How is Mica Used for Electric Vehicle Battery Insulation?

Electric vehicles are the future. The ban on petrol and diesel vehicles is going to roll out by 2030. Thus, the transition to electric vehicles is inevitable. Electric vehicle technology is still in the early stages and thus expensive. 


Apart from making efficient battery systems, manufacturers need to ensure that electric vehicle battery systems are safe. The electric vehicle battery pack needs to be insulated thermally and electrically to ensure safety. In this post, we will look at how mica material is used for electric vehicle battery insulation.

 Mica Battery Pack Insulation 

Mica battery pack insulation is used as a high-temperature incombustible barrier around battery packs and to electrically insulate the battery pack from other critical components of an electric vehicle. Axim Mica mica car battery pack insulation comes with the UL-94 rating and CE and ROHS certifications. You can partner with Axim Mica to design a customized battery pack insulation. Axim has been a Tier 1 supplier to the big three American Automotive manufacturers since 2005. 

Mica Compression Pads

Mica compression pads are used within the battery pack to ensure safe thermal and electrical connections. Thermal runaway is the process where lithium-ion cells enter an uncontrollable and self-heating state. It is a common risk related to lithium-ion batteries. 

Mica compression pads are used to prevent the risk of thermal runaway. Mica compression pads slow down the time of thermal propagation, which buys time for the driver and passengers inside the electric vehicle to get out of the car in case of an accident.     

Flame retardant barrier

Mica blankets are used as flame-retardant barriers in electric vehicles. The electric battery pack contains electrolyte liquid which is prone to fire when heated up. Mica blankets are used for the thermal and electrical insulation of the mica car battery pack. It helps prevent the spread of fire in case of accidents.     

These are the three primary ways mica insulation products are used for electric vehicle battery insulation. If you are looking for a reliable manufacturer of mica electrical and thermal insulation solutions for the automotive industry, you can get in touch with Axim Mica.

A Short Guide on Two Popular Types of Mica Sheets!

Image
Mica is a naturally occurring material that comes in 37 different varieties.  However, only two forms of mica—phlogopite and muscovite—out of the 37 variants are utilized for industrial insulating purposes. Although they come in sheet form, they must first be transformed into powder before being used to create a variety of mica industrial insulation products. Each of these two forms of mica has characteristics that make them suited for a variety of uses in numerous sectors. Read out the below blog to learn about two popular types of micasheets . Types of Mica sheets   Phlogopite Mica Sheets:   The mica sheets that remain stable up to 900°C are known as phlogopite mica sheets. They come in both flexible and rigid forms. The thermal insulation properties of phlogopite mica sheets are different from muscovite mica sheets. Phlogopite mica, out of all the different types of mica, offers the best thermal insulating properties. There are a variety of colors, including amber

What is the role of safety certifications of mica sheets in the industry?

Image
Mica sheets are used in various industries for thermal and electrical insulation applications. They are used at high operating temperatures up to 1600 degree cel sius and in high voltage environments. Therefore, it is very important to ensure that mica sheets are safe for use. That’s where the role of  mica sheets  comes into play. The certifications are gained by rigorously testing the product under controlled conditions. Regarding mica sheets, the UL rating is the global industrial safety standard.  Other region-specific fire resistance classifications, such as BS 479 (class 1) and NBN 21-203 (A1), are also used to approve thermal and electrical insulation products. In this post, we will focus on the UL-rating of mica sheets. What are UL standards for safety? UL is a global safety certification company that certifies a wide range of products used in both industrial and commercial applications. If a product is listed or UL certified, the product is globally accepted as safe for
