On July 14, 2025, an explosion occurred at the Kaohsiung plant of Molie Quantum Energy, a subsidiary of Taiwan Cement Group, injuring 16 people. The fire spread on site and drew significant public attention. The incident once again highlights the extreme danger of thermal runaway risks in lithium battery production and energy storage systems.
As Taiwan’s leading provider of blast-resistant building technologies, Liansuo Construction Technology leverages FM Approved explosion vent wall and blast wall solutions to deliver highly targeted, high-protection safety upgrades for the industry. These solutions have been successfully applied for international clients such as CATL, with significant results that set a benchmark for the field.
Thermal runaway risk analysis: The hidden peril behind high energy density
Ternary lithium batteries offer high energy density and fast charging performance, but during manufacturing and storage they are highly susceptible to thermal runaway triggered by overheating, short circuits, or chemical reactions, instantly releasing large volumes of combustible gases. Without pressure-relief systems and explosion-resistant structures, gas accumulation can quickly form explosive mixtures, leading to structural failure and casualties.
This Molie Quantum Energy explosion shows that even with advanced production technologies, the risks cannot be fundamentally eliminated without integrated explosion-proof building design. Liansuo Construction Technology notes that only by adopting FM Approved standards and Damage Limiting Construction (DLC) designs can deflagration damage be reduced at the source, achieving insurability and effective disaster mitigation.

Success case: Blast-proof upgrades for a CATL battery plant
Liansuo Construction Technology has implemented FM Approved explosion vent walls and fire- and blast-resistant walls in the blast zoning design for CATL, the global battery leader. Under thermal runaway conditions in a battery test room, the system successfully triggered the vent walls, effectively channeling and relieving pressure, preventing escalation and production interruptions. The project received high praise from the client and insurers. This real-world validation demonstrates the maturity of the technology and proves that Liansuo can offer timely, effective professional solutions for incidents like the Molie Quantum Energy case.
Conclusion: Prevent risks with technology, secure the future with standards
Given that thermal runaway and explosion risks have become a persistent reality for the industry, explosion-proof building design is no longer optional—it is essential for business continuity and personnel safety. Liansuo Construction Technology will continue advancing the application of FM Approved standards and technical innovation to help the battery and energy storage sectors build truly deployable explosion-proof facilities.
