For lithium battery manufacturers, proper moisture control is a critical variable for safety, yield, and cost. And while desiccant dehumidification is the proven way to reach ultra‑low dew points, performance and operating expense also depend on how you design the dry room, and which dehumidifier you select. For success, manufacturers and labs require a tight, well‑engineered dry room envelope plus a high‑performance desiccant system tuned to your loads.
