3 :Drying
Removes solvents from coated electrodes to stabilize material adhesion and prevent cracking.
4 :Coating & Winding
Combines anode/cathode layers with separators and winds them into a compact jellyroll structure.
8 :Welding
Joins electrode tabs using laser welding to minimize resistance and ensure current stability.
7 :Stacking
Aligns anode/separator/cathode layers in a Z-fold pattern to maximize space efficiency.
6 :Making Film
Trims electrodes into precise dimensions to fit battery cell specifications.
5 :Pressuring Film
Compresses electrodes to enhance density and conductivity while maintaining porosity for ion flow.
9 :Encapsulation
Seals cells in aluminum-plastic film to protect against moisture, dust, and mechanical stress.
10 :Baking
Removes residual moisture from cells under vacuum to prevent electrolyte degradation
11 :Injection
Fills electrolyte into cells to enable ion transport between electrodes.
12 :Charging
Activates cells with initial charging to form a stable solid-electrolyte interface (SEI).
16 :Assembling
Integrates cells into modules or packs with BMS, wiring, and thermal management systems.
15 :Testing
Validates capacity, impedance, and safety (e.g., overcharge, short-circuit) under strict protocols.
14 :Charging and Discharging
Cycles cells to stabilize performance and screen out defects before final assembly.
13 :Extracting Air
Evacuates gas from cells to eliminate air pockets and ensure full electrolyte penetration.
