As the demand for electric vehicles (EVs) continues to surge, the spotlight on battery technology has never been brighter. Battery cell production, assembly, and the entire lifecycle of these energy storage devices play a pivotal role in shaping the future of sustainable transportation.
Efficient battery cell assembly is the foundation of high-performance energy storage solutions. One often overlooked factor is the significance of controlling humidity during the assembly process. Excessive moisture can adversely impact the performance, reliability, and lifespan of battery cells. That’s where dehumidifiers come into play as essential tools in ensuring optimal conditions and safeguarding battery quality.
The role of dehumidifiers in battery cell assembly
Dehumidifiers play a vital role in maintaining optimum conditions in battery dry rooms where battery cells are assembled. Battery cell assembly requires a controlled environment to ensure the longevity and reliability of the final product. Dehumidifiers are crucial for maintaining the necessary humidity levels during assembly. By removing excess moisture, these dry-air solutions prevent the formation of corrosion and the growth of contaminants, leading to improved performance, safety, and overall quality of the battery cells.
- Moisture control: By maintaining controlled humidity levels, dehumidifiers help prevent moisture absorption by battery materials, such as electrodes and electrolytes. This ensures consistent performance and extends the longevity of the battery cells.
- Contaminant mitigation: Dehumidifiers also help minimise the risk of contamination during assembly. By reducing airborne particulates, dust, and pollutants, they create a clean and controlled environment for precise cell production.

Cotes Ultradry Adsorption Dehumidifiers
Lithium-ion battery dry rooms use a lot of energy. Up to 43% of total energy consumption in the battery manufacturing process is used to keep the dry rooms super dry — that’s a relative humidity of below 1% and dew points ranging from -40°C to -120°C. Traditional dehumidifiers are criticised for their high dependency on electricity and gas with ineffective drying processes at high temperatures.
Cotes Ultradry adsorption dehumidifiers are the world’s most sustainable and energy-efficient solution for battery dry rooms. Cotes Ultradry ensures high energy efficiency, reduces the total cost of ownership, and maintains optimum humidity control with low dewpoint, enabling the best battery performance and a safe working environment.
With our innovative patented Exergic Technology, the Cotes Ultradry solution maximises energy savings by utilizing three rotors and hot water at 80-90°C obtained from sustainable energy sources such as waste heat, biomass, solar thermal panels, CO2 heat pumps, and electricity from renewable energy from wind, hydro, or solar power.
Cotes Exergic Technology can give you a competitive advantage by saving up to 66% on your dry room energy bills and reducing up to 95% of dry room CO2 emissions due to the efficient ultradry system that operates safely at extremely low dew points, as low as -120°C.
