High Energy Density Battery

Active materials, conductive agents, and binders are uniformly dispersed in solvent to form electrode slurry.

Homogenized slurry is coated onto aluminum foil and dried to form electrode sheets.

Coated electrodes are compressed to specified thickness under controlled pressure.

Post-calendering electrodes undergo vacuum drying to remove residual moisture.

Electrode sheets are precision-cut to required dimensions.

Anodes, cathodes, and separators are stacked in “Z” configuration to form cell cores.

Multi-layer electrode tabs are aligned, ultrasonic-welded, and insulated with adhesive tape.

Cell cores are housed in pre-formed aluminum laminate pouches with top/seal side sealing.

Final moisture removal from assembled cells prior to electrolyte filling.

Precise injection of electrolyte solution into dry cells.

Initial closure of electrolyte injection port.

Electrochemical activation to establish Solid Electrolyte Interphase (SEI) layer on anode.

Gas pocket removal and hermetic terminal sealing.

Charge-discharge cycling for capacity measurement and performance binning.

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.
