High Precision Roll To Roll Integrated Calendaring & Slitting Machine for Lithium Ion Batteries
PRODUCT PARAMETERS
Description
Integrated Calendaring and Slitting Machine for Lithium Battery Electrodes | 700mm Width | 400T Pressure | CE Certified
Product Overview
The Gelon Integrated Calendaring and Slitting Machine is a state-of-the-art, high-precision system engineered to combine two critical electrode production processes – calendaring and slitting – into a single, efficient roll-to-roll operation. We developed this advanced machine to streamline lithium-ion battery manufacturing by eliminating the need for separate equipment, reducing handling, and improving overall production efficiency.
This integrated machine first continuously calenders the positive or negative electrodes after coating using a powerful hydraulic roller system, achieving the precise thickness required by your process. Immediately afterward, it slits the calendared electrode into 2 to 4 strips of the desired width and rewinds them with precise alignment – all in one continuous pass.
With an effective rolling width of 700mm, 800×800mm rollers, and a massive 400-ton maximum working pressure, this machine delivers industrial-scale performance. Furthermore, it achieves exceptional precision with calendaring accuracy ≤ ±2μm, width cutting accuracy ≤ ±0.3mm, and correction accuracy ≤ 0.1mm. The result is a high-quality electrode ready for the next stage of battery assembly.

Why Choose an Integrated Calendaring and Slitting Machine?
Traditional electrode production requires separate calendaring and slitting machines, which means additional floor space, extra material handling, and potential alignment issues between processes. Our integrated calendaring and slitting machine solves these challenges by:
- Combining two processes – calendaring and slitting in one continuous line
- Reducing labor and handling – fewer transfers between machines
- Saving valuable floor space – one machine instead of two
- Improving alignment accuracy – no re-alignment needed between steps
- Increasing throughput – continuous operation from coated roll to slit rolls
- Ensuring consistent quality – integrated control of both processes
Key Design Features
1. High-Pressure Hydraulic Calendaring System
We equipped this integrated machine with a powerful hydraulic roller press that delivers up to 400 tons of working pressure. The 800×800mm rollers with hardness of HRC66-68 ensure uniform compression across the entire 700mm effective rolling width.
2. Exceptional Calendaring Precision
The system achieves ≤ ±2μm calendaring accuracy, ensuring consistent electrode density and thickness – critical factors for battery performance and cycle life.
3. Integrated Precision Slitting
Immediately after calendaring, the electrode passes to the integrated slitting station where it is cut into 2 to 4 strips with width cutting accuracy ≤ ±0.3mm. The cutting burrs are strictly controlled:
- Foil burrs: ≤10μm
- Vertical direction of coating area: ≤7μm
4. High-Accuracy Correction System
The machine features a correction accuracy of ≤ 0.1mm, ensuring the electrode remains perfectly aligned throughout both calendaring and slitting processes.
5. Wide Electrode Compatibility
- Incoming electrode width: 50 – 800mm
- Flexible to handle various electrode formats
- Suitable for both cathode and anode electrodes
6. Robust Industrial Construction
- Roll diameter: Φ800 × 800mm (customizable)
- Roll hardness: HRC66-68 for long service life
- Power: 120KW
- Voltage and frequency: AC380V / 50Hz
7. Fully Automatic Operation
The roll-to-roll design ensures continuous, uninterrupted production with minimal operator intervention.

How the Integrated Calendaring and Slitting Machine Works
Step 1: Electrode Feeding
The coated electrode roll (cathode or anode) is loaded onto the unwinding station. The incoming electrode width can range from 50mm to 800mm.
Step 2: Precision Calendaring
The electrode passes through the 800×800mm hydraulic rollers under up to 400 tons of pressure. The rollers, with hardness HRC66-68, compress the coating to the target density with ≤ ±2μm accuracy.
Step 3: Continuous Slitting
Immediately after calendaring, the electrode enters the integrated slitting station. Here, it is precisely cut into 2 to 4 strips with width cutting accuracy ≤ ±0.3mm. The cutting burrs are strictly controlled to ≤10μm on foil and ≤7μm on coating vertical direction.
Step 4: Alignment and Rewinding
Throughout the process, the correction system maintains alignment with ≤0.1mm accuracy. The slit strips are rewound onto separate rolls, perfectly aligned and ready for the next production stage.
Step 5: Quality Assurance
All parameters – pressure, thickness, slit width, alignment – are continuously monitored to ensure consistent, high-quality output.
