Are lithium batteries toxic and dangerous?

It is known that most of the new energy vehicles promoted in my country (including pure electric vehicles and plug-in hybrid vehicles) use lithium batteries, of which lithium iron phosphate accounts for 80% and 90%, and ternary lithium batteries are also used in passenger cars. Began to use it on a large scale. In response to the claim that lithium batteries are highly toxic and dangerous goods in the online article, Wang Fang refuted that compared to traditional batteries such as lead-acid, nickel-chromium, and nickel-metal hydride, lithium batteries do not contain any toxic and harmful heavy metals such as lead, mercury, and cadmium. Elements and substances are relatively less polluted. And its electrolyte is organic solvent and lithium salt, mostly non-toxic or low-toxic; but lithium battery analysis or hydrolysis products are hydrofluoric acid and other fluorine-containing compounds, which are corrosive and toxic. Regarding the highly toxic lithium battery, Liu Haojie, a researcher-level senior engineer at the 18th Research Institute of my country Electronics Technology Group, said that the lithium battery itself does not contain highly toxic substances, and the carbon of the negative electrode and the metal oxide of the positive electrode are basically non-toxic. Since lithium batteries belong to a sealed system, these substances will not be exposed to normal use. In any case, its impact is far less than that of lead-acid batteries, which are currently the most widely used.
