Which of lithium iron phosphate battery or lithium cobalt oxide battery is safer?

Safety of lithium iron phosphate batteries: Lithium iron phosphate batteries are currently the safest cathode material for lithium batteries, and do not contain any heavy metal elements harmful to the human body. Oxygen is difficult to precipitate in its olivine structure, which improves the stability of the material. The lithium iron phosphate battery pack has undergone strict safety tests and will not explode even in a traffic accident. When the lithium iron phosphate battery is charged and discharged, because the iron ion has a weak oxidation ability and will not release oxygen, it is naturally difficult to undergo a redox reaction with the electrolyte, which makes the charging and discharging process of the lithium iron phosphate battery in a safe environment. The PO bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat or form strong oxidizing substances in the same structure as lithium cobalt oxide. Therefore, the lithium iron phosphate battery has good safety. . Safety of lithium cobalt oxide batteries: After long-term development, lithium cobalt oxide batteries have formed four product lines: cylindrical batteries, polymer soft-pack batteries, aluminum-shell batteries, and steel-shell batteries. These products are used in high-end and medium-sized batteries, respectively. High-end and low-end markets. Lithium cobaltate battery has stable structure, high specific capacity, outstanding comprehensive performance, but its safety is poor, and the cost is very high. It is mainly used in small and medium-sized batteries, and is widely used in small electronic devices such as notebook computers, mobile phones, and MP3/4. Said voltage is 3.7V.
