Lithium reacts with moisture to form lithium hydroxide and hydrogen — compromising battery quality, performance, and safety. For this reason, lithium battery production requires some of the most demanding dry room conditions of any manufacturing environment: relative humidity below 1%, maintained continuously and reliably at scale. DST desiccant dehumidifiers are trusted by the world’s leading battery manufacturers — including Tesla, CATL, BYD, LG Chem, VARTA and Panasonic — to maintain these conditions throughout every stage of battery production.
Lithium-ion and lithium-polymer battery production is uniquely sensitive to moisture. Even trace amounts of water vapour cause chemical reactions that degrade active materials, reduce energy density, shorten battery life, and in extreme cases create safety risks. Production environments for electrode coating, cell assembly, and electrolyte filling must maintain relative humidity well below 1% — and in some processes, dew points as low as -40°C or below.
DST desiccant systems transform production rooms into fully controlled dry rooms, maintaining these extreme low-humidity conditions continuously regardless of outdoor climate, occupancy, or production throughput. Our systems are designed for the high airflow volumes, tight dew point tolerances, and energy efficiency demands of modern gigafactory-scale operations.
See how DST desiccant dehumidification systems are integrated into lithium battery production facilities — from R&D laboratories and pilot lines to full-scale gigafactory dry rooms. Our systems maintain precise dew point control across electrode production, cell assembly, and electrolyte handling areas.
DST supplies dry room dehumidification across multiple Tesla gigafactory sites — covering cathode production, anode mixing, cell assembly, and unloading areas at Brandenburg, Austin TX, and Fremont CA.
Dry room dehumidification for CATL — the world’s largest lithium battery manufacturer — maintaining the precise low-humidity conditions required for high-volume cell production.
Two separate DST installation phases for BYD’s battery production facilities, providing dry room dehumidification for one of the world’s largest EV and battery manufacturers.
DST has been supplying dry room dehumidification for lithium battery production since the early 2000s — growing alongside the industry from research laboratories to gigafactory-scale operations. Our systems are configured to meet the specific dew point, airflow, and energy requirements of each production process, from pilot lines to full-scale manufacturing.
