Use of Mica for EV Battery Insulation

An electric battery is the most important component of an electric car and plays a vital role in making your car roll. The car battery, like any battery, needs to be insulated properly. You might have seen your car battery wrapped with a mica car battery insulation pack. It is to insulate your car battery from the rest of the car. Not just that, your car battery needs protection from cold weather and hot weather to protect the vital components of the battery. Mica blankets are used to protect your car battery from harsh weather. 



Why use mica for EV battery insulation?

There are many materials available for car battery insulation, but mica is the most preferred due to the following reasons:

  1. Mica has amazing thermal stability. It is stable up to high temperatures of 1000 degrees Celsius. It can prevent thermal runaway. Mica thermal spacers ensure a safe connection between the cells.    
  2. Mica has amazing dielectric capabilities. It has a dielectric strength of 20 kV/mm. It does not allow the passage of current, which helps insulate the car battery from the rest of the car.  
  3. Mica has exceptional mechanical properties. It can be converted into thin sheets without losing its properties. Thus, it makes mica highly durable.
  4. Mica is flame resistant and chemically inert. Thus, it prevents damage in case of unexpected events by discouraging the spread of the fire. It is also halogen-free and does not produce toxic gasses.   

These are the key reasons why mica is preferred for EV battery insulation. It is also used in a wide range of other automotive and industrial insulation applications.

How is Mica Used for Electric Vehicle Battery Insulation?

Image
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 h...

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, i...

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 accepte...
