Description
Electrode calendering is a critical process in lithium-ion battery manufacturing that involves compacting coated and dried electrode sheets using roller presses. This process enhances the adhesion between active materials and current collectors, increases cell energy density, and improves overall battery performance.
Product Overview
This machine is designed for laboratory-scale processing of battery materials, featuring adjustable rolling thickness and simple operation. It is particularly suitable for thinning and densifying lithium battery electrode sheets in clean energy applications.
Key Features
- Hydraulic system: Automatically controls rolling pressure for consistent results.
- Premium rollers: Made from imported cold-rolled steel with heat-treated, chrome-plated surfaces for high internal/external hardness and wear resistance.
- Patented hydraulic balancing mechanism: Ensures stable pressure and uniform rolling (both transverse and longitudinal).
- Monolithic gantry frame: CNC-machined for high precision and stability.
- Optional winding/unwinding modules.
