Levron Aerogel develops advanced aerogel-based thermal materials engineered for electric vehicle battery safety — compact pack integration, passive fire barrier strategies, and high-performance thermal protection across next-generation EV platforms.
EV platforms are among the most thermally constrained engineering environments in modern transportation. Energy density, safety, packaging, and weight targets create material requirements that conventional insulation cannot meet.
In tightly integrated battery architectures, a single cell failure can generate 400–1000°C temperatures within seconds. Without adequate passive barriers, heat transfers through direct contact, conduction pathways, and gas-phase mechanisms to adjacent cells and modules.
Cell-to-pack and cell-to-chassis designs minimize dead space. Thick conventional insulation directly competes with energy density, cooling infrastructure, and structural requirements — creating engineering trade-offs that compromise either safety or performance.
In a battery system with hundreds of cells, every gram of barrier material per cell becomes kilograms of added vehicle mass. Lightweight protection directly impacts range, efficiency, and overall vehicle dynamics.
Materials must maintain full thermal, structural, and barrier performance over the vehicle's lifetime — through temperature cycling, vibration, humidity exposure, and mechanical stress without degradation.
Battery systems require more than general insulation. Localized thermal failure can escalate into a broader pack-level event. Passive thermal protection built into the architecture is the most reliable path to safer system behavior.
Passive barriers function continuously — without sensors, power, or intervention. They represent the most reliable safety layer in any battery architecture, active under all conditions.
Dividing the battery into thermally isolated compartments ensures that a failure in one zone does not cascade to adjacent cells, modules, or pack-level systems.
High-performance thermal barriers extend the time between initial cell failure and adjacent cell thermal elevation — providing critical minutes for cooling systems, evacuation, or event containment.
Effective safety materials must work within real pack constraints — not require excessive thickness, special handling, or compromises to adjacent system design. Integration feasibility is part of the safety strategy.
Battery pack architecture is one of the most space-constrained engineering environments in automotive design. Every millimeter allocated to thermal protection is a millimeter taken from energy density, range, or cooling infrastructure.
Thick thermal barriers consume valuable packaging space — reducing energy density and limiting design freedom for cooling channels, structural elements, and bus bar routing.
In a 96-cell pack, every gram of barrier material per cell becomes 96 grams of added mass. Lightweight protection directly impacts vehicle range and efficiency.
The barrier must withstand extreme thermal events (400°C+ cell failure, 350°C+ gas venting) while maintaining structural integrity — thin does not mean weak.
Materials that absorb moisture lose insulation efficiency over time. In sealed battery environments, long-term hydrophobic stability is critical for reliable performance over the vehicle's lifetime.
Levron Aerogel is not a commodity insulation product — it is a thermal material platform designed for integration into multi-zone EV battery safety architectures.
Function continuously without power, sensors, or active control — the most reliable protection layer in any EV safety architecture.
Divides the battery into thermally independent zones — containing events and preventing system-wide cascade failure.

Multiple product formats — felt, sheets, granules, custom composites — matching different protection zone requirements within a single material platform.
Different EV protection zones require different material formats. Levron's product platform offers multiple pathways — from standard products to custom-engineered solutions for specific battery architectures.
