Why does a lithium power battery burn spontaneously?

New energy vehicles have now become the mainstream of the market. Lithium batteries, which are also the core of energy storage devices, have also received attention from everyone. However, compared with technical problems and the battery life of lithium batteries, people are still more. A concern, that is, safety issues, the problem of spontaneous combustion of lithium batteries has become a focus of concern for consumers with the safety of the use of automobiles. Why does a lithium power battery burn spontaneously? Is the electric car safe and will it explode like a mobile phone battery? Can it be safely and safely used? So many questions are in front of everyone, who will give this answer.

Why is a lithium power battery self-igniting? Basically, because lithium itself is the most active metal among all metals, the lithium-ion battery has a small volume and high energy density, making it the first choice for electric vehicles because lithium is too lively. It will be exposed to the air to produce a chemical reaction that will explode and burn. But this does not mean that the lithium power battery we use is self-igniting because of the relevant protective measures. In actual operation, scientists have tried every means to prevent the conversion of lithium ions into lithium metal in the electrolyte. And the metal lithium is locked in graphite or lithium compound, and at the same time, in order to prevent the entry of air, some protective measures are taken, which makes the lithium metal not explode when it wants to contact with oxygen. Therefore, even though lithium metal is too active, it is easy to spontaneously ignite when exposed to oxygen. However, scientists have strictly controlled this situation. The emergence of various protective measures also shows that lithium batteries for electric vehicles do not easily ignite spontaneously.
