Ensuring Quality and Efficiency in Battery Production
Humidity and temperature sensors play a crucial role in various aspects of lithium battery manufacturing, ensuring product quality, enhancing production efficiency, and extending battery lifespan. These sensors are employed throughout the manufacturing process, from material preparation to battery assembly and storage.
In midstream operations, HENGKO focuses on producing high-quality products more sustainably and cost-effectively. We strive to reduce expenses in energy-intensive tasks, such as drying and dry room operations, which consume approximately 40% of the total energy used during manufacturing. It is vital to protect lithium from reacting with humidity, which can cause it to transform into lithium hydroxide and hydrogen.
Accurate and Real-Time Measurement Capabilities:
In downstream operations, monitoring temperature and relative humidity seamlessly is essential. Our technology also enables the accurate measurement of aggressive chemicals in upstream processes.
HENGKO offers world-class measurements with technologically advanced products, particularly suited for ultra-dry conditions and for critical processes in filling and sealing operations.
Stringent humidity and temperature control is essential during lithium battery material preparation to maintain material purity and consistency. For instance, in positive electrode material preparation, humidity must be within a specific range to prevent material moisture absorption or loss. Humidity and temperature sensors continuously monitor and regulate the production workshop’s environment, ensuring that process conditions meet the required specifications.
Numerous processes in lithium battery production have specific humidity and temperature requirements. For example, in the electrode coating process, both temperature and humidity need to be controlled to achieve uniform coating. Humidity and temperature sensors monitor and control these parameters, improving production efficiency and reducing scrap rates.
Lithium battery performance and lifespan are influenced by ambient humidity and temperature. High temperatures accelerate battery self-discharge, while low temperatures reduce battery capacity. Humidity and temperature sensors monitor these parameters during battery usage and enable measures to prevent overheating or overcooling, extending battery lifespan.
Positive Electrode Material Preparation: Humidity in this process is controlled between 30%RH and 60%RH, and temperature between 20°C and 30°C. Humidity and temperature sensors monitor and regulate the workshop environment to meet these specifications.
Electrode Coating: During electrode coating, temperature is maintained between 25°C and 30°C, and humidity between 50%RH and 70%RH. Humidity and temperature sensors monitor and control these parameters in the coating workshop, ensuring uniform coating.
Battery Assembly: Temperature during battery assembly is controlled between 20°C and 25°C, and humidity between 40%RH and 60%RH. Humidity and temperature sensors monitor and regulate these parameters in the assembly workshop to prevent battery moisture ingress.
Battery Storage: During battery storage, temperature is maintained between 10°C and 20°C, and humidity between 30%RH and 60%RH. Humidity and temperature sensors monitor and regulate these parameters in the storage warehouse to prevent battery performance degradation.
When using humidity and temperature sensors in lithium battery manufacturing, consider the following:
Select appropriate sensor models: Ensure the measuring range and accuracy meet the requirements.
Install sensors in well-ventilated areas: Avoid heat and pollution sources.
Regularly calibrate and maintain sensors: Ensure measurement accuracy.
Humidity and temperature sensors are indispensable instruments in lithium battery manufacturing, playing a vital role in ensuring battery material quality, enhancing production efficiency, and extending battery lifespan. As lithium battery manufacturing technology advances, humidity and temperature sensors will find even wider applications.
Glove boxes are a crucial component in battery manufacturing, offering a controlled, sealed, and inert atmosphere that maintains low levels of moisture and oxygen. This environment is essential for protecting lithium, electrodes, and other sensitive materials from moisture and oxygen, which can lead to degradation.
HENGKO’s compact and integrable measurement probes help maintain desired low humidity levels and keep humidity under strict control during glove box operations. This ensures the electrolytes are protected from decomposing, while also maintaining the quality, safety, and performance of battery components.
The probes’ direct installation in the glove box, along with their chemical tolerance and rapid reaction time, allows for extremely fast sequence control, enhancing operational efficiency.
To maintain the desired humidity and temperature within the safety glove box, the following strategies are commonly employed:
Using Humidity and Temperature Sensors: These sensors continuously monitor the glove box’s internal humidity and temperature.
Utilizing Air Conditioners or Dehumidifiers: Air conditioners regulate temperature, while dehumidifiers control humidity.
Regular Inspection and Maintenance: Regularly inspect and maintain humidity and temperature sensors, air conditioners, and dehumidifiers to ensure proper operation.
Material Preparation: Maintain glove box temperature between 20°C and 30°C and humidity between 30%RH and 60%RH during material preparation.
Electrode Coating: Control glove box temperature between 25°C and 30°C and humidity between 50%RH and 70%RH during electrode coatin.
