Do lithium ion batteries need thermal insulation?
Lithium-ion batteries generate a significant amount of heat during operation and charging. In addition to using thermal management materials to dissipate heat, using protective, flame-retardant insulation materials between the battery cell, module, and battery components can provide further thermal and electrical insulation protection.
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.
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.
How to choose a thermal insulation material for Li-ion batteries?
The first thing we need to consider when choosing a thermal insulation material for our Li-ion Batteries is its ability to keep heat away from the cells inside it. This means that if the insulation material has good thermal conductivity then it would be able to transfer heat out of the cell easily.
How to reduce thermal spread between lithium batteries?
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.
What insulating materials should a battery cell use?
Along with the use of thermal management materials, p lacing protective engineered flame-retardant insulating materials between the components of the battery cell, module, and pack can offer additional thermal and electrical insulating protection. However, adding such materials can be challenging due to space and weight constraints.
