Advanced Thermal Insulation And Sealing Solutions for Electric Vehicle Batteries: Unveiling Cutting-Edge Materials And Technologies

Regarding the sealing of the battery module and cooling solutions for electric vehicle batteries, here are some key differences and advantages of the materials mentioned:

1. Silicon foam for battery casing sealing:

- Low density

- Sound insulation

- Vibration damping

- Thermal insulation

- High flame retardancy

- Aging resistance

- Super waterproof

- Super dustproof

- Lightweight

- Insulation

- High and low-temperature resistance

- Longer service life compared to traditional foam materials

- Better comfort, foam density, and environmental protection than traditional foam materials

2. Mica sheet for cooling pads in pouch cell battery packs:

- Excellent anti-high-pressure and high-temperature resistance

- Can endure temperatures up to 1300°C for a certain period without burning through

- Provides crucial time for passengers to evacuate during fire incidents or accidents, ensuring safety

3. Silicone foam gasket for cooling pads in pouch cell battery packs:

- Comparable flame retardancy and insulation to mica sheets

- Additional advantages include vibration damping, anti-high voltage, and maximum protection for each battery's independent space

4. PU+PET for cooling pads in pouch cell battery packs (less recommended):

- Inferior fire insulation compared to the previous options

- Fading out as a popular choice

- Cost-effective but may compromise safety and battery life

5. Different solutions for prismatic cell battery packs:

- MPP (Microcellular Polypropylene foam):

 - High-temperature resistance

 - Excellent insulation properties

 - Reduces heat transfer and improves battery performance

 - Provides pressure resistance and shock absorption for battery protection

- Silicone rubber:

 - Low thermal conductivity

 - High ignition temperature and low flammability

 - Resistance to various chemicals

 - High tensile strength and durability

 - Recyclable and biodegradable, reducing environmental impact

- Ceramic Silicone Rubber:

 - Contains all the advantages of silicone rubber

 - Forms a ceramic layer under flame burning, maximizing escape time for passengers

- Aerogel pad:

 - Low thermal conductivity, effectively blocking heat transfer

 - Withstands high temperatures without losing insulation performance

 - Thin and lightweight, adaptable to different cell shapes and sizes

 - Provides thermal protection and mechanical support to cells

6. Silicone rubber  prismatic cell venting seal:

- Stable and heat-resistant

- Provides support and protection for thermal management

7. Composite materials (PU, RPU, FPU) for battery base cooling plate:

- High strength and corrosion resistance

- Suitable for load-bearing and corrosion-resistant environments in water-cooled plates

These differences highlight the unique properties and advantages of each material in terms of insulation, protection, heat resistance, flame retardancy, durability, and safety for electric vehicle batteries.
