Control Equipment’s Product Advantages

________________

Focused solutions for all aspects of
Lithium-ion Battery Production

Control Equipment Pty Ltd has developed gas detection solutions for all production processes of lithium-ion battery manufacturing, which are typically high temperature environments. By utilising direct insertion and heat resistant gas detection technology, accurate gas monitoring can be achieved in high temperature conditions often required by coating and drying processes.

Gas Monitoring for Coating and Drying

 

POINT 01

Measuring vaporised combustible gas at high temperature
High heat resistant duct-mounted monitors
withstand operating temperatures up to 200℃,
ideal for coating and drying process.

 

 

 

POINT 02

 

Accurately measure gas concentrations at the duct center point
Direct insertion design (250 mm) enables diffusion monitoring at the center of the duct

 

 

 

POINT 03

 

ATEX/IECEx/UL certifications/approvals
Explosion-proof design

 

 

 

POINT 04
Resistance against silicon
Low sensitivity degradation, excellent safety

 

 

 

Silicon material covers the catalyst surface of the sensor and then it reduces the sensor sensitivity.

 

In volatile organic silicone atmospheres, catalytic poisoning (SiO2 film formation) due to chemical reactions degrades the sensitivity of catalytic combustion method sensor.
In volatile organic silicone atmospheres, catalytic poisoning (SiO2 film formation) due to chemical reactions degrades the sensitivity of catalytic combustion method sensor.
Silicone poisoned sensors cannot provide correct readings because the response to NMP is degraded.Therefore, we have taken measures to reduce the sensitivity degradation in the sensor.
*In general, Ethanol often used as the calibration gas which is relatively easy to obtain and handle. However, since ethanol has a small molecular weight, “silicon poisoned deteriorated sensor” will react. Control Equipment Pty Ltd succeeded to suppress the deterioration in order to display the accurate NMP gas concentration with ethanol calibrated sensor.

Importance of Gas Detection

Why detect for gases in lithium-ion battery production?

During the production of lithium-ion batteries, processes use or generate gases, which can be combustible or toxic. Exceeding safe concentrations of these gases can put your people and equipment at risk. Protect your people and property by installing gas detection designed for lithium-ion manufacturing applications.

Electrode Manufacturing

Drying Process

In the production of electrodes for lithium-ion batteries, NMP is used as a solvent. NMP will only vaporize at high temperatures during the drying processes. As concentrations of NMP build up, the risk of explosion increases. An ideal location to detect NMP is within the exhaust duct. By utilising direct insertion design into the exhaust duct, detection of NMP will be at the center of the duct and able to withstand high temperatures and high concentrations.

Cell Assembly

Electrolyte filling process

A variety of solvents are mixed in electrolytes, such as DMC, EMC, and DEC.These have the potential to explode if vaporized, so gas detectors are required.

Testing Process

Every Lithium-ion battery is required to pass a test without emitting gas in a harsh environment. Combustible gas and toxic gas may be generated from the battery in the evaluation test process. Gas concentration monitoring is essential to prevent ignition and poisoning accidents during the testing process. When the gas detector detects the target gas, it is necessary to take outside air from the intake / exhaust damper to reduce the gas concentration in the test equipment.
