Hello! Here are some suggestions based on our company's accumulated experience in the lithium battery industry over a long period of time. Please advise us.
Application of Dew Point Meter in the Battery Industry
1： Why is dew point measured in the production of lithium batteries?
1. By measuring the dew point value, it can be determined whether the equipment is operating normally;
2. Battery materials need to be kept dry to a certain extent;
3. By understanding the dew point value of the glove box, product quality can be ensured;
4. Detecting and controlling humidity (dew point) during the production process can improve product qualification rate, reduce costs, increase output, and improve quality.
5. Lithium metal has excellent oxidizing properties towards water, gas, and oxygen. Therefore, the basic conditions and equipment for producing lithium-ion polymer batteries are essential Very strict, no
Prior testing or assembly must be conducted in an environment with extremely low concentrations of water and oxygen.
2： What are the problems encountered during dew point measurement in the production process?
1. Service life: When producing lithium batteries, during the process of injecting electrolyte, the electrolyte contains LiPF 6, which will produce a substance similar to hydrogen fluoride (HF) when exposed to moisture
Gas, this corrosive gas will cause corrosion and drift in accuracy of most dew point meter probes, greatly reducing the lifespan of the dew point meter.
2. Accuracy: In battery production, the change in dew point humidity value of the manual control box or drying room depends on whether the drying equipment is operating normally
The material and material retrieval process, the number of workers in the drying room, and the frequency of entry and exit are related, because some dew point meters have insufficient sensitivity, which affects the quality control
Reason brings a lot of trouble.
3. Maintenance: The installation position of the dew point meter in the manual control box and drying room is very important, as corrosive gases generated during the production of lithium batteries can directly affect the dew point
The lifespan and accuracy of the point instrument.
3： Handling method:
Measuring and controlling humidity (dew point) is a crucial parameter in the production process of lithium batteries. Dew point meters have different working principles and safety requirements
The installation method is very important, so how to choose and install a dew point meter is also a key issue. Our company specializes in engineering when selling dew point meters
Teachers will communicate with customers on site to understand and help users choose the installation location, which can not only reflect the dew point accurately and quickly, but also ensure the dew point
The lifespan of the point instrument.
4： Product recommendation and introduction:
VAISALAL's dew point meter products have shown performance in humidity measurement in the battery industry's manual control boxes and drying rooms. In response to this situation, our company has
Do not apply corresponding anti-corrosion treatment to several dew points used in the battery industry.
Dew point meters in the lithium battery industry include DM70 (handheld)
）Wait, the dew point probe of this product itself has a self heating function,
Instantly heated to 160-180 ℃ to evaporate the moisture in the probe, LiPF 6 will not corrode the probe without encountering moisture during the heating process
In addition, the dew point meter also has a zero point automatic correction function, which can ensure the accuracy of dew point measurement. Our company has taken corresponding measures to address the corrosion issue on the probe
Add anti-corrosion protection touch on the surface of the head. Greatly improved the lifespan of dew point meter probes.
