Lithium Ion Battery Manufacturing Process In 20 Steps
To deliver reliable and rechargeable lithium ion batteries, we implement a complete manufacturing process with clearly defined steps and quality controls.
Lithium Ion Battery Construction
Precisely controlled battery cell assemly process ensures consistent structure, stable internal resistance and reliable current paths across batches.
01 WINDING
Enables high production efficiency and stable cell consistency, well-suited for standard formats of lipo battery cells requiring balanced energy density, discharge performance and cost control.
02 MICRON-LEVEL STACKED
Provides higher space utilization and uniform current distribution inside lithium ion battery, ideal for high-energy-density or custom-shaped cells where precise layer alignment is critical.
03 TAB WELDING
Ensures low contact resistance and strong mechanical bonding between battery tabs and electrodes, supporting reliable current flow and long-term electrical stability.
How We Realize?
—— High Quality Lithium Ion Battery
Slurry Homogenization
Ensures uniform dispersion and stable viscosity, laying the foundation for consistent electrode quality and repeatable batch
Coating Monitoring
Tracks coating thickness in real time and reduces coating deviation, improving capacity consistency and lowering defect risk.
Lamination Alignment
Improves layer alignment and current-path uniformity, supporting lower variation in internal resistance and more predictable power output.
Uniform SEI Formation
Promotes uniform SEI formation in lithium ion batteries and stabilizes electrochemical behavior, helping reduce performance drift and improve long-term cycling stability.
Li-ion Battery Types
We support multiple lithium ion battery types and align chemistry choice with your environmental conditions, duty cycle and certification requirements
