Lithium Battery Electrode Drying Kiln Exhaust Heat & Moisture Recovery

Project Background

Before calendering, power-battery electrodes must be treated in a drying kiln, with exhaust air being highly humid and hot.

Challenges

Drying energy is a large share of line power use, and high ambient humidity hurts electrode quality.

Solution

Desiccant Rotor DehumidifierSupplies low-dew-point dry air, combined withRotary Heat Exchangerrecovering and reusing exhaust energy.

Results

Drying-kiln energy reduced by 15%, with the dew point stably controlled below -20℃.
