The rapid advancement of the electric vehicle (EV) market is no secret, and to keep pace with this progress, OEMs seek cutting-edge thermal management solutions that perform well and come at a reasonable cost.
Among essential materials used for heat management in EV batteries, thermal gap fillers play a crucial role. Marian collaborates with suppliers like Polymer Science, whose partnership allows for development of high-quality gap filler materials along with various other essential materials for managing heat in electric vehicles.
We sat down with John Biddle, Vice President of Product Development at Polymer Science for a Q&A session where we delved into their contributions to the production of thermal management material and the benefits they bring to the EV world.

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.

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

11 Considerations When Selecting Thermal Interface Materials for Electric Vehicle Li-ion Battery
Currently, lithium-ion (li-ion) batteries are the most common type of battery used to power electric vehicles. Today's market is demanding that batteries charge faster and last longer. Because li-ion batteries produce significant heat when in use and charging, thermal management is critical. Excessive heat can cause irreparable damage to the battery.
