LiFePO4（Fosfato de ferro-lítio）

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

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

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

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

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

Trims electrodes into precise dimensions to fit battery cell specifications.

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

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

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

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

Fills electrolyte into cells to enable ion transport between electrodes.

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

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

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

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

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