Battery Coating & Drying Solutions by Yueyu
What Drives the Need for High-Performance Battery Coatings?
Battery electrode coating is a core process that determines energy density, safety, and lifespan, involving precise slurry coating and drying. With the explosive growth of new energy vehicles, the global lithium battery equipment market surpassed 100 billion USD in 2023, with coating equipment accounting for 30%. Consequently, demand for high-stability centrifugal fans has surged worldwide.
Yueyu Centrifugal Fans Meet Diverse Needs
● Coater Air Supply System:
Yueyu’s YYCBA centrifugal fans provide stable airflow for slit-extrusion coating heads, ensuring slurry coating thickness tolerances within ±1.5 μm. Constructed from 316 stainless steel, they resist NMP solvent corrosion.
● Drying Oven Heat Circulation:
Multi-layer ovens maintain a uniform temperature field of 60–120 °C with airflow fluctuations within ±5%. Yueyu YYCBA fans, designed for high airflow, reduce drying time by 30% and minimize the risk of film defects.
● VOC Emission Treatment:
Yueyu YYDE centrifugal fans recover acetone/NMP-laden exhaust gases. Explosion-proof models (e.g., EX-certified) can be integrated with RTO incineration systems for optimized VOC handling.
Product Core Advantages
✓ Corrosion-Resistant Breakthrough:
Featuring 316L stainless steel impellers with PPSC anti-stick coating, the fan lifespan is three times longer than carbon steel models, reducing maintenance costs by 40%.
✓ Precise Fluid Control:
Static pressure accuracy of ±50 Pa ensures clean coating edges without overflow, while variable frequency drives save 25–60% energy.
✓ Modular Design:
Detachable components reduce maintenance time from 4 hours to just 30 minutes.
