6 FAQs about [New energy battery insulation structure]

What is thermal insulation in lithium-ion battery modules?

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.

How does thermal insulation affect a battery module?

The thermal spreading interval time between the first and second batteries in the battery module was increased to an infinite length, when the composite phase change type thermal insulation layer was used. The zero-spreading effect of thermal runaway in the battery module was achieved.

Does thermal insulation protect lithium-ion batteries from thermal runaway propagation?

Thermal runaway propagation tests showed that the use of high-strength thermal insulation hydrogel with 2 mm and 4 mm filler as thermal insulation material effectively suppressed TR and TR propagation of model 18,650 lithium-ion batteries compared to unprotected battery packs.

Does thermal insulation affect the thermal spreading process of lithium-ion battery modules?

And the effects of six different materials of thermal insulation layer on the thermal spreading process of lithium-ion battery modules were investigated. The results showed that the use of thermal insulation layers can effectively inhibit the thermal spread in the battery module.

Can a nanofiber thermal insulation layer be used for lithium battery insulation?

This paper can provide guidance for the design of insulation between lithium battery modules in distributed energy storage systems. The experimental results showed that: The thermal runaway spreading time of the batteries was effectively prolonged, when a nanofiber thermal insulation layer was used.

Can nanofiber thermal insulation extend the thermal spreading time of a battery?

The use of nanofiber thermal insulation layers can effectively extend the complete thermal spreading time of the battery module and the average thermal spreading time of each battery, comparing with the module without thermal insulation layer (No.1 experiment). To a certain extent, it can inhibit the spread of thermal runaway in the module.
