Mica has high insulating properties and is even used for protecting furnaces. It can withstand temperatures up to 1000℃ and voltages up to 2000V. It absorbs little moisture and is resistant to most elements making it ideal for the thermal insulation of EV batteries.
Mica sheets and laminates can be used to separate cells in an EV battery and even keep it away from the rest of the vehicle. They are available as sheets of varying thickness and are placed in between the cells of the battery. The insulating properties of mica prevent the propagation of the reaction throughout the battery and prevent further damage before it can be controlled.
