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.
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.
Which fire extinguishing agent is best for a lithium battery?
According to the evidence, water-based fire extinguishing agents (such as water, AF-31, AF-21, etc.) show a better cooling effect when extinguishing lithium battery fires, and their cooling effect is more significant than that of gas fire extinguishing agents (such as carbon dioxide, heptafluoropropane).
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.
High-quality fire extinguishing agents and effective fire extinguishing strategies are the main means and necessary measures to suppress disasters in the design of battery energy storage stations . Traditional fire extinguishing methods include isolation, asphyxiation, cooling, and chemical suppression .
Can Li-ion battery energy storage systems be used for fire protection?
To develop an appropriate solution for the specific application of managed stationary storage systems it was necessary to conduct a series of experiments and tests. Our work has shown that Li-ion battery energy storage systems can be a controllable application when it comes to fire protection.
Are fire-extinguishing microcapsules safe for lithium metal batteries?
Lithium metal battery (LMB) is regarded as one of the most promising high-energy energy storage systems. However, the high reactivity of lithium metal and the formation of lithium dendrites during battery operation have caused safety concerns. Herein, we present the design and synthesis of fire-extinguishing microcapsules to enhance LMB safety.
