Manufacturing Process
Electrode Material Preparation

Active materials, binders, and conductive agents are mixed to form a stable slurry, which is precisely coated onto current collectors and dried to form electrodes.

Electrode Processing

Electrodes undergo pressing for optimal density, slitting to required dimensions, and tab welding with protective insulation.

Cell Assembly

Electrodes and separators are stacked or wound, followed by electrolyte injection and hermetic sealing to ensure safety and performance.

Formation & Testing

Initial charge/discharge cycles activate the cell while comprehensive testing verifies voltage, capacity, and safety parameters.

Module & Pack Assembly

Precision-matched cells are assembled into modules with integrated BMS, then combined into final battery packs with rigorous performance validation.
