Thermal and Electrical Insulation. There are two types of insulation to consider: Thermal insulation makes sure that the battery pack, cells, and modules can withstand high temperatures to avoid overheating; Electrical insulation means that EV battery parts can deal with a defined voltage without causing any failures.
The main advantage is related to the thermal insulation, which is fundamental to interrupting the chain reaction that triggers the fire and explosion of the battery pack [5], [51]. Indeed, while the paraffin module reached a maximum temperature of 79.6 °C and a temperature difference of 35.6 °C, the glass fibres plus paraffin achieved a maximum temperature of 71.9

As one of the core components of electric vehicles, Li-ion batteries (LIBs) have attracted intensive attention due to their high energy density and good long-term cycling stability. However, some abuse conditions inevitably occur during battery operation, resulting in safety accidents such as the thermal runaway (TR) of LIBs. Therefore, the efficient and appropriate

Li-ion batteries perform best when maintained within an optimal temperature range. The challenge is exacerbated by the consumer''s desire for a rapid charge and discharge, both of which add to heat management issues. Too hot or too cold and thermal instability can occur leading to thermal runaway that can at best destroy the cell and at worst start a vehicle fire.
Polyester Films (also known by the DuPont trade name Mylar®) are also found in many applications where electrical insulation, thermal resistance, and dimensional stability are required. PET films are useful as a

Propagation from the cells in the center of the pack is most likely because there are more heat-transfer paths to neighboring cells. For this reason, it is very important to isolate a cell from others in the battery pack once it begins to go into TR, via thermal insulation and cooling and by breaking the electrical contacts to the cell. The
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.
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.
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.
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.
