Accurate moisture and concentration measurements
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.
Vaisala’s measurement solutions help manufacturers to produce more high-quality products in a more sustainable and cost-effective way, and bring down costs in energy-intensive operations, such as drying and dry room operations.
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.
Measure accurately and real-time temperature (T), dew point (Td), relative humidity (RH), and liquid concentrations (nD), in midstream operations, and protect lithium from reacting with humidity and transforming into lithium hydroxide and hydrogen. In downstream operations, monitor temperature and relative humidity seamlessly.
A challenging production environment demands a water vapor detection instrument with reliable performance and 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.
Gloveboxes 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 glovebox combined with the probe’s chemical tolerance and fast reaction time enables extremely fast sequence control.
