The thermal spreading interval between the thermal runaway battery and the neighboring batteries in the module is increased to an infinite length, and only the thermal runaway battery shows the phenomenon of spraying valve such as fire and smoke. It is expected to have a guidance for the design of thermal insulation in lithium-ion battery modules.
Therefore, this paper summarizes the present or potential thermal hazard issues of lithium batteries (Li-ion, Li–S, and Li–air batteries). Moreover, the corresponding solutions are proposed to further improve the thermal safety performance of electrochemical energy storage technologies.
Abstract. Thermal runaway is the main cause of lithium-ion battery accidents. Once a single battery occurs the thermal runaway, the whole battery pack will have the risk of explosion. Adding an insulating layer between the batteries and the module can reasonably and effectively inhibit the thermal runaway diffusion.
Compared with the use of nanofiber insulation layer, the thermal spreading between lithium batteries in the module is completely suppressed by the use of composite phase change insulation layer. The goal of zero spreading of thermal runaway within the module has been realized.
The results showed that the use of thermal insulation layers can effectively inhibit the thermal spread in the battery module. The average spreading time of each cell in the module with nanofiber insulation increased by 5.27 and 7.36 times, compared with that of the module without insulation.
However, since the implementation of electric vehicles, there have been a number of lithium-ion battery fire, explosion and other accidents in electric vehicles, mainly due to the thermal runaway of lithium-ion battery .
