Low Dew Point Rooms for Lithium Batteries — Humiscope

Ultra Low Dew Point, Lithium Battery Rooms

“Li-S Energy enjoyed working alongside the Humiscope team. It was clear from the start they 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.

~Dr Lee Finniear, CEO, Li-S Energy (Lithium Battery Manufacturer)- Read Case Study

Lithium Battery Manufacturing

Lithium-ion, lithium iron phosphate, graphene and solid state are very sensitive to moisture with production spaces requiring an ultra low dew point, dry, stable environment with less than one percent humidity.

On top of the safety concerns, ultra-low dew point air supply is necessary to maximise product yield, product quality, energy efficiency, product life and storage capacity. 

It is a technically complex process.   For example, processing the lithium electrodes requires very low humidity levels – typically below 1% relative humidity (RH) and -35 or -55 dew point along with needing to be a low particulate environment.

“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 Batteries

Due to the chemical sensitivity to moisture of high energy batteries, specially designed ultra-low humidity, ultra-dry rooms are required to both test and manufacture lithium batteries.

When lithium metal and water mix, the reaction is exothermic (generates heat) and transforms into hydroxide and hydrogen which can lead to burning or even explosion.

ultra Low humidity and ultra low dew point dry rooms

In order to control humidity in lithium battery processing, hermetically sealed low dew point dry rooms were developed that allowed manufacturing to take place in extreme dryness, with very low humidity and provided particle filtration for cleanliness.

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”.
— Bob Galyen, global advisor in lithium technology

To avoid humidity and moisture issues, ultra-dry rooms using dehumidification technology is the ideal solution.  It is in fact an essential part of the manufacturing process.  It means turning your production room into an ultra-low dew point, ultra low humidity dry room where the ventilation is being mixed with return air and treated by the dehumidifier so that both temperature and humidity is controlled by the same unit.
