Building on this analysis, this paper summarizes the limitations of the existing technologies and puts forward prospective development paths, including the development of multi-parameter coupled monitoring and warning technology, integrated and intelligent thermal management technology, clean and efficient extinguishing agents, and dynamic fire suppression strategies, aiming to provide solid theoretical support and technical guidance for the precise risk prevention and control of lithium-ion battery storage power stations.
The study also summarizes the limitations of current extinguishing agents for suppressing lithium battery fires and the shortcomings of extinguishing strategies, offering several methods for improving the performance of extinguishing agents.
Lithium ion battery and fire extinguishing application The batteries used in this study are the commercial large-scale LIBs (27 ∗ 148 ∗ 115 mm) with LiFePO 4 (LFP) and graphite as cathode and anode. The nominal capacity and voltage are 52 Ah and 3.65 V, respectively.
However, manufacturing defects or non-compliance with safety norms can easily trigger thermal runaway in lithium batteries, leading to safety accidents such as fires and explosions. This highlights the urgent need for advanced lithium battery fire suppression technology.
Based on the understanding of fire extinguishing mechanism, new fire extinguishing agents have been developed for battery fires, such as hydrogel fire extinguishing agents and liquid nitrogen fire extinguishing agents.
With the advantages of high energy density, short response time and low economic cost, utility-scale lithium-ion battery energy storage systems are built and installed around the world. However, due to the thermal runaway characteristics of lithium-ion batteries, much more attention is attracted to the fire safety of battery energy storage systems.
Is lithium ion battery a fire hazard?
Standard on Clean Agent Fire Extinguishing Systems (2018 Edition) Abstract Lithium-ion battery (LIB) carries an inherent risk of thermal runaway (TR), which may result in off-gassing (flammable, toxic, or explosive), fires, and explosion.
