Battery manufacturing Accurate moisture and liquid concentration measurements Contact us Lithium battery Glovebox WHY VAISALA NMP Lead acid battery Related content Products Industrial scale battery manufacturing is done in almost clean room type of environments, where ambient conditions are stable and under control, with ultra-low humidity environment maintained for safety, yield, and efficiency. This level of precision is essential as electrolytes are super sensitive to moisture and will start to decompose in too humid conditions, directly impacting the battery performance or even requiring reprocessing. Furthermore, the manufacturing process involves handling moisture-sensitive chemicals, which, if exposed to elevated moisture levels, can pose security risks. Strict process control, contamination prevention, and cleanliness are imperative throughout the manufacturing process.
