SOLUNI Technology Investment Joint Stock Company has unveiled a groundbreaking test result in the fire prevention and firefighting industry.
Specifically, FireThief, a water-based firefighting solution utilizing heterogeneous technology, can completely extinguish Lithium battery fires in just 8–11 seconds and prevent reignition.
Amid the rapid growth of electric vehicles and renewable energy, fires caused by Lithium-Ion batteries have become a global concern. Recent incidents involving electric vehicles, energy storage systems, and power banks highlight the industry’s struggle to find effective solutions.
SOLUNI’s announcement of FireThief on October 25, 2025, marks a significant breakthrough for Vietnam. The company claims the solution can halt thermal runaway—a chain reaction that causes batteries to reach temperatures of 1,000°C and continue burning even after being separated from the heat source.
Current firefighting methods like CO₂, dry powder, and foam are largely ineffective against such fires. FireThief, however, leverages multi-mineral heterogeneous technology to rapidly cool the battery while forming a heat-resistant mineral layer that isolates the core, cutting off oxygen and preventing electrode contact.
Tests conducted by SOLUNI in collaboration with T-FIRE demonstrated that the FireThief FT6 (6-liter) model meets the Dutch NTA 8133:2021 standard—an international benchmark for Lithium battery fires. The product also passed tests for solid (1A, 21B) and cooking oil (5F) fires.
SOLUNI has established the TCCS 01:2025/SOL standard to ensure quality control throughout production. Key parameters such as a neutral pH of 7.8, a density of 1.043 g/mL, and low heavy metal content comply with QCVN 07:2009/BTNMT, ensuring user safety and environmental friendliness.
In a market dominated by imported technology, FireThief is hailed as a foundational “Made in Vietnam” innovation, paving the way for a domestic green firefighting industry.
The development of FireThief spanned six years of research and testing. The team continuously adjusted the formula, conducting hundreds of trials, as even minor deviations could destabilize the entire reaction system.
FireThief’s uniqueness lies in its multiphase principle, where multiple substances coexist and synergize under high temperatures.
“In battery fires, most solutions decompose. However, FireThief’s mineral system maintains its structure, creating a permanent barrier between the battery electrodes, eliminating conditions for combustion,” explained Dr. Hương Trần Phương Nam, Director of SOLUNI’s Technology Division.
According to SOLUNI, FireThief is not just a technological product but a symbol of Vietnamese ingenuity in applied science.
The company plans to launch FireThief domestically before 2026, targeting high-risk areas such as residential zones, electric vehicle garages, charging stations, and energy storage centers. Simultaneously, SOLUNI is negotiating with international partners to export the technology, aiming to position Vietnam as a regional hub for green firefighting innovation.
