HiTHIUM Achieves Milestone with World's First All Open-Door Large-Scale Fire Test

On June 5, 2025, in Xiamen, China, HiTHIUM, a prominent global energy storage technology company, successfully conducted the world's first large-scale fire test of its ∞Block 5MWh battery energy storage system (BESS) with all doors open. This groundbreaking accomplishment establishes a new standard for safety validation, setting a significant milestone in the energy storage sector worldwide.

HiTHIUM Achieves Milestone with World's First All Open-Door Large-Scale Fire Test

As concerns about thermal runaway and other safety risks in BESS continue to rise, there is a growing need for more stringent and standardized safety testing. To address this, the open-door fire test was created, designed to tackle four critical ultimate challenges:

· All open-door combustion: The container doors were left fully open throughout the test, creating an uncontrolled combustion environment with heightened oxygen flow—far more extreme than traditional closed-door tests.

· Dual 15cm extreme spacing: The BESS units were positioned side by side and back to back with only 15cm of spacing. Despite flames exceeding 1300°C, no thermal propagation was observed, demonstrating effective close-range isolation.

· Fire suppression system deactivated: All fire suppression systems were turned off, and the system relied entirely on passive fire protection to endure prolonged intense heat, proving its autonomous fire resistance and reliability.

· 100% State of Charge (SOC): The BESS was tested at full charge to maximize thermal energy release, confirming the system’s reliability and stability in the harshest conditions.

The test, conducted by UL Solutions—a globally recognized safety certification authority—and observed by certified U.S. fire protection engineers and customers, fully complied with UL 9540A and NFPA 855 safety standards.

Despite enduring 15 hours of continuous combustion, the system’s structure remained intact, with no fire propagation to any of the three adjacent containers. This outcome validates HiTHIUM’s multi-layered passive safety architecture and its exceptional thermal isolation capabilities, even in the most extreme conditions.

This milestone underscores HiTHIUM’s dedication to innovation and quality, offering valuable insights for shaping future safety standards in the industry. Moving forward, HiTHIUM will continue to lead in safety performance through technological advancements and global collaboration, guiding the industry toward a safer and more reliable future.
