Thermal Runaway Protection Materials | Relats BPM

As battery systems deliver more energy in less space, the margin for error shrinks. Relats introduces BPM a new portfolio of advanced battery protection materials engineered for thermal runaway protection, fire-resistant barriers, and electrical insulation across every level of the battery architecture.

A Different Kind of Battery Safety Challenge

As battery technologies continue to evolve, engineers face an increasingly complex challenge: designing systems capable of delivering higher energy density without compromising safety. Whether in electric mobility, stationary energy storage, industrial equipment, or other battery powered applications, one failure mode has become the defining engineering priority.

 

Thermal runaway.

 

When a cell enters an uncontrolled exothermic reaction, the problem changes in nature, not just in magnitude. Conventional thermal management is designed to keep batteries within their optimal operating temperature.

That objective no longer applies once thermal runaway propagation begins. The engineering goal shifts entirely: prevent heat propagation between cells, maintain electrical insulation under extreme conditions, protect adjacent components, and preserve system integrity long enough to matter.

The objective is no longer temperature regulation. It is mitigating what happens when temperature regulation has already failed.

This requires materials that perform differently, not just materials that perform better. That is the engineering problem behind the new Relats BPM portfolio of battery fire protection materials.

A Complete Portfolio for Battery Protection

Rather than developing isolated products, Relats has engineered a complete family of materials designed to work together throughout the battery pack. Each solution has been developed to address specific engineering challenges while contributing to the overall protection strategy. The Battery Protection Materials portfolio includes solutions for:

• • • Thermal insulation between battery modules
    • Thermal runaway protection
    • Fire-resistant barriers
    • Electrical insulation for high-voltage components
    • Battery pack sealing
    • Cushioning and shock absorption
    • Mechanical protection for critical interfaces

Together, these materials help engineers improve battery safety while supporting increasingly demanding battery architectures.   Download the BPM Technical Guide

Engineered for Multiple Battery Applications

Electric mobility has been the primary catalyst for innovation in battery safety materials. But the engineering challenge of thermal runaway is not exclusive to automotive. Wherever high-energy battery systems operate under thermal or electrical stress, the same fundamental protection requirements apply. The BPM portfolio is designed for engineers working across:

• • • Electric Vehicles (EV / HEV)
    • Energy Storage Systems (ESS / BESS)
    • Industrial Electrification
    • Off-highway Equipment
    • Robotics and Automation
    • Marine Applications
    • Aerospace
    • Electrified Platforms

If your system has a battery and that battery must operate safely under demanding conditions, the thermal runaway protection chain matters. BPM was built for that chain.
