Battery Manufacturing Plant Design

Lithium-ion and advanced battery plants demand the strictest environmental control, structural precision and safety engineering of any industrial facility type. We deliver multi-discipline engineering across cell, module and pack manufacturing at gigafactory scale.

Engineering Challenges

Battery facilities combine extreme dry-room conditions, solvent processing, high power demand and Li-ion fire hazard — all inside a structure that must support multi-tonne coating, roll-press and formation equipment with super-flat floor requirements.

Key Technical Requirements

Environmental Control

• Ultra-low humidity dew points (-40°C to -70°C) for electrode coating
• ISO 14644 cleanroom classification (Class 1000-10000)
• Particle filtration down to 0.5 microns
• Electrostatic discharge (ESD) flooring
• Personnel and material airlocks with interlocking systems

Structural & Mechanical

• Super-flat floors (±5mm over 100m) for precision coating/pressing
• Design loads: 50-100 kPa for formation/test equipment
• Vibration isolation for sensitive manufacturing zones
• Corrosion resistance in NMP/DMF solvent environments
• Emergency egress and fire compartmentation

Electrical & Process Utilities

• Redundant power feeds (N+1 minimum for dry rooms)
• 3-5 MW+ demand for large-scale cell production
• Chilled water loops for cooling NMP, electrode wash, formation heat
• Process water (DI/RO) for electrode slurry prep
• NMP solvent recovery with 90%+ recycle rate
• Compressed air (ISO 8573-1 Class 1) for pneumatic equipment

Safety & Fire Protection

• Li-ion thermal runaway detection (formation/test areas)
• Halon-alternative fire suppression in dry rooms
• Water spray systems with non-conductive nozzles
• Separation distances per NFPA 70B
• Emergency shut-down procedures for solvent atmosphere

Our Engineering Approach

We lead with production throughput as the primary design driver. Architecture, structural, MEP and process utilities are co-designed around material flow, equipment vendor requirements and the phased ramp-up characteristic of battery gigafactories.

Design Workflow

1. Pre-FEED: Capacity planning, site evaluation, utility headroom analysis
2. FEED: Process flow sheets, equipment selection, preliminary layouts
3. Detailed Design:
   • 3D BIM with clash-free coordination
   • Structural FEA for floor flatness and vibration
   • HVAC simulation for dew point control
   • Electrical load flow and transient studies
4. Construction Support: Commissioning coordination, dry-room qualification
5. Ramp-Up Support: Digital twin monitoring for throughput optimization

Technology Stack

• BIM: Revit with Plant 3D for coordinated MEP/structural
• HVAC Simulation: Computational Fluid Dynamics (CFD) for humidity control
• Structural Analysis: STAAD, SAP2000 for super-flat floor design
• Electrical: ETAP for load flow, short-circuit and protection
• Digital Twin: IIoT sensors + real-time dashboards for ops monitoring

Typical Project Scope

Facility Size: 50,000–500,000 m² (cell + module/pack manufacturing)

Production Capacity: 50–500 GWh/year (lithium-ion cells)

Key Areas:

• Electrode preparation (mixing, coating, drying)
• Cell assembly (stacking, case filling, tab welding)
• Formation & testing (cycling, performance grading)
• Module & pack assembly (thermal management, BMS)
• Recycling/scrap processing
• Utilities & support services

Timeline: 18–36 months from FEED to production ramp
