Application of Ozone in Humidity Control for Lithium Battery Workshops

In lithium battery workshop dehumidification, ozone does not directly perform dehumidification. Instead, it acts as an auxiliary means to support dehumidification systems in maintaining stable and clean low-humidity environments.

Lithium battery production requires strict control of environmental humidity below 40%RH to prevent reactions between LiPF₆ in the electrolyte and moisture, which generates HF, leading to electrolyte decomposition and electrode corrosion. High humidity environments also promote the growth of microorganisms like bacteria and mold, whose metabolic byproducts may contaminate electrode materials or electrolytes, accelerating battery performance degradation. Additionally, residual organic pollutants (e.g., oil stains, volatile compounds) in the workshop may combine with moisture, reducing dehumidification equipment efficiency.

Ozone’s strong oxidizing properties enable rapid inactivation of microorganisms (bacteria, mold, etc.), curbing their growth in high-humidity environments and lowering contamination risks. It also decomposes organic pollutants, preventing interference with dehumidification system operations or adverse reactions with moisture. By purifying workshop air, ozone assists dehumidification systems in more stably maintaining low-humidity conditions, indirectly safeguarding electrolyte stability and battery performance.

Note: Ozone concentration must be strictly controlled (typically ≤0.1mg/m³) to avoid equipment corrosion or health hazards to operators. It should work in coordination with dehumidification systems to ensure both effective dehumidification and environmental cleanliness.
