The Role of UV Coatings in Battery Cell Safety
Lithium-ion batteries generate heat during charging and discharging, UV coating battery cell and improper thermal management can lead to thermal runaway—a dangerous chain reaction causing fires or explosions. acts as a protective barrier, preventing short circuits and dissipating heat efficiently. By forming a thin, durable layer (2–5μm) on electrodes and separators, UV-cured materials ensure stable operation in extreme temperatures (-40°C to 150°C) while maintaining high dielectric strength (up to 1,000V/μm).
