New Energy Industry Cleanroom Solutions: Lithium Battery, PV, Hydrogen

I. Lithium Battery Manufacturing Solutions

1. Electrode Coating

   • Anti-Static Cleanrooms (ISO Class 6):
     FFUs with ionizers control static (<50V) to prevent lithium cobalt oxide dust adhesion during slurry coating.

   • Humidity Control: Modular cleanrooms maintain 30-40% RH to avoid solvent absorption in anode/cathode drying.

2. Cell Assembly

   • Dry Rooms (ISO Class 5):
     Laminar flow hoods + desiccant systems achieve ≤1% RH for stacking & welding to prevent electrolyte hydrolysis.

   • ESD-Safe Pass Boxes:
     Transfer separators and foils with conductive trays to eliminate static discharge risks.

II. Photovoltaic Production Solutions

1. Silicon Wafer Cutting

   • ISO Class 4 Diamond Wire Saws:
     FFU arrays remove silicon dust (<0.1μm particles) to minimize microcracks and improve wafer yield.

   • Coolant Filtration:
     HEPA-filtered air curtains isolate cutting fluid mist from clean zones.

2. Thin-Film Solar Coating

   • Vacuum-Compatible Cleanrooms:
     Modular chambers with magnetic fluid seals maintain ≤100 particles/m³ during PVD/CVD processes.

   • Glove Box Systems:
     Oxygen-free environments (<1ppm) for perovskite layer deposition.

III. Hydrogen Fuel Cell Solutions

1. MEA (Membrane Electrode Assembly)

   • ISO Class 3 Cleanrooms:
     ULPA-filtered laminar flow workstations for catalyst ink spraying (Pt/C particle control ≤0.05μm).

   • Humidity-Tight Pass Boxes:
     Transfer proton exchange membranes at 50-60% RH to prevent dehydration.

2. Bipolar Plate Fabrication

   • Corrosion-Resistant Cleanrooms:
     Stainless steel modular walls + FFUs with chemical filters for graphite/composite plate machining.

IV. Core Competitive Advantages

• Contamination Control: Achieve <0.1% defect rates in electrode coating via 0.3μm particle removal.

• Energy Efficiency: 35% lower HVAC costs using smart FFU zoning for dry rooms.

• Regulatory Compliance: Meet IEC 62902 (Li-ion ESD), SEMI F21 (PV), and ISO 14644-1 Class 3 standards.

• Ramp-Up Ready: Modular cleanrooms deploy in 3 weeks for gigafactory expansions.
