wsdl(SH:600995) 中关村储能产业技术联盟·2025-06-03 11:46Core Viewpoint - The article emphasizes the importance of safety in the application of lithium-ion battery energy storage systems, highlighting a project that has developed a comprehensive safety technology system for the entire lifecycle of these systems [2][3]. Group 1: Project Overview - The project titled "Safety Technology for the Full Lifecycle Application of Lithium-Ion Battery Energy Storage Systems" aims to address challenges such as disaster mechanisms, fault diagnosis, accident early warning, and fire control in lithium-ion battery storage [3]. - The project is led by Southern Power Grid Energy Storage Co., in collaboration with institutions like the University of Science and Technology of China and Beijing Institute of Technology [2]. Group 2: Fire Safety Testing Platform - A major outcome of the project is the establishment of a full-scale battery system fire simulation testing platform, which is the first of its kind in China, designed to conduct various fire tests for energy storage technologies [4]. - Since its launch in July 2023, the platform has conducted over 800 fire tests across different battery types, including lithium, sodium, and solid-state batteries [4]. Group 3: Early Fire Detection and Monitoring - The project has developed a safety monitoring platform that can detect early signs of faults, thermal runaway, and explosions, providing a crucial 15-minute window for response [5][6]. - The platform utilizes data from over 4.7 million measurement points and employs advanced algorithms for real-time analysis, achieving an accuracy rate of 97.6% [5]. Group 4: Innovative Fire Suppression Technology - The project has introduced the world's first fluorine-free fire extinguishing materials in energy storage systems, significantly improving fire suppression efficiency [7][8]. - The new liquid nitrogen-based fire suppression system can extinguish initial battery fires within 5 seconds, doubling the efficiency of previous methods [7]. Group 5: Overall Impact and Future Prospects - The project has resulted in a comprehensive set of safety control technologies for energy storage systems, with a demonstration application scale exceeding 1,000 MWh, equivalent to the construction of five large-scale storage stations [8]. - The initiative has not only led to key technological innovations but also fostered a new generation of safety technology talent in the energy storage sector [8].
