As the global energy revolution deepens, the demand for high-performance lithium-ion batteries is growing at an unprecedented rate. However, the cleanliness requirements for the production environments in this cutting-edge manufacturing sector are every bit as stringent as those in the traditional pharmaceutical and semiconductor industries. In the core processes of battery manufacturing, such as electrode coating, cell winding, and packaging, airborne micron-sized particles pose a significant safety hazard. Conductive metallic particles (like iron, copper, and nickel) are especially dangerous; if they land inside a battery cell during assembly, they act like a "micro-bomb." Such a particle can puncture the thin separator, causing a micro-short circuit between the anode and cathode. This can lead to abnormal self-discharge rates, rapid capacity decay, and even localized overheating during cycling, potentially triggering a dangerous thermal runaway event.
Therefore, within the dry rooms that demand extremely low humidity and high cleanliness, implementing rigorous air particle monitoring is the first line of defense for ensuring product quality and safety. Suzhou Sujing's high-sensitivity particle counters provide real-time, precise capture and quantification of environmental contaminants. They help battery manufacturers validate the effectiveness of their environmental control systems (like FFUs) and identify potential contamination sources promptly. By maintaining an ultra-clean production environment, companies can significantly improve the consistency, safety, and cycle life of their battery products, thereby securing a competitive advantage in the fierce global market.
