Advantages

• Improves low-temperature discharge performance of power batteries, reducing cold-start power loss
• Ultra-thin form factor saves internal package volume and weight compared with conventional insulation
• Thermal resistance equivalent to 8–10× conventional thermal insulation materials
• Porous core reduces solid conductive heat flow
• High vacuum minimizes convective heat transfer within the panel
• Composite reflective film reduces radiative heat transfer to enhance overall insulation

Applications & integration

• Primary applications: lithium-ion battery modules and packs for EVs, ESS, new energy power systems
• Integration tips: cut-to-size delivery, compatible with adhesive bonding and lamination processes; consider edge sealing and mechanical support in pack design
• Handling & storage: avoid puncture/impact, store in dry ambient conditions within recommended temperature range to preserve vacuum performance
