Energy Storage Safety Standards Are Evolving: What New Challenges Do Passive Fire Protection Materials Face?
【Summary】 With the rapid expansion of the global battery energy storage system (BESS) market, safety has become one of the most critical concerns for energy storage manufacturers, integrators, and operators.
Global Energy Storage Growth Raises New Safety Challenges
With the rapid expansion of the global battery energy storage system (BESS) market, safety has become one of the most critical concerns for energy storage manufacturers, integrators, and operators.
As battery energy density continues to increase, thermal runaway events inside lithium-ion battery systems have attracted increasing attention. Once a single battery cell experiences thermal runaway, extreme heat, flame, and gas release may trigger thermal propagation, potentially affecting adjacent cells, battery modules, and even the entire energy storage container.
To address these risks, safety standards worldwide are continuously evolving, creating higher requirements for passive fire protection materials used in energy storage systems.
Global Energy Storage Safety Standards Are Becoming More Comprehensive
China has accelerated the development of its energy storage safety standard system in recent years, covering battery cells, battery systems, and energy storage power station design.
Key standards include:
• GB 44240-2024 Safety Requirements for Lithium Batteries and Battery Packs Used in Electrical Energy Storage Systems
• GB/T 36276-2023 Lithium-ion Batteries for Electrical Energy Storage
• GB/T 51048-2025 Design Standard for Electrochemical Energy Storage Stations
• T/CFPA 055-2026 Fire Protection Design Guidelines for Electrochemical Energy Storage Stations
These standards are driving the industry toward a complete safety framework covering Battery Cell → Battery Module → Energy Storage System → Energy Storage Station.
International Standards Focus on Thermal Runaway Propagation Testing
International markets place greater emphasis on safety validation under extreme failure conditions.
Standards including:
• NFPA 855 Standard for the Installation of Stationary Energy Storage Systems
• UL 9540A Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems
focus on Large-Scale Fire Testing (LSFT), evaluating whether an energy storage system can control thermal runaway propagation, reduce heat transfer, delay fire spread, and provide additional time for emergency response.
New Challenges for Passive Fire Protection Materials in Energy Storage Systems
1. Higher Thermal Insulation Performance with Thinner Thickness
Battery systems are becoming more compact. Thermal insulation materials must provide extremely low thermal conductivity and effective heat blocking performance within limited installation space.
2. Excellent High-Temperature Stability
During lithium battery thermal runaway, temperatures can exceed 1000°C. Materials must maintain structural integrity and continuous thermal barrier performance.
3. Higher Fire Safety Requirements
Passive fire protection materials should provide non-combustibility, low smoke generation, and stable performance under fire conditions.
