Comparative Evaluation of Organic Acid Salt/Oxidizer Fire Suppressant Mixtures with Various Compositions

Abstract. In recent years, fire incidents involving lithium-ion batteries (LIBs) have increased, often resulting in significant damage due to thermal propagation between cells and the risk of re-ignition. This study aims to develop novel self-activating fire suppressants composed of oxidizers and fuels, which release fire-extinguishing species upon combustion or thermal decomposition triggered by overheating. Mixtures were prepared using various organic acid salts combined with oxidizers such as potassium periodate and potassium perchlorate. By varying component ratios and particle sizes, we evaluated their effects on combustion behavior and fire suppression performance. Combustion temperature and other thermal properties were also measured to investigate their correlation with extinguishing efficiency.
