ENERGY TECHNOLOGY(SZ:002812)2025-03-12 09:00Group 1: Company Products and Production Capacity - The company's all-solid-state products include lithium sulfide, sulfide solid electrolytes, and sulfide solid electrolyte membranes. The lithium sulfide production line is currently in trial production, with a ton-level solid electrolyte production line established and a thousand-ton pilot production line planned [2][3]. - The company has established a joint venture, Jiangsu Sanhe Battery Material Technology Co., Ltd., with Beijing Weilan New Energy Technology Co., Ltd. and Liyang Tianmu Xian Dao Battery Material Technology Co., Ltd., holding 51% of the shares. It has two production lines capable of mass production [2][3]. Group 2: Market Orders and Collaborations - From 2025 to 2030, Beijing Weilan New Energy is expected to place orders totaling no less than 300 million square meters for semi-solid and all-solid-state battery electrolyte membranes, and no less than 100 tons for all-solid-state battery electrolytes [3]. - The company has signed a procurement framework agreement with Beijing Weilan New Energy, which stipulates that 80% of its material needs will be sourced from Shanghai Enjie and its controlled affiliates [3]. Group 3: Research and Development Focus - The future research direction for sulfide solid electrolytes involves developing products with better air stability, as the current manufacturing process requires isolation from water and oxygen [4]. - The company aims to optimize the particle size and morphology of solid electrolytes to improve conductivity and energy density [8]. Group 4: Cost and Safety Considerations - The cost of semi-solid separators is currently high due to raw material expenses, but market demand for differentiated products is expected to drive down costs as production scales up [5]. - Soft-packaging for solid-state batteries is considered safe, as it has been validated in liquid batteries. The design allows for gas and heat release in case of thermal runaway, reducing explosion risks compared to rigid structures [6]. Group 5: Market Positioning - The company views all-solid-state batteries as currently having higher costs compared to liquid lithium batteries, which offer better cost-performance ratios. All-solid-state batteries are expected to find applications in niche markets such as aerospace and deep-sea exploration [7][8].
