Combined with reinforced fiberes, like glassfiber or ceramic fibers, Nano Aerogel sheet covered with PET foil is ideal for battery thermal management. Now they are mainly used to be the battery cell-to-cell thermal barriers for the purpose of fire prevention and heat insulation caused by thermal runaway of battery cells in new energy vehicle battery packs.
The thickness and size of the aerogel thermal barrier core sheets can be customized.
Extremely low thermal conductivity: 0.013~0.021W/mK
Super thin thickness: 0.5mm~5mm
Flame retardant: V0 (UL94)
Environmentally friendly ROHS (2011/65EU)
Discover premium aerogel sheets engineered for new energy vehicle (EV) batteries and energy storage systems (ESS). Our reinforced aerogel thermal insulation sheets, combined with glass fiber or ceramic fibers and encapsulated in PET foil, deliver ultra-thin, high-performance cell-to-cell thermal barriers. They effectively prevent thermal runaway propagation, enhance battery safety, and support higher energy density packs.
Ideal for lithium-ion battery thermal management in pouch, prismatic, and other cell formats, these aerogel pads provide exceptional heat insulation, flame retardancy, and mechanical resilience—critical for passive fire protection in high-voltage battery packs.
Ultra-Low Thermal Conductivity: 0.013–0.021 W/m·K — far superior to traditional insulators, allowing thinner profiles while blocking heat transfer.
Super Thin & Lightweight: Custom thicknesses from 0.5mm to 5mm, minimizing space impact and maximizing battery energy density.
Superior Flame Retardancy: UL94 V0 rated, withstanding extreme temperatures to delay or stop thermal runaway spread.
Dust-Free & Durable Design: PET foil encapsulation prevents aerogel powder shedding; reinforced fibers ensure compression resilience and long-term stability.
Environmentally Compliant: ROHS (2011/65/EU) certified, non-toxic, and suitable for automotive applications.
Custom Solutions: Tailored sizes, thicknesses, and configurations for your battery module or pack designs. OEM/ODM supported.
Proven Performance in Thermal Runaway ScenariosWhen one cell experiences thermal runaway (temperatures exceeding 800°C), our aerogel sheets act as robust barriers, creating significant temperature gradients (hundreds of °C) between cells. This breaks the domino effect, providing precious time for safety systems and protecting passengers, vehicles, and adjacent cells.
EV Power Battery Packs: Cell-to-cell insulation in new energy vehicles for enhanced safety and performance.
Battery Modules & Packs: Thermal management for LFP, NMC, and emerging solid-state chemistries.
Energy Storage Systems (ESS): Fire protection in stationary battery installations.
Other: High-energy-density applications requiring lightweight, flexible thermal barriers.
Material: Silica aerogel + reinforced fibers (glass/ceramic) + PET foil
