Production Flow of Battery Cells

Mixing​
Step 1 :Mixing​

Blends active materials, binders, and solvents into a uniform slurry to ensure consistent electrochemical performance.

Coating
Step 2 :Coating

Spreads the slurry onto metal foils (anode/cathode) with precise thickness control for optimal energy density.

Drying
Step 3 :Drying

Removes solvents from coated electrodes to stabilize material adhesion and prevent cracking.

Coating&Winding
Step 4 :Coating & Winding

Combines anode/cathode layers with separators and winds them into a compact jellyroll structure.

Pressuring Film
Step 5 :Pressuring Film

Compresses electrodes to enhance density and conductivity while maintaining porosity for ion flow.

Making Film​
Step 6 :Making Film​

Trims electrodes into precise dimensions to fit battery cell specifications.

Stacking
Step 7 :Stacking

Aligns anode/separator/cathode layers in a Z-fold pattern to maximize space efficiency.

Welding
Step 8 :Welding

Joins electrode tabs using laser welding to minimize resistance and ensure current stability.

Encapsulation​
Step 9 :Encapsulation​

Seals cells in aluminum-plastic film to protect against moisture, dust, and mechanical stress.

Baking
Step 10 :Baking

Removes residual moisture from cells under vacuum to prevent electrolyte degradation.

Injection
Step 11 :Injection

Fills electrolyte into cells to enable ion transport between electrodes.

Charging
Step 12 :Charging

Activates cells with initial charging to form a stable solid-electrolyte interface (SEI).

Extracting Air​
Step 13 :Extracting Air​

Evacuates gas from cells to eliminate air pockets and ensure full electrolyte penetration.

Charging and Discharging​
Step 14 :Charging and Discharging​

Cycles cells to stabilize performance and screen out defects before final assembly.

Testing
Step 15 :Testing

Validates capacity, impedance, and safety (e.g., overcharge, short-circuit) under strict protocols.

Assembling​
Step 16 :Assembling​

Integrates cells into modules or packs with BMS, wiring, and thermal management systems.

FAQs

What affects the lifespan of a battery cell?

Mainly charge/discharge cycles and depth. Frequent full charges and discharges accelerate aging. Extreme temperatures (too high or too low) can also shorten lifespan.

Is it normal for a battery cell to heat up while charging?

Mild heating is normal due to energy conversion. But if it gets too hot, smells strange, or heats up suddenly, it may be aging or incompatible with the charger—stop charging immediately.
