What are the common technologies for humidity control in lithium battery drying rooms?

Commonly used technologies for humidity control in lithium battery drying rooms include the following:

Dehumidifier: A dehumidifier is a common humidity control device that lowers indoor humidity by removing moisture from the air. It can automatically adjust its operation based on the set humidity level and maintain the humidity within an appropriate range.

Desiccant: A desiccant is a chemical substance that absorbs moisture from the air. Common desiccants include silica gel and activated carbon. Placing desiccants in a dry room can effectively reduce humidity.

Condensation Dehumidification: Condensation dehumidification is a method of humidity control that utilizes the principle of refrigeration. By lowering the air temperature, the moisture in the air condenses into liquid water, which is then discharged from the dry room, achieving the dehumidification effect.

Humidity Sensor and Control System: A humidity sensor can monitor the humidity level in the dry room in real-time and provide feedback to the control system. The control system automatically adjusts the operation of the dehumidification equipment based on the set humidity range to maintain the humidity within the appropriate range.

Air Circulation System: The air circulation system circulates the air, expelling humid air from the dry room and introducing dry fresh air. This effectively reduces indoor humidity and maintains air circulation.

It is necessary to select suitable humidity control techniques based on specific circumstances, taking into account factors such as production process requirements, equipment costs, and energy consumption. Additionally, regular inspection and maintenance of humidity control equipment are important measures to ensure its proper operation.
