EV battery manufacturing cooling system

TL;DR: The exponential growth of the electric vehicle market demands flawless lithium battery separators. Achieving this requires extremely stable cooling during the film stretching and quenching processes. High-precision chillers prevent thermal deformation, ensuring uniform thickness and significantly improving the yield and safety of high-energy-density batteries. Content: The global transition towards electric vehicles (EVs) and renewable energy storage has placed unprecedented demands on the battery supply chain. At the heart of battery safety and performance is the lithium battery separator—a microporous membrane that prevents short circuits while allowing ionic transport. In the highly complex wet manufacturing process of these separators, temperature control is not just a sec...
