4 High Performance Thermal Barrier Materials for EV Battery

Posted by Katie Sullivan

Thermal Runaway Propagation Prevention with Thermal Barrier Materials
Hybrid and battery electric vehicles that use lithium-ion cells require that these cells are maintained at specific ambient temperatures. "Thermal runaway" occurs as a result of the rapid rise in temperature within one of the battery cells. One of the greatest challenges for battery design engineers is to manage heat. For this reason, batteries are designed with thermal management systems that provide different levels of protection, including cell-to-cell, module-to-module, and pack level.

Marian provides custom flexible die cut solutions that are incorporated into battery design at the cell, module and pack level to aid with thermal management. These die-cut parts are made with high temperature resistant materials (also known as flame barrier materials) that are designed to offer thermal insulation to delay the onset of thermal runaway.

The Best Thermal Gap Pad for Your Design

Posted by Katie Sullivan

July 29, 2020 9:30 AM

Thermal gap pads are one common type of thermal management materials and are utilized in electronic devices within the interface, or gap, between a heat generating component and a heat sink. The heat sink or cooling plate is designed to conduct heat away from the heat generating component to keep it cool and running safely.

According to Parker Chomerics Thermal Management Engineering Handbook, the typical contact area between most semiconductors and heat sinks can be made up of 90% air voids! We also know that air is about 200 times less conductive than a 5 W/mK thermal interface pad. This is where the thermal gap pad comes in.

Thermal gap pads are made of soft polymer that flows into the air gaps in the interface to aid in the more efficient and effective conduction of heat.

4 Insulating Materials for use in EV Batteries

August 27, 2019 9:00 AM

Improvements are being made to the lithium-ion batteries used in electric vehicles. Car makers are developing more powerful lithium-ion batteries that have increased range and charge more rapidly. Along with these improvements, enhancing safety is becoming increasingly urgent for electric vehicle development.  As mentioned in our previous blog post, 11 Considerations when Selecting Thermal Interface Materials for Electric Vehicle Li-Ion Batteries, Li-ion batteries produce a significant amount of heat while in use and while charging. Along with the use of thermal management materials, placing 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.

In this post, we outline four materials that can enhance the safety of lithium-ion batteries used in electric vehicles.  Some shared characteristics of these four materials are listed below. 

  • ultra-thin
  • lightweight
  • electrically and thermally insulating
  • flame retardant
  • can be die-cut and laminated with PSA

Video Demo: Thermal Resistivity and Conductivity of Silicone Foam

Thermal resistivity and thermal conductivity can be two very important physical features of foam materials for certain applications. Most devices containing electronic components must be designed to deal with heat in one way or another. Electronic circuitry operates most reliably at lower temperatures. High operating temperatures decrease the service life of the device or module. It is critical for designs to either conduct or isolate heat away from delicate components to ensure ideal operating temperatures.

Thermally Conductive Materials in LED Assemblies

Although LEDs are considerably more efficient than traditional lighting forms, they do still produce heat. This heat can have an adverse effect on the LED and therefore must be managed to ensure the true benefits of this technology are realized. If excessive junction temperatures are reached, particularly above the maximum operating temperature of the LED (~120-150˚C), a non-recoverable effect could occur, leading to complete failure. Operating temperature is directly related to the lifetime of the LED; the higher the temperature, the shorter the LED life.
