Battery manufacturing

Industrial scale battery manufacturing is done in almost clean room type of environments, where ambient conditions are stable and under control, with ultra-low humidity environment maintained for safety, yield, and efficiency. This level of precision is essential as electrolytes are super sensitive to moisture and will start to decompose in too humid conditions, directly impacting the battery performance or even requiring reprocessing. Furthermore, the manufacturing process involves handling moisture-sensitive chemicals, which, if exposed to elevated moisture levels, can pose security risks. 

Strict process control, contamination prevention, and cleanliness are imperative throughout the manufacturing process.

Upstream, midstream, downstream

In midstream operations, produce more high-quality products more sustainably and cost-effectively, and bring down costs in energy-intensive operations, such as drying and dry room operations, which take about 40 % of total energy usage during manufacturing. Protect lithium from reacting with humidity and transforming into lithium hydroxide and hydrogen.  

Measure accurately and in real-time: 

  • temperature (T)
  • dew point (Td)
  • relative humidity (RH) 
  • liquid concentrations (nD) 


Monitor temperature and relative humidity seamlessly in downstream operations. 

Measure aggressive chemicals accurately in upstream processes. 

The world-class measurements with technologically best-suited products especially for ultra-dry conditions and for critical filling and sealing operations are only available from Vaisala.  

The benefits of a rapidly reacting probe in a battery manufacturing dry room

Drying is one of the costliest operations in a battery manufacturing dry room. Drying is also a delicate act as overdrying is expensive and underdrying is dangerous. 

Fight the silent, but deadly virus of humidity efficiently and precisely. 

Learn why it all can fail if a dew point probe in a dryer reacts slowly.  

Reliability and simplicity in your critical battery manufacturing measurement points

Make smart choices, and reduce your workload and uncertainty in battery manufacturing by selecting accurate and reliable measurement instruments. 

Versatile measurement solutions with Indigo

Detect water vapor with a measurement instrument that holds reliable performance in challenging production environments. Indigo transmitters also have strong resistance to process byproducts that may be present in the atmosphere. 

Vaisala offers a chemically resistant polymer dew point sensor that is actively manipulated to achieve long-term reliability with very little measurement drift. Calibrated devices using this sensor are available as low-cost transmitters or fully configurable field instruments. 

Our trusted products tolerate the most extreme conditions and aggressive chemicals.

Secure glove box operations

Glove boxes are an essential tool in battery manufacturing providing a controlled, sealed, and inert atmosphere maintaining low levels of moisture and oxygen, and protecting the lithium, electrode, and other materials from reacting with and degrading from moisture or oxygen. 

Maintain desired low humidity levels and keep humidity in strict control during glovebox operations and electrolytes safe from decomposing, while ensuring quality, safety, and performance of battery components with Vaisala’s small-in-size and integrable measurement probes. 

Direct installation in the glove box combined with the probe’s chemical tolerance and fast reaction time enables extremely fast sequence control.

Dew Point Transmitter DMT152 for very dry environments



Save energy in all dryer operations of a dry room. Manage dryer precisely, and benefit from the probe’s rapid response time for immediate dryer adjustments. 


Monitor dry room conditions with Vaisala Indigo products and ensure consistent and on-target operations for both standard and specialized conditions. High-performance Vaisala Indigo products are already suitable for the dry requirements of the future.


Vaisala products are good with everything as the measurement probes are designed to be in the most demanding environments.


Gather data with Indigo products, equip dry room with local screens, and feed data to the supervisory control and data acquisition system (SCADA) for immediate adjustments and safe processing. 


Versatile measurement solutions, including measurement range, temperature, sampling solutions, support for various digital outputs, and probes with chemical tolerance. 

Ecosystem execution in design enables mixing and matching probes meeting specific needs.
