Furthermore, dry rooms for lithium batteries need a greater humidity control of around minus 50.0°Cdp at the point of return. The battery chemistry of the next generation of lithium batteries may have even tighter requirements. The specification could reach minus 80.0°Cdp at the point of supply into critical areas, such as Electrolyte Fill.
These cleanrooms are engineered to maintain extremely low levels of humidity, often below 1% RH (relative humidity), to ensure the safe and precise handling of lithium-ion battery components. The absence of moisture is crucial as it prevents the risk of thermal runaway or explosions that can occur when moisture interacts with lithium-ion materials.
Battery dry room cleanrooms are equipped with specialized equipment and materials to maintain these dry conditions, allowing for the production of high-performance, safe, and reliable batteries used in a wide range of applications, from consumer electronics to electric vehicles and renewable energy storage.
The market for lithium-ion battery manufacturing is growing rapidly. The global lithium-ion battery market is about to be $44.5 billion in 2022 and will reach $135.1 billion by 2031.
