Analysis of lithium battery fire extinguishing and lithium battery fire protection precautions

Lithium battery fire and lithium battery fire prevention measures Lithium battery life and lithium battery fire protection precautions? Lithium battery and lithium battery are a great technology, which is expected to bring revolutionary changes and contribute to the storage and supply of electricity around the world Contribute. However, the risk of fire (explosion) cannot be ignored. Therefore, we should adopt the necessary lithium battery and lithium battery storage methods to reduce risks and improve safety. Lithium batteries, including lithium batteries, have the advantages of high cost performance, light weight, and environmental protection, but because of the large amount of energy stored, there are also high risks of fire and explosion. Whether it is a large battery in the energy storage industry, a new electric energy battery, or a small battery in electronic equipment, there are certain risks. When energy is stored in the main space, it is often released, sometimes violently. Therefore, in the entire battery life cycle, reasonable fire protection and lithium battery saving methods should be considered. This profession brings new challenges, including battery manufacturing, transportation and logistics, warehouse management, and battery use. For colleagues engaged in risk control and fire protection, how to quantify risks and how to effectively protect them has become a new challenge. Lithium batteries and lithium batteries are called similar batteries, but they are used in different ways. Lithium batteries cannot be charged. They contain extremely flammable metallic lithium. Lithium batteries are commonly used in military, medical and electronic equipment. Door fan test, air tightness test, FM fire pump, CE certification for fire protection. Lithium battery, rechargeable. It is lighter than lithium batteries and provides a high energy storage density. Lithium batteries do not contain metallic lithium, but contain lithium ions and a highly flammable electrolyte (liquid). Applications include notebook computers, mobile phones, new energy vehicles, medical equipment and energy storage systems. With the rapid increase in the use of lithium (ion) batteries, the risk of fires is also widespread throughout their life cycle. From manufacturing, logistics, warehousing, to end users, everyone should have a higher understanding of the fire risks and electricity brought by this wonderful thing. Every link in the battery supply chain should have a responsible approach to ensure safety. Ignition characteristics of lithium batteries Lithium batteries will spontaneously ignite due to overheating and then explode. Causes of overheating include short circuits, rapid discharge, overcharging, manufacturing defects, poor design, or mechanical damage. Overheating will lead to a thermal runaway process. In this process, the exothermic reaction inside the battery will cause the temperature and pressure inside the battery to rise rapidly, thereby wasting energy. Once a cell loses thermal control, it will release enough heat to make neighboring cells lose thermal control. When each cell divides in turn and releases its contents, it will cause a repetitive fire. This will cause the flammable electrolyte in the battery to explode. If a disposable lithium battery is used, it will release combustible metal lithium. Therefore, there will be a huge problem. These fires cannot be regarded as normal fires, and targeted training, prevention and control planning, reasonable storage and establishment of lithium battery rescue systems are required. Data on the combustion characteristics of large batteries are limited. However, we can guess that when the battery enters a thermal runaway state, the thermal runaway transmission will attack the recognizable symbols; the battery also works in a certain way. The fire may gradually go out or explode. Both types of accidents and their negative by-products (explosive shrapnel, molten metal, incineration electrolyte and other substances) can be managed and handled by establishing an appropriate storage and transportation environment for the battery. Systems using lithium (ion) batteries may continue to use and develop some kind of control and lithium battery survival system to reduce the chance of negative events, and then control the risks to make the battery system safe for users. Lithium battery fires have occurred all over the world. These fires occur in energy storage systems (wind energy, solar energy, etc.), battery test environments, transportation and storage, and many other areas. Many electric vehicles will automatically ignite battery packs, and many battery packs have caught fire or exploded. Although many in the automotive, fire research and emergency response professions believe that the fire risk of lithium battery-powered cars is no better than that of traditional vehicle systems, it is generally recognized that the risk of by-products is ignition, heat, and flames, and fires caused by lithium batteries.
