数说新能源·2025-12-12 08:01Group 1: Core Viewpoints - The article aims to introduce isostatic pressing equipment, a key device in the production of solid-state batteries, highlighting its importance in addressing production challenges and enhancing material density [2][3][6]. Group 2: Isostatic Pressing Equipment Overview - Isostatic pressing equipment operates based on Pascal's law, allowing uniform pressure application in all directions, which significantly improves material densification compared to traditional unidirectional pressing methods [2]. - The process involves five steps: filling the powder material into a mold, placing it in a high-pressure container filled with a pressure medium, applying pressure, maintaining pressure for a period, and finally releasing pressure to obtain the formed component [2]. - The technology has a history of several decades and is traditionally used in powder metallurgy, ceramics, plastics, and permanent magnets, with new applications emerging in lithium battery production due to the rise of solid-state batteries [2]. Group 3: Relationship with Solid-State Battery Production - The core pain point in solid-state battery mass production is the solid-solid interface contact issue, which can lead to increased internal resistance and safety hazards [2]. - Isostatic pressing equipment plays a crucial role in eliminating gaps and voids at the solid-solid interface, ensuring a stable battery matrix for subsequent packaging and formation processes [2][6]. - The equipment is estimated to account for approximately 13% of the total value of solid-state battery equipment, making it a critical component in the industry [3][6]. Group 4: Key Manufacturers - Notable overseas manufacturers include Quintus Technologies from Sweden, which offers a full range of isostatic pressing equipment, and Hanna from South Korea, which specializes in equipment for sulfide solid-state battery production [6]. - Domestic companies include Liyuanheng, which has partnered with Quintus for joint development, Naconor, and Xiandai Intelligent, all of which are actively involved in the development of isostatic pressing technology [6].
