Lithium battery fire extinguishing agent

Abstract

Provided is a lithium battery fire extinguishing agent. The lithium battery fire extinguishing agent is characterized by comprising, by weight, 2-3 parts of fluorinated alkyl betaine, 15-25 parts of lauroylamide propylbetaine, 0.5-2.5 parts of organosilicon quaternary ammonium salt, 5-15 parts of dodecylbetaine, 40-55 parts of a compound of ethylene glycol and glycerol, 5-20 parts of a compound ofdiethylene glycol monobutyl ether and n-butanol, 5-10 parts of urea, 0.03-0.08 part of xanthan gum, 0.5-1 part of sodium alginate, 2-10 parts of edetate disodium or ethylenediaminetetraacetic acid orsodium citrate, 0.1-1 part of triethanolamine and 80-100 parts of water. The lithium battery fire extinguishing agent is extremely low in corrosivity, capable of not damaging storage tanks, fire-fighting equipment and protected objects, capable of cleaning residues easily after extinguishment and capable of achieving autonomous degradation, and particularly suitable for aluminum battery extinguishment.

Description

technical field [0001] The invention relates to the field of fire extinguishing agents, in particular to a lithium battery fire extinguishing agent. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium-ion batteries are generally batteries that use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and non-aqueous electrolytes. With the widespread use of digital products such as mobile phones and notebook computers, lithium-ion batteries have been widely used in such products due to their excellent performance, and are gradually developing into other product application fields. Lithium-ion batteries ha...

AI Technical Summary

Problems solved by technology

"Short circuit is divided into two types: internal short circuit and external short circuit. The cause of external short circuit may be caused during storage, transportation, etc., while internal short circuit is the problem of the product itself." These problems include: during the production process, the environment is not clean, Contamination of other substances on the positive and negative electrodes; the internal diaphragm cannot effectively separate the positive and negative electrodes, and there are defects

If a large number of batteries are stored together in the factory, it will cause a chain fire and explosion

[0004] Due to the internal spontaneous combustion and explosion of the battery, dry powder fire extinguishers cannot be used at this time. At present, the best way is to cool down with water, and there is no targeted and effective fire extinguishing product.
