Key Stages of Lithium-Ion Battery Production
- Electrode Manufacturing
This stage begins by mixing active materials like lithium metal oxides with conductive binders and solvents to form a slurry. The slurry is then coated onto current collectors and dried.
💡 Why vacuum is important: Vacuum pumps remove residual solvents during the drying process, ensuring optimal electrode properties and preventing contamination.
- Cell Assembly
Electrodes are stacked or wound with separators and connected to terminals inside a sealed cell casing.
💡 Why vacuum is important: Cell assembly often occurs in vacuum chambers or dry rooms to eliminate moisture, which can degrade battery performance.
- Cell Finishing
This final stage includes electrolyte filling, formation, aging, and testing to meet strict performance and safety standards.
💡 Why vacuum is important: Vacuum pumps ensure precise electrolyte filling and maintain a contaminant-free environment throughout finishing.
Why Are Vacuum Pumps Critical in EV Battery Production?
Vacuum pumps play a vital role throughout the lithium-ion battery manufacturing process by:
- Removing air and moisture from production chambers
- Supporting solvent recovery during electrode drying
- Enabling clean and controlled environments for assembly and electrolyte filling
- Enhancing the overall battery lifespan and performance
In modern EV battery production lines, precision, cleanliness, and reliability are non-negotiable—and industrial vacuum technology helps manufacturers meet those demands.

Vacuum Solutions Across Key Battery Production Stages
- Mixing: Consistency Starts Here
During the electrode manufacturing process, vacuum pumps are used to mix anode and cathode slurries. Vacuum-assisted mixing helps remove air bubbles, resulting in a homogeneous and consistent slurry.
✅ Why it matters: A uniform mixture is essential for battery performance, stability, and longer lifecycle.
- Drying: Solvent and Moisture Removal
Vacuum drying is crucial for removing solvents and moisture from electrodes. Whether you operate a batch or continuous drying process, our vacuum pumps offer precise control and reliable performance.
✅ Why it matters: Proper drying enhances electrode integrity and prevents degradation during charging cycles.
- Electrolyte Filling & Degassing: Purity and Performance
During cell assembly, vacuum pumps fill the battery cells with electrolytes and remove trapped gases through degassing. This step ensures that lithium-ions flow freely, enhancing charging and discharging efficiency.
✅ Why it matters: Degassing maintains electrolyte purity, which is essential for battery safety and performance.
- Sealing: Airtight for Long-Term Reliability
The final sealing of lithium-ion cells is performed under vacuum to eliminate residual air and moisture.
✅ Why it matters: Sealing under vacuum protects against contamination and ensures a longer battery lifespan.
