Recent advancements in the research on lithium-ion battery safety have significant implications for the construction industry, particularly as these batteries become increasingly integral to modern machinery and tools. The study, led by Wang Shuang from the State Key Laboratory of Explosion Science and Technology at the Beijing Institute of Technology, highlights critical safety risks associated with lithium-ion batteries that could affect their widespread adoption in various sectors, including construction.
As the demand for sustainable energy solutions grows, lithium-ion batteries are favored for their long cycle life, high capacity, and environmental friendliness. However, the paper published in ‘工程科学学报’ (Journal of Engineering Science) underscores a growing concern: the safety risks tied to thermal runaway and capacity degradation under extreme conditions. “When the internal temperature of the battery reaches about 120°C, an exothermic reaction begins,” Wang explains. This reaction can lead to spontaneous thermal runaway, producing hydrogen and alkane gases that pose serious combustion and explosion risks.
For construction companies relying on battery-operated tools and equipment, these findings are particularly relevant. The paper outlines how the thermal stability of the battery’s electrolyte is influenced by both the lithium salt and the organic solvent used. As construction sites often operate under varying temperature conditions, understanding these risks is crucial for ensuring worker safety and equipment reliability.
Moreover, the research delves into effective fire-extinguishing measures, revealing that agents like heptafluoropropane and water outperform traditional carbon dioxide and dry powder extinguishers. This knowledge could guide construction firms in selecting appropriate safety equipment to mitigate risks associated with lithium-ion battery fires.
The increasing number of safety-related incidents involving lithium-ion batteries, as noted in the study, emphasizes the need for the construction sector to adopt stringent safety protocols and invest in research-backed solutions. Wang’s research also points to future directions that could reshape how these batteries are utilized in construction. The exploration of new electrolytes and high-efficiency fire-extinguishing mediums could lead to safer, more reliable battery technologies.
As the construction industry continues to embrace innovative energy solutions, the insights from Wang Shuang’s research could serve as a catalyst for developing safer practices and technologies. The potential for enhanced safety and performance in lithium-ion batteries not only protects workers but also fosters greater confidence in adopting these technologies across the sector.
