PRESSURE VENT METAL

A metal pressure vent for LiFePO4 batteries is a safety device designed to release excess pressure that may build up inside the battery pack during abnormal conditions such as overcharging, overheating, or internal faults. These vents are typically made from stainless steel for durability and corrosion resistance, and they help prevent battery swelling, fire hazards, or catastrophic failure.​ Key Features Material: Stainless steel (often 316L grade for high rust resistance)​ Design: Screw-in or snap-fit, with sizes like M12 x 1.5 or M20 x 1.5​ Operating Pressure: Typically set to release pressure at 150–200 kPa, depending on the application​ Temperature Range: Usually rated for -40°C to 200°C, suitable for harsh environments​ Function: Provides both passive and active venting, and some models feature explosion-proof valves for added safety​ Application: Used in EV batteries, energy storage systems, and sealed battery enclosures​
