Roll-to-Roll Electrode Coating Systems: Ensures uniform coating thickness and high reproducibility for large-scale production.
Drying and Calendering Equipment: Controlled drying ovens and precision calendering machines optimize electrode porosity, density, and surface smoothness.
Advanced Cell Assembly Lines: Robotic or semi-automated assembly stations handle pouch, cylindrical, or prismatic cells in controlled atmospheres to minimize contamination.
Formation and Testing Units: Formation presses, SEI layer formation systems, and battery cyclers ensure stable electrochemical performance and quality assurance.
Environmental Control: Gloveboxes and dry rooms maintain low moisture and oxygen levels critical for sodium battery stability.
Safety and Automation: Integrated sensors, interlocks, and monitoring systems guarantee safe and efficient operations throughout the plant.
Manufacturing Process
The sodium battery manufacturing plant process involves several key stages to produce high-quality batteries:
Slurry Preparation: Active materials, binders, and conductive additives are precisely mixed using planetary mixers or ultrasonic dispersers to form consistent electrode slurries.
Electrode Coating and Drying: Slurries are coated onto metal current collectors with precision roll-to-roll systems and dried under controlled temperature and humidity conditions.
Electrode Calendering: Coated electrodes are compressed to achieve desired thickness, density, and mechanical integrity, improving energy density and cycle performance.
Cutting and Stacking: Electrodes are cut into precise dimensions and stacked or rolled, depending on the battery design.
Cell Assembly: Pouch, cylindrical, or prismatic cells are assembled in dry rooms or gloveboxes with strict moisture and oxygen control.
Electrolyte Filling and Sealing: Sodium-based electrolytes are filled, and cells are hermetically sealed to prevent contamination.
Formation and Testing: Cells undergo controlled charge-discharge cycles, capacity testing, and quality checks to ensure reliable performance.
