Cut and shape raw materials to produce anode components, such as ribbons, films, or sheets. Weld or bond components together to form anode structures.

• Use specialized equipment and techniques, such as stamping, punching, and welding.
• Inspect and test components to ensure they meet specified dimensions and quality standards.

2. Assemble Anode Subcomponents

Assemble anode subcomponents, such as current collectors, active materials, and coatings. Follow established assembly procedures to ensure precision and consistency.

• Apply adhesives, coatings, or sealing agents to improve electrical connections and prevent corrosion.
• Use specialized tools and equipment to perform complex assembly operations.

3. Test and Inspect Anodes

Conduct tests and inspections to ensure anodes meet performance and quality specifications. Use testing equipment, such as electrical analyzers and microscopes.

• Identify and correct any defects or non-conformances.
• Prepare documentation and reports on anode performance and testing results.

4. Maintain Equipment

Perform preventive maintenance and repairs on equipment used in anode fabrication and assembly. Ensure equipment is calibrated and operating properly.

• Follow established maintenance schedules and procedures.
• Troubleshoot equipment malfunctions and make necessary repairs.
