What is a thermal barrier in a HEV / EV battery?

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. In this blog post, we take a look at 4 thermal barrier materials designed for use in HEV / EV Battery to aid with thermal runaway prevention.

How do battery PADs work?

Typically, this is addressed by dielectric compression pads, deployed between cells to maintain pressure and keep connections secure while still allowing the battery to breathe. These pads also provide thermal insulation between cells, thereby directing heat from a cell toward a heat sink and providing basic thermal management.

How important is battery pack protection?

Even more critical to battery pack protection is the need to ensure safety, specifically in the event of a thermal runaway. Thermal runaway occurs when a thermal event propagates from cell to cell, creating a cascade — and ultimately, an explosion.

Can thermal barrier materials prevent cell-to-cell thermal runaway propagation?

In view of the limited literature on the usage of commercially available thermal barrier materials in the battery pack to prevent cell-to-cell thermal runaway propagation, we characterize the thermal performance of different materials and the usage of selected materials in a battery pack-level overheating test.

What are battery modules & compression pads?

Battery modules are the next “level” of battery constructions and are created when multiple cells are packaged together. This is true for all types of battery cells. Compression pads – Similar to the cell level, compression pads insulate individual battery modules.

How do compression pads help in thermal runaway protection?

Compression pads also aid in TRP by helping to block or isolate thermal runaway, reducing heat-generating friction, and protecting cells against impact which can damage them and cause spark or shorting issues. Flame barrier materials – Thermal runaway protection solutions are rarely a single component or material.
