Will the lithium battery burst if it is punctured?

Lithium batteries are toxic 1. The electrolyte solution is toxic. Electrolyte is a kind of organic volatile liquid with obvious corrosiveness. 2. Lithium battery is composed of positive electrode powder, negative electrode powder, conductive powder, binder powder, electrolyte, organic solution, etc. The cobalt in the positive electrode powder is a toxic metal substance, the organic dispersant is a toxic organic solvent, and the electrolyte is the most toxic and corrosive component in lithium batteries, which has a direct impact on the human body. Lithium batteries will burst if they are punctured. There are different answers. First of all, if it is not positive lithium (lithium ions cannot completely crystallize through carbon bonding), the lithium ions are in a stable state, and it is not because the lithium ions react with air to attack. Even the evolution of lithium is not an important cause of incineration. The cause of spontaneous combustion is that the battery is damaged 1. The metal weapon battery is short-circuited; 2. External damage will form a barrier and damage the battery short-circuit. When there is a huge amount of heat in the DC short circuit, the battery will lose control of the heat, and the temperature will rise to more than 300 degrees Celsius within milliseconds. The important flammable substance in lithium batteries is electrolyte, which has an ignition point of about 130 degrees Celsius and does not contain flame retardants. Almost all products contain flame retardants. The current large-scale electric vehicle accidents are caused by battery damage, electrolyte leakage and incineration. And the skill system, called lithium battery, is roughly divided into lithium cobalt and lithium manganese, lithium ternary, iron, etc.The thermal runaway temperature of lithium cobalt and ternary is lower than 300 degrees Celsius, about 400 degrees Celsius, and lithium manganese lithium iron is higher than 700 degrees Celsius, and recent iron-lithium-manganese binary products, depending on the doping, the key to thermal runaway is 400-600 degrees Celsius. This is a big difference, which is one of the reasons why iron lithium is safe. Therefore, in the national standard for lithium iron, the metal acupuncture test is a safety test that must be done. In other words, lithium iron batteries that meet the requirements of our country should not burn or explode after acupuncture. I did a lot of this experiment without any objections. Even after acupuncture, I can continue to use some products. The stab wound mentioned in the topic further amplifies the damage. I have done this experiment before, but the battery did not burn out or explode. In recent years, in some third-party inspections, regulatory agencies have required the disassembly of batteries to check for internal parallel structures. The specification is whether there is only one battery in a unified electrolyte structure. We also grabbed the battery several times to explain, but there was no safety issue. Therefore, the lithium iron battery products meet the national standards. Due to its chemical characteristics and the protection after adding flame retardants, the knife is not attacked by spontaneous combustion. Other products cannot be guaranteed. Of course, because I am mainly engaged in lithium iron here, I am not familiar with the specifications of lithium manganese and other products, and I also hope that the additional answers from my peers can be correct. In theory, the metal foreign body puncture experiment is the basis of the experiment. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
