What chemical substances are included in lithium batteries?

Does the lithium battery have the material conditions for explosion? By comparing the various elements required for blasting, the composition and reaction process of the lithium battery are analyzed. What kinds of chemicals are in lithium batteries? Are they enough to cause explosions? Liu Wei, an expert from the safety testing department of my country's Tyre Laboratory, said: Generally speaking, lithium batteries in mobile phones are also called battery packs or battery packs. It is mainly composed of a battery and a maintenance circuit. The battery is composed of a positive electrode and a negative electrode, an electrolyte, a gap, and a casing. The widely used positive electrode material is lithium cobalt oxide. Under certain conditions, lithium cobalt oxide will attack the differentiation and separation of lithium ions. The negative electrode material is graphite, which has many small spaces in the molecular structure and is a storage battery for lithium ions. The electrolyte is usually a mixed organic solvent, and the common electrolyte is a salt called lithium hexafluorophosphate. In terms of barrier function, it is important to separate the positive and negative electrodes to prevent short circuits caused by the contact between the north and south poles. At present, the data of the barrier is generally a polyolefin porous polymer membrane, and the micropores on the membrane are for the free passage of lithium ions. When the battery is charged, the lithium ions on the positive electrode of the battery move to the negative electrode through the electrolyte and are embedded in the micropores of the carbon layer. The more lithium ions embedded in the negative electrode, the stronger the charging capacity of the battery. Similarly, when the battery is discharged, the lithium ions embedded in the negative electrode carbon escape and return to the positive electrode. This completes the charging and discharging process of the lithium battery. From the perspective of the internal elements of the battery, it now includes carbon, oxygen, and simple burning electrolyte. These substances are sealed in a small space. If there are certain conditions, they may release huge heat and gas due to chemical reactions. , May explode. But this is not to say that the existence of these elements will explode. Shi Pengfei, a professor of applied chemistry at Harbin Institute of Technology and an expert in lithium battery research, told reporters that only under certain environmental conditions can lithium ions, electrolytes, and barriers interact with each other, showing disorderly changes until they explode.
