Product Description
Nano Thermal Insulation Panel for EV Battery is a high-performance advanced insulation material designed for lithium-ion battery systems, including electric vehicles (EV), energy storage systems (ESS), and high-energy-density battery modules.
It is engineered to function as a battery cell spacer and thermal barrier material, effectively blocking heat transfer between adjacent cells and significantly reducing the risk of thermal runaway propagation inside battery packs.
Compared with traditional silicone foam, mica sheets, and fiberglass insulation materials, the nano thermal insulation panel delivers lower thermal conductivity, higher fire resistance, and thinner structural design, making it ideal for next-generation compact battery systems.
better thermal insulation performance
Much thinner material for the same protection level
price is cheaper
Lower weight
Better vibration resistance
better thermal insulation performance
Higher mechanical strength
Easier for mass production processing
Better thermal insulation performance at 800°C high temperature
Conclusion: Nano thermal insulation panel offers the best balance of thermal protection + mechanical strength + manufacturability for EV battery applications.
Thermal conductivity as low as 0.018–0.030 W/m·K, providing excellent heat blocking performance in high-temperature battery environments.
Available thickness ranges from 1.0mm to 10.0mm, enabling high energy density battery designs with optimized space utilization.
Continuous operation: up to 800°C
Peak resistance: up to 1200°C (material grade dependent)
Excellent thermal stability under extreme conditions
Non-combustible nano composite structure
Helps prevent flame spread between cells
Suitable for UL94 V-0 design requirements
High dielectric strength helps prevent electrical short circuits between adjacent battery cells and modules.
High compression resistance
Maintains thickness under long-term load
Stable performance under vibration and cycling stress
Resistant to electrolyte exposure, humidity, oxidation, and long-term thermal aging.
In lithium battery packs, thermal runaway propagation between cells is one of the most critical safety risks.
Nano insulation panel is designed to act as a cell-to-cell thermal barrier, providing:
Heat isolation between adjacent cells
Delay of thermal propagation chain reaction
Improved battery pack safety performance
Reduced risk of system-level failure
Better compliance with EV safety standards
It is especially suitable for high-energy density battery systems, where spacing is minimal but safety requirements are extremely high.
Nano Thermal Insulation Panel plays a vital role in improving EV battery safety by manage heat transfer within a single battery cell. In lithium-ion battery packs, heat generated from a single failed cell can quickly spread to adjacent cells, leading to thermal runaway propagation and potential system failure. The nano insulation panel helps block and slow down this heat transfer process, giving the battery management system more time to react and shut down the system safely. With its ultra-low thermal conductivity and high-temperature resistance, it significantly reduces fire risk and enhances overall battery pack stability, making it an essential safety material for modern EV and energy storage applications.
