Spontaneous combustion of lithium batteries

New energy vehicles have become the mainstream of the market at present. The same as the core position of energy storage device, lithium battery also has grabbed the attention, but compared to technical problems and the life of lithium-ion batteries, people still have one more concern about safety. The use of spontaneous combustion of the lithium-ion batteries as car safety problems become the focus of the consumers and a concerned. Why do lithium batteries spontaneously combust? Are electric cars safe and will they explode like cell phone batteries? Can it be used safely? With so many questions, who will give the answer?

The reason why lithium batteries spontaneously ignite is basically because lithium itself is the most active metal among all metals. The small size, high capacity and high energy density of lithium ion batteries make it the first choice for electric cars, because lithium is so reactive that it will be exposed to the air to produce chemical reactions, thus resulting in explosion and combustion. However, this does not mean that the lithium batteries we use are spontaneously combustible, because of the relevant protective measures. In practice, scientists have tried to prevent the lithium ions in the electrolyte from turning into lithium metal. And the lithium metal is locked in graphite or lithium compounds, but also to prevent the entry of air, a number of protective measures, which makes the lithium metal, will not want to contact with oxygen and explosion. Therefore, even though lithium metal is too lively, it is easy to spontaneously ignite and explode when it encounters oxygen. However, scientists have also strictly controlled this situation. The emergence of various protective measures also indicates that lithium batteries in electric cars will not spontaneously ignite easily.
