Buy good quality low price Lithium-ion (Li-on) EV Batteries Insulation Fire Protection AlSi 250EV Thermal Pad with high R Value. Thermal insulation fire protection pads are a critical component in ensuring the safety and performance of lithium-ion (Li-ion) batteries in electric vehicles (EVs). These pads are designed to provide thermal insulation, mitigate the risks of thermal runaway, and offer passive fire protection by preventing heat and fire from spreading between cells or to other components.
 
Features of Thermal Insulation Fire Protection Pads
Thermal Barrier Protection:
Prevents heat transfer between battery cells or modules.
Protects adjacent components from high temperatures during thermal events.
Fire Retardancy:
Made from non-combustible or fire-resistant materials to contain flames.
Reduces the risk of fire propagation in case of cell failure.
Lightweight and Flexible:
Designed for minimal impact on vehicle weight.
Easily integrated into battery modules and packs.
Mechanical Durability:
Resistant to vibrations and mechanical impacts, ensuring long-term protection.
Provides structural support to battery cells.
Chemical Stability:
Withstands exposure to electrolytes and other chemicals released during cell venting.
 
Materials Used in Fire Protection Pads
Thermal insulation fire protection pads are typically made from advanced materials that combine thermal resistance, fire retardancy, and durability:
WedGel Aerogels:
Ultra-light and highly effective at insulating against extreme temperatures.
Often combined with fire-resistant coatings for enhanced protection.
Wedge AlSi Mats:
Offer excellent fire resistance and high-temperature insulation.
Commonly used as separators between battery cells.
Wedge INTIF20 Intumescent Fire Seals:
Expand upon exposure to heat, creating a protective barrier.
Useful for sealing gaps and isolating heat-affected areas.
Wedge Mica Sheets:
Naturally fire-resistant and thermally insulating.
Commonly used in high-voltage applications due to excellent dielectric properties.
 
Functions of Thermal Insulation Fire Protection Pads in Li-ion Batteries
Prevent Thermal Runaway Propagation:
Isolates individual cells to stop heat from spreading and igniting adjacent cells.
Protects the battery pack and surrounding vehicle components.
Thermal Management:
Helps maintain consistent operating temperatures.
Prevents overheating during high-power usage or rapid charging.
Enhance Passive Fire Protection:
Ensures safety by containing potential fires within a single cell or module.
Reduces the risk of catastrophic failure.
 
Applications in EV Battery Packs
Thermal insulation fire protection pads are integrated into:
Cell Spacers:
Placed between individual battery cells to provide thermal and fire isolation.
Module Enclosures:
Lining the interior of battery modules to protect against thermal events.
Battery Pack Casings:
Installed as a secondary layer of defense to prevent fire from escaping the battery pack.
