EV Battery Manufacturing Static and Contamination Control Solutions

EV Battery Applications We Support

• Slurry Preparation – Moisture intrusion, particle attraction in mixing tanks
• Coating & Drying – Sub-micron contamination on active layers
• Calendering – Embedded particles from high-pressure rolling
• Slitting & Electrode Cutting – Metallic burrs and dust clinging to charged surfaces
• Cell Assembly – Contamination between layers, reduced dielectric strength
• Electrolyte Filling & Sealing – Uneven wetting from residual charges
• Module Assembly – ESD damage to battery management systems (BMS)
• Final Testing & QA – Latent defects affecting yield and long-term safety

What Regulations Address Static Control in the Industry?

There aren’t many regulations that exclusively target static electricity—but several standards and guidelines from related industries (electronics, hazardous atmospheres, general manufacturing) are highly relevant and widely applied for safe, contamination‑free EV battery production.

• ANSI/ESD S20.20 – Electrostatic Discharge Association standard for designing, implementing, and maintaining an ESD control program.
• IEC 61340-5-1 – International equivalent to S20.20, used for global compliance.
• NFPA 77 – Recommended Practice on Static Electricity (U.S.).
• IEC 60079 – Explosive atmospheres; parts can be relevant if solvents, combustible dusts, or flammable vapors are present (e.g., electrolyte handling).

While not directly about static control, these regulations ensure overall battery safety and are often used alongside static-control measures in manufacturing.

• UL 1642 – Safety standard for lithium batteries (cells).
• UL 2580 – Safety requirements for batteries in electric vehicles.
• IEC 62619 – Safety requirements for industrial lithium-ion batteries.
• OSHA 29 CFR 1910 – U.S. workplace safety standards, includes electrical safety and PPE requirements.
• EPA 40 CFR Part 461 – Battery manufacturing effluent guidelines (mainly environmental waste and discharge control).
