Aerogel Battery Thermal Insulation Sheet

Description

The Aerogel Battery Thermal Insulation Sheet is a high-performance silicon-based nano-aerogel composite material specially developed for power batteries and energy storage systems. It combines SiO₂ aerogel with nano-fiberglass, ceramic fiber, or pre-oxidized fiber materials to deliver excellent thermal insulation, flame retardancy, cushioning, and protective performance in a thin and lightweight structure.

The product can be customized in size and thickness according to different battery structures and application requirements. Three main configurations are available:

• Nano-Fiberglass Battery Thermal Insulation Sheet: customizable thickness from approximately 0.5 to 6 mm
• Ceramic-Fiber Battery Thermal Insulation Sheet: customizable thickness from approximately 1 to 10 mm
• Pre-Oxidized-Fiber Battery Thermal Insulation Sheet: customizable thickness from approximately 1.5 to 7 mm

The insulation pads provide excellent high-temperature resistance and flame-retardant performance. The nano-fiberglass version supports service temperatures up to 800°C in an inert environment, the ceramic-fiber version up to 800°C, and the pre-oxidized-fiber version up to 600°C. All three types achieve a V0 flame-retardant rating and a hydrophobicity rate of over 98%. Depending on the material configuration, thermal conductivity can be as low as ≤0.016 W/(m·K) at 25°C.

Key Benefits

High-Efficiency Thermal Insulation
The unique nanoporous structure of aerogel effectively reduces heat transfer and helps slow thermal propagation between battery cells.

Excellent Flame Retardancy
V0-rated flame-retardant performance enhances battery safety under high-temperature and abnormal operating conditions.

High-Temperature Resistance
Different material configurations withstand operating temperatures of approximately 600–800°C, making them suitable for power battery and energy storage applications.

Thin & Lightweight Design
High thermal resistance can be achieved with relatively low material thickness, helping optimize internal battery-pack space.

Cushioning & Impact Resistance
When installed between cells, modules, and battery housings, the material provides thermal insulation together with cushioning and shock-resistant protection.

Customizable Solutions
Dimensions, thicknesses, and material configurations can be customized to meet specific customer and application requirements.

Applications

The thermal insulation material can be installed between battery cells, between cells and modules, and between modules and battery housings. Its combination of thermal insulation, flame retardancy, and shock resistance helps reduce safety risks associated with battery thermal runaway. It is suitable for power batteries, energy storage batteries, wearable devices, mobile devices, and other lithium-battery applications.

Typical applications include:

EV Battery Packs | Energy Storage Systems | Consumer Lithium Batteries | Wearable & Mobile Devices
