Svenska Aerogel is expanding development and testing of its Quartzene material for use as a thermal barrier in electric vehicle (EV) battery systems. This work supports growing industry demand for passive fire protection and thermal management in lithium-ion battery packs, particularly as safety regulations tighten and energy densities increase.
Quartzene is an engineered porous material based on amorphous silica. It’s designed to interrupt or slow the spread of heat during thermal runaway events, where battery cell failure can lead to chain reactions and fire risk.
The material can be integrated as part of passive fire protection layers in cell-to-cell or module-level insulation designs. Due to its low density, high thermal insulation properties, and compatibility with coatings and composites, it’s being explored for use in pouch and cylindrical cell formats.
During the spring, Svenska Aerogel participated in multiple industry events focused on EV battery design and safety. The company is currently engaged in several customer-driven projects across Europe and North America, where Quartzene is being evaluated as a thermal barrier in new battery architectures.
These projects are focused on improving system-level fire containment without adding significant weight or cost, a key requirement for EVs aiming to maximize performance and safety.
Quartzene can be delivered in powder form or integrated into slurries and coatings, allowing it to be customized for use in gap fillers, compressible insulation pads, or rigid board components. This flexibility enables integration into a wide range of battery pack configurations.
Svenska Aerogel reports growing interest from battery system developers working to comply with evolving safety standards and seeking lightweight, scalable solutions for next-generation EV platforms.
