Pre-Oxidized Fiber Aerogel Sheets Block Thermal Runaway for Sunwoda

In July 2022, Sunwoda Electric Vehicle Battery in Shenzhen, Guangdong applied 1mm and 2mm aerogel cell insulation sheets for battery cell-to-cell thermal protection. These sheets use pre-oxidized fiber as the base material, sealed with flame-retardant PET film and hot-pressed edges for enhanced durability. The high-performance aerogel barriers effectively delay or block the spread of single cell thermal runaway to the entire battery system, featuring reliable flame retardancy and structural stability. This tailored solution elevates battery pack safety, meeting strict industrial standards for electric vehicle power battery safety and reliability.
