Pressure Controlled Battery Calendering Machine with Heating
- Precision Electrode Rolling Solution for Lithium Battery Research
Model: MR-DG300T
The Pressure Controlled Battery Calendering Machine with Heating is a high-precision rolling press designed for compacting lithium-ion and sodium-ion battery electrodes. With integrated temperature-controlled heating rollers and precise pressure adjustment, this machine is ideal for both wet-coated and dry electrode processing.
It delivers consistent and uniform pressure, enhancing the density, flatness, and surface quality of electrode sheets. Heating functions allow better binder activation and material bonding, which are critical in advanced R&D and pilot-scale applications such as dry electrode, solid-state, and high-energy battery development.
Key Features
1. Pressure Control System: Real-time pressure monitoring and adjustable pressing force ensure stable and repeatable calendering results.
2. Heating Rollers: Temperature-adjustable rollers (up to 150°C) improve binder activation and electrode surface bonding.
3. High-Precision Roller Gap Adjustment: Supports fine-tuning of electrode thickness with micron-level accuracy.
4. Durable Roller Design: Hardened and mirror-polished rollers for uniform pressure distribution and long-term reliability.
5. User-Friendly Operation: Touchscreen control (or button panel optional) with digital display of pressure, temperature, and roller gap.
6. Safety Features: Emergency stop, overheat protection, and shielding to ensure safe operation.
Applications
* Lithium-ion, sodium-ion battery electrode preparation
* Dry electrode & solid-state battery research
* Electrode densification and surface conditioning
* Suitable for pouch cell, cylindrical cell, and prismatic cell R&D lines
