珠海发布固态电池发展最新行动方案

Core Viewpoint - Zhuhai has issued the "Zhuhai City Action Plan for Promoting the Development of Solid-State Battery Industry (2025-2030)", aiming to seize strategic opportunities in the solid-state battery industry [2] Development Goals - By 2027, Zhuhai plans to establish pilot platforms for the solid-state battery industry, set up five engineering research centers and key laboratories, and attract a number of promising solid-state battery companies. By 2030, the industry chain's key materials, core technologies, and equipment technology levels are expected to improve significantly, forming an initial scale of the solid-state battery industry [2] Key Development Directions - The focus areas include solid-state battery cell manufacturing, production equipment, and materials [3] - In solid-state battery cell manufacturing, the emphasis is on high-end consumer electronics, advancing the industrialization of semi-solid batteries, and the R&D of all-solid batteries. The goal is to enhance energy density, cycle life, and safety while overcoming technical bottlenecks [3] - For solid-state battery production equipment, the focus is on developing low-energy, low-cost, and high-performance equipment, including next-generation battery production devices [4] Solid Electrolyte and Materials - The plan includes developing various technical routes for solid electrolytes, such as oxides, sulfides, and polymers, and improving the mass production technology of ultra-thin solid electrolyte films [5] - In terms of anode and cathode materials, the focus is on lithium-rich manganese-based cathodes, high-nickel ternary cathodes, silicon-carbon anodes, and lithium metal anodes, supporting the development of new electrode materials with higher compatibility [6] Existing Companies and Production Capacity - Zhuhai currently hosts companies like Zhuhai Guanyu, Xinjie Energy, and Haisida. Zhuhai Guanyu has achieved large-scale production of semi-solid batteries, while Xinjie Energy has established a pilot production line for solid-state batteries with an energy density of ≥450Wh/kg, with an annual capacity of 200MWh. Haisida's semi-solid energy storage battery production line commenced operation in March this year, with an annual capacity of 6GWh [6]
