The United States has developed a new type of sensor to prevent lithium-ion battery explosion

Introduction: The explosion-proof system combines an automatically controlled door lock and an intelligent controller, which can control fire safety input signals such as smoke, heat or gas detectors. It is suitable for cabinets ranging from 50 kilowatts to several megawatts. A research team from the US Department of Energy's Pacific Northwest National Laboratory (PNNL) created a sensor system to detect fire hazards in lithium-ion storage systems. PNNL scientist MattPaiss said: 'The system is designed for lithium-ion storage because lithium-ion storage is the most risky chemical composition, especially for outdoor cabinet-style enclosures where batteries enter from the outside.' He pointed out that the The system is suitable for cabinets ranging from 50 kilowatts to several megawatts. According to researcher Allan Tuan, the system uses commercially available components and is easy to install on new or refurbished equipment. He said: 'The cost depends on the size of the battery. End users or operators can obtain their specific site or facility system through PNNL's low-cost and fixed fee license.' This sensor system is called IntelliVent, which is a type of sensor system. Explosion-proof technology, which combines an automatically controlled door lock and an intelligent controller, which can control fire safety input signals such as smoke, heat or gas detectors. According to reports, the sensor can detect the toxic combustible gases released by the lithium-ion battery when its liquid electrolyte evaporates and pushes it to reach a critical temperature. Paiss said: 'Depending on the size of the battery, these gases will be released very quickly in a very large volume, and may cause a fire or even an explosion.' The system can open all the cabinet doors before the gas accumulates, creating a safer At the same time, it also prevents the operation and maintenance workers from operating in a critical situation. The technology will now be tested by the Arlington Microgrid and Clean Energy Center in Everett, Washington, which will use the proposed system to retrofit the existing 1.2 MW battery.
