中孚新能源发布“萨拉弗凝胶聚合物电解质膜”，零产线改造破解“史上最严电池安全令”难题

Core Viewpoint - The article emphasizes the significant advancements in battery safety standards driven by new regulations, highlighting the introduction of the "Salaf" gel polymer electrolyte membrane by Cangzhou Zhongfu New Energy Materials Co., Ltd. as a breakthrough solution for achieving safety and performance in battery technology [1][2][14]. Summary by Sections New Regulations and Industry Impact - The new regulations set by the Ministry of Industry and Information Technology (MIIT) will be implemented in 14 months, mandating that batteries must not catch fire or explode, introducing stringent testing standards [1]. - The industry is facing a technological revolution due to these regulations, necessitating improvements in safety and compatibility [2]. Salaf Technology Overview - The "Salaf" technology utilizes a gel polymer electrolyte membrane that allows for a quasi-solid-state battery upgrade without the need for production line modifications, maintaining cost parity with traditional liquid batteries [3][12]. - The technology addresses the flammability issues of traditional liquid electrolytes while avoiding the high costs associated with fully solid-state batteries [3]. Core Safety Advantages - High-Temperature Stability: The Salaf membrane features a molecular matrix that actively prevents thermal runaway by forming a thermal barrier and releasing flame-retardant groups at temperatures above 150°C [4]. - Impact Resistance: The multi-layer structure of Salaf provides significant resistance to mechanical damage, with a break elongation rate of ≥300%, effectively reducing the risk of short circuits during puncture tests [5]. - Chemical Stability: The gelification process enhances the chemical stability of the electrolyte, with a chemical window greater than 5V, significantly reducing the risk of electrolyte decomposition [7]. Performance Validation - Salaf has been validated by multiple leading battery manufacturers, demonstrating compliance with new regulatory requirements and maintaining over 80% capacity retention after 1000 charge-discharge cycles [9]. - In lithium iron phosphate systems, Salaf exhibited no thermal runaway during puncture tests and maintained a capacity retention of 92% after 1400 cycles [9]. Market Expansion and Future Prospects - Salaf is currently receiving sample and small-batch trial orders from various battery manufacturers, indicating initial trust in its performance advantages [11]. - The company plans to scale production, with a target capacity of 1.5 billion square meters by 2026, sufficient to meet approximately 70-90 GWh of battery demand [9][12]. - Salaf is also exploring applications beyond consumer electronics and automotive batteries, including energy storage and eVTOL markets [13]. Conclusion - The introduction of Salaf represents a sustainable path for balancing safety, cost, and performance in the battery industry, potentially reshaping the competitive landscape as the 2026 deadline approaches [14].
