China Implements World's Strictest Mandatory Battery Safety Standard, Industry Moves Toward an Era of "Inherent Safety"

Core Summary
Effective July 1, 2026, the highly anticipated mandatory national standard "Safety Requirements for Traction Battery of Electric Vehicles" (GB 38031-2024) will be officially implemented. This new standard imposes the world's most stringent requirements for battery thermal runaway safety—after a battery cell undergoes thermal runaway, the battery system must guarantee "no fire, no explosion." This marks the official transition of China's power battery safety standards from "risk management" to a new regulatory phase of "inherent safety," profoundly reshaping the industry's competitive landscape.

Core Requirements of the New Regulation

"No Fire, No Explosion" Becomes the Mandatory Baseline: The new national standard eliminates the previous version's "5-minute" escape time requirement for thermal runaway propagation, directly upgrading it to "no fire, no explosion." This represents the ultimate test of battery system safety throughout its entire lifecycle.
Forward Shift of Safety Responsibility: The standard compels enterprises to undertake fundamental innovation at the most upstream stages, including cell chemistry systems, structural design, and thermal management systems, rather than relying solely on remedial measures like insulation and alarms in later stages.
Alignment with and Leadership in International Standards: Regarding the core indicator of thermal runaway safety, the national standard implemented by China is already at the global leading level and is expected to become a new benchmark in the field of global power battery safety.

Industry Impact

Significant Increase in Technical Threshold: Enterprises lacking core safety technology capabilities will be phased out more rapidly, with industry resources concentrating toward technologically leading companies.
Acceleration of Technology Iteration: This will greatly propel the R&D and commercial application of high-stability electrolytes (e.g., solid-state/semi-solid-state), high-safety anode materials, and advanced thermal management and early warning technologies.
Boosting Consumer Confidence: The mandatory force of the regulation will fundamentally prevent products with safety hazards from entering the market at the source, laying a solid foundation for the long-term healthy development of the new energy vehicle market.

As a deep participant in the industry's development, we fully support and actively respond to this milestone standard upgrade. We will continue to increase investment in safety technology R&D, providing customers with products that meet higher safety standards exceeding regulatory requirements.
