Product description
Product Name: Custom Battery Electrode Sheet Fabrication Service (R&D and Pilot Scale)
Service Summary
Our Custom Electrode Sheet Fabrication service offers researchers and manufacturers a critical outsourcing solution for creating high-precision, customized battery electrodes for Lithium-ion, Sodium-ion, Lithium-Sulfur, and Supercapacitor research. We transform your raw materials (active material, binder, conductive additive, solvent) into perfectly cast, dried, calendered (rolled), and slit electrode sheets, ready for immediate cell assembly.
This service eliminates the need for large capital investment in specialized equipment (like the Electrode Coating Device and Cold Rolling Mill) and ensures the highest level of quality and uniformity—the foundation for reliable, high-performance electrochemical testing.
Key Service Offerings
| Fabrication Step | Process Control and Customization | Critical Importance |
| Slurry Mixing | Precise control of solid content, viscosity, and particle dispersion time. | Ensures homogeneous distribution of active material and conductive additives, minimizing hot spots and optimizing conductivity. |
| Precision Coating | Coating Method: Doctor Blade, Slot-Die, or Comma coating (selected based on slurry rheology). | Achieves target coating thickness (e.g., $\pm 5 \mu m$) and areal mass loading ($\text{mg}/\text{cm}^2$) with high uniformity. |
| Drying & Curing | Multi-zone temperature control and precise air flow to ensure complete solvent removal without cracking or delamination. | Prevents cracking and ensures the mechanical integrity and adhesion of the electrode film to the current collector (Copper/Aluminum Foil). |
| Calendering (Rolling) | Uses a Cold Rolling Mill to apply precise force, achieving the final target electrode density/porosity. | Maximizes volumetric energy density and improves electrical contact between particles and the current collector. |
| Slitting & Cutting | High-precision slitting (using a Battery Pole Piece Slitter) into custom widths and lengths. | Minimizes burrs and ensures the electrode strip meets the tight dimensional tolerances required for automated winding or stacking. |
Customization Parameters
We work closely with your specifications to control the following critical parameters:
Active Material Loading ($\text{mg}/\text{cm}^2$): Precisely control the amount of material coated onto the foil.
Final Electrode Density ($\text{g}/\text{cm}^3$): Achieved through precise calendering to meet your target energy or power density requirements.
Current Collector Choice: Fabrication on your supplied Current Collector (Copper or Aluminum foil) in various thicknesses.
Coating Mode: Single-sided, double-sided, or intermittent (gap) coating for tab areas.
Final Dimensions: Slitting into custom widths and lengths for Coin Cells, Pouch Cells, or Cylindrical Cells.
