Ultra Dry Rooms for Lithium Battery Manufacture
The need for and use of lithium batteries has increased dramatically over the past few years and an ultra low dew point, ultra dry environment is required for its manufacture.
Why Lithium Batteries?
Lithium-ion batteries are lighter than alkaline batteries and offer high operation voltage and high-power storage, therefore widely used as a power source for portable devices such as mobile phones, laptops, and digital cameras.
They can operate unhindered in extreme low temperatures, so ideal for outdoor applications. They are also energy efficient and are being used to power hybrid and electric cars.
Lithium-ion Batteries
Needless to say, the research and production of lithium batteries is more popular and more important than ever before.
Why Ultra Dry Rooms?
Due to the chemical sensitivity to moisture of high energy batteries, specially designed ultra-low humidity dry rooms are required to both test and manufacture lithium batteries.
In order to control humidity in lithium battery processing, hermetically sealed ultra dry rooms were developed that allowed manufacturing to take place in extreme dryness, with very low humidity and provided particle filtration for cleanliness.
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° C or -60° C dew point along with needing to be a low particulate environment.
Humiscope provided the complete ultra dry room solution for Australian corporation, Cap-XX for its manufacture of supercapacitors for global.

Desiccant dehumidifiers for ultra Dry Rooms
To avoid humidity and moisture issues, the optimal solution is to use dehumidification technology. 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, ultra dry room where the ventilation is being mixed with return air and treated by the dehumidifier. This allows both temperature and humidity is controlled by the same unit.
Issues of Uncontrolled Humidity in lithium battery manufacturing
Lithium reacts strongly with moisture. When lithium metal and water in the air mix, the reaction is exothermic (generates heat) and can lead to burning or even explosion. Moisture sealed inside the battery can react even after the battery is completed. Also, flammable solvents are often used in these rooms therefore an exhaust system is important to remove the solvent vapours.
Lithium + Moisture Don’t Mix
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. When lithium mixes with moisture it transforms into lithium hydroxide and hydrogen and product quality, performance, and durability can deteriorate significantly.
Humiscope Designs and Builds Low Dew Point, Ultra-Low Humidity Ultra Dry Rooms
Using the latest indoor climate control technology, we design your state-of-the-art dry room specific to the application and to fit the space or area in which it is needed. We install the room ready to operate (or can deliver ready to operate). We have also worked with pre-existing spaces, creating dry rooms in warehouses and factories.
We always offer ongoing support and maintenance if and when it is required.
