As the world accelerates toward electric mobility and renewable energy storage, lithium-ion battery manufacturers face unprecedented pressure to improve energy density, enhance safety, and scale production without compromising quality. At the heart of every high-performance battery manufacturing line lies a critical yet often overlooked component: the industrial vacuum system. From electrode slurry degassing to electrolyte injection and final sealing, vacuum technology directly impacts cell consistency, cycle life, and production yield.
Manufacturing Excellence Built Over Two Decades
Zhejiang Yingpa Electromechanical Co., Ltd, operating under the brand InPowerVac, has been at the forefront of vacuum equipment innovation since 2000. Founded by Mr. Liang after recognizing that China's vacuum technology lagged behind imported brands, the company has grown from a visionary startup to a global industrial vacuum pump manufacturer serving world-class enterprises across six continents.
Our commitment to precision engineering is reflected in our world-class facilities. With two production bases in Zhejiang and Hebei provinces covering 70,000 square meters, we operate 92 sets of processing equipment including 30 imported units and 32 Mazak processing centers dedicated exclusively to dry screw vacuum pump manufacturing. Every pump undergoes rigorous testing in our material tensile physics lab, vacuum testing room, dynamic balance lab, and three-coordinate inspection facility before reaching the customer.
This manufacturing capability has earned the trust of industry leaders including Foxconn, Huawei, Samsung (South Korea and Vietnam), Tata Group of India, Aoyama Group, and Russian National Energy. When production lines cannot stop, manufacturers choose InPowerVac.
Complete Vacuum Product Portfolio for Battery Production
Unlike suppliers specializing in a single pump technology, InPowerVac offers a comprehensive range of seven product categories with over 70 models, enabling battery manufacturers to source their entire vacuum infrastructure from one trusted partner.
Oil-free operation with air-cooled and water-cooled options. TA10 titanium alloy models available for corrosive electrolyte environments. Ideal for slurry degassing and electrolyte injection.
Single-stage and two-stage models with ultimate vacuum up to ≤20Pa. British oil mist filter technology ensures clean exhaust. Anti-backflow oil design prevents contamination.
Multi-stage, air-cooled, and gas-circulation cooled models. Used as boosters in combination with backing pumps to achieve high pumping speeds for large-scale production lines.
Oil-free positive displacement pumps achieving pressures down to 10⁻⁷ mbar for high-purity applications requiring ultra-clean vacuum environments.
Pre-engineered and custom-built systems including booster combinations, tank-mounted units, medical-grade systems, and complex multi-pump configurations.
Genuine replacement vanes, vacuum pump oil, oil mist filters, dust filters, and comprehensive spare parts kits to maximize uptime.
Critical Vacuum Applications in Lithium Battery Manufacturing
Lithium-ion battery production demands vacuum performance across multiple stages. InPowerVac pumps are engineered to meet the strictest requirements of each process:
Electrode Slurry Degassing
Before coating, electrode slurries containing active materials, binders, and solvents must be completely degassed to remove micro-bubbles that cause uneven coating thickness, pinholes, and reduced electrode density. Our oil-free dry screw vacuum pump models deliver stable vacuum in the 1-50 mbar range with zero contamination risk, ensuring uniform coating and high compactness of electrode sheets.
Pre-Injection Cell Evacuation
Prior to electrolyte injection, battery cells must be thoroughly evacuated to remove air and moisture. Any residual oxygen or water vapor reacts with electrolyte, causing degradation and reduced cycle life. InPowerVac two-stage rotary vane vacuum pump models achieve deep vacuum levels quickly and maintain consistent pressure across batch after batch.
Post-Injection Vacuum Standing
After injection, cells require stable vacuum conditions to facilitate complete electrolyte penetration into electrodes and separators. Our intelligent frequency-controlled vacuum pump system solutions with PLC integration provide closed-loop vacuum regulation, ensuring every cell receives identical processing conditions.
Pre-Sealing Degassing
Final degassing before pouch cell or prismatic cell sealing removes residual gases generated during formation. This step prevents cell swelling, poor sealing, and potential safety hazards. For high-volume production, our Roots vacuum pump boosters combined with dry screw backing pumps deliver the high pumping speeds needed for multi-chamber degassing lines.
Special Application Requirements
- Lithium Battery Dedicated Models: Our specialized lithium battery vacuum pumps are configured for compatibility with electrolyte vapors and NMP solvent recovery systems.
- Chemical Resistance: TA10 titanium alloy dry screw pumps resist corrosive gases encountered in electrolyte processing.
- Explosion-Proof Designs: For facilities handling flammable solvent vapors, our explosion-proof certified pumps ensure operational safety.
- 24/7 Continuous Operation: All industrial models are engineered for continuous production line duty with imported bearings and oil seals.
Why InPowerVac Stands Apart
InPowerVac pumps incorporate imported bearings and oil seals, British oil mist filter technology, and anti-backflow oil design as standard features. The result is long service life, minimal oil mist emissions, low maintenance costs, and extended consumable replacement cycles that reduce total cost of ownership.
Imported bearings and oil seals, precision machining on Mazak centers, and 100% factory testing ensure consistent performance in demanding production environments.
British oil mist filter technology reduces exhaust emissions by 99%, protecting cleanroom environments and meeting environmental standards.
Economical operation with long consumable replacement cycles, minimal maintenance requirements, and energy-efficient designs.
