Ultra-Low Dew Point Dry Rooms for Lithium Battery Manufacturing
Lithium-ion, lithium iron phosphate, graphene and solid-state batteries are highly sensitive to moisture. Even trace levels of humidity during production can damage electrodes, reduce capacity, shorten cycle life and create serious safety risks. That’s why lithium battery manufacturing and testing requires ultra-low dew point, ultra-dry rooms with less than one percent relative humidity.
Humiscope designs and builds low dew point dry rooms that give you a stable, tightly controlled environment for every stage of cell fabrication – from mixing and coating through to assembly and formation.
Ultra-low dew point air supply is essential to maximise product yield, energy efficiency, product quality, cell performance, and long-term storage safety.
Lithium Battery Manufacturing in Ultra-Dry Conditions
In lithium battery processing, humidity control is not optional – it is a critical process parameter. Moisture ingress into the cell can react with lithium metal and electrolyte, generating gas, heat and unwanted by-products that compromise safety and performance.
Humiscope low dew point rooms are engineered specifically for:
Li-ion, Li-S and solid-state cell manufacturing
Pouch, cylindrical and prismatic cells
Pilot lines, R&D facilities and full-scale gigafactories
By integrating dehumidification, filtration and airflow design, we create a uniform, ultra-low moisture environment that protects your people, process and product.

Proven Results for Lithium Battery Manufacturers
Humiscope has designed and delivered low dew point, ultra-dry rooms for leading lithium battery manufacturers in Australia and internationally. Our clients rely on us to translate stringent humidity requirements into practical, buildable solutions that work day-to-day on the production floor.
““It was clear from the start they (Humiscope) had a thorough technical understanding of the requirements necessary to design and build a low dew point environment. Not only that, they listened to our requirements, provided realistic timeframes, and delivered on their promise.”
Watch how Humiscope designed and built a low dew point, ultra-dry room for lithium battery production.
Engineering Low Dew Point, Ultra-Dry Rooms
Designing a low dew point room for lithium electrodes is technically complex. Lithium processing typically requires:
Relative humidity below 1%
Dew point temperatures of –35°C to –55°C or lower
Low particulate environment with high-efficiency filtration
Humiscope’s engineering team models airflow, moisture load and heat gain to size the dehumidifiers, chillers and air handling equipment correctly from the outset. The result is a room that consistently meets your dew point targets – even under full production load.
““Now fully operational, the ultra-dry room is exceeding performance expectations - enabling us to have more staff in the cell fabrication area at the same time should we need them, while maintaining the low humidity required for lithium.””
Low Dew Point Rooms for Lithium Battery Safety
Due to the chemical sensitivity of high-energy batteries, specially designed ultra-low humidity, ultra-dry rooms are required to safely test and manufacture lithium batteries.
When lithium metal and water mix, the reaction is exothermic and generates heat, hydrogen and hydroxide. In a production environment this can lead to venting, burning or, in extreme cases, explosion.
Humiscope low dew point rooms help you:
Reduce the risk of moisture-related safety incidents
Protect staff working in cell fabrication and testing areas
Meet regulatory and insurance expectations for lithium processing

Ultra-Low Humidity and Low Dew Point Dry Room Design
In order to control humidity in lithium battery processing, hermetically sealed low dew point dry rooms are developed so that manufacturing can take place in extremely dry conditions with very low humidity and clean, filtered air.
Key design considerations include:
Airlock and transfer systems that minimise moisture ingress
Dehumidification systems sized for process loads, people and equipment
Zoned environments for different process steps and humidity set points
Filtration and airflow patterns that control particles as well as moisture
“Successful manufacturing of lithium sulfur cells has eluded scientists for many decades, so to see the progress Li-S has made, not just on the chemistry side, but also in the engineering of this masterfully designed facility, in just a few short years really impresses me”. ”
Protecting Lithium Battery Materials and Components
Ready to Protect Your Stored Materials?
Lithium cells, powders, electrolytes and components are often stored for extended periods before use. Without humidity control, storage environments can quickly undo the quality gains made at the production line.

Low Dew Point Room Resources
To avoid humidity and moisture issues, ultra-dry rooms using dehumidification technology are the ideal solution for lithium battery manufacturing. They turn your production area into an ultra-low dew point, ultra-low humidity dry room where ventilation and return air are treated by the dehumidifier so both temperature and humidity are controlled by the same system.
