The Design and Build of a Low Dew Point, Ultra-Dry Room for Lithium Battery Production

Описание: 2024 UPDATE: Room is consistently maintaining -70° Dew Point. Making it the driest room in Australia. Client has stated:
“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.
~ Dr Lee Finniear, CEO, Li-S Energy

Humiscope are experts in dehumidification technology and controlling indoor environments. We have worked on several projects where ultra-low dew point and ultra-low humidity is required. Our most recent project was to design and build a lithium battery manufacturing and R&D room, for Li-S Energy.

See the project unfold - from initial 3d concepts through to a completed 220sqm Ultra-dry Room for the manufacture of Lithium Sulfur Batteries.

The Room and Current Conditions

• 0.1% Relative Humidity (RH) Dry Room
• 20 - 22ۥ° C Temperature
• -70° Dew Point
• Hermetically Sealed Wall System
• Sealed and Insulated Air Duct
• Chiller and Desiccant Dehumidification Unit

This dry room is one of the largest in Australia. It has a complex external infrastructure, including a large external chiller that works in tandem with a desiccant dehumidifier to dry the atmosphere. The dew point remains consistently below -50°C and the dry air is circulated into the dry room through a maze of sealed ducting and filtration systems.

Humiscope designed the desiccant dehumidifier to create the optimal dry environment where the dry air is circulated into the room through the ducting and filtration systems. The unit was manufactured in Europe by Humiscope’s long-time supplier, TFT Dry Air Solutions.

The room includes a sealed airlock that enables the production teams to enter and leave the dry room while preventing the external atmosphere from contaminating the facility.

The dry room’s purpose is to provide a safe and stable environment for the manufacture of lithium batteries. The dry atmosphere enables the automated anode production equipment and Li-S Energy's team to operate at full capacity without the restriction of inert gas enclosures or glove boxes.

This project could not have come to fruition without the amazing work of the Humiscope team, Ladan Bagherzadeh, our savvy lead mechanical engineer, Paula Andrea Gil, our highly talented draftsman and of course our fearless leader John Morgan.

Li-S Energy is working with lithium sulfur and lithium metal technology to deliver lighter batteries with more than twice the energy density and — with no heavy metals — offering a cleaner and greener alternative.

Lithium sulfur battery chemistry has been known to battery scientists for quite some time, but until now cells always failed too quickly — making them commercially unviable.

Li-S Energy is an ASX listed company created to solve this long-standing issue. They have successfully created a lightweight lithium sulfur battery with a cycle life approaching that of lithium ion.
