiveness and ability to achieve higher pressure [1][2]. - The introduction of isostatic pressing in solid-state battery production allows for precise control of key parameters such as electrode density, thickness, and porosity, leading to improved ionic conductivity and mechanical strength [2]. Group 2: Industry Landscape - Overseas companies, particularly Quintus Technologies from Sweden and Hana Technology from South Korea, are leading in isostatic pressing technology, while domestic companies are rapidly advancing [3]. - Notable domestic firms that have successfully developed isostatic pressing technology include Sichuan Lieneng (20% owned by Rongqi Technology), Chuanxi Machinery (a subsidiary of AVIC), and Xian Dao Intelligent [3]. - Other domestic companies such as Liyuanheng, Naconoer, Litong Technology, and Xizhuang Co. are also expected to enter the isostatic equipment market, with a focus on companies like Xian Dao Intelligent, Rongqi Technology, and Naconoer [3].
