Explosion-proof technology principle of lithium battery

　　Lithium battery explosion-proof technology is realized through those principles to prevent danger from occurring?

　　Lithium is the smallest and most active metal on the chemical periodic table. Because of its small size and high capacity density, it is widely welcomed by consumers and engineers. However, the chemical properties are too active, which brings extremely high risks. When lithium metal is exposed to the air, it will react violently with oxygen and explode. In order to improve safety and voltage, scientists invented materials such as graphite and lithium cobalt oxide to store lithium atoms. The molecular structure of these materials forms a small nano-scale storage grid that can be used to store lithium atoms. In this way, even if the battery shell ruptures and oxygen enters, the oxygen molecules are too large to enter these small storage cells, so that the lithium atoms will not come into contact with the oxygen and avoid explosion. This principle of lithium-ion batteries enables people to achieve safety while achieving high capacity density.　　 Lithium battery explosion-proof technology is based on those principles to prevent danger. 　　 When charging a lithium ion battery, the positive lithium atoms lose electrons and are oxidized to lithium ions. Lithium ions swim to the negative electrode through the electrolyte, enter the storage cell of the negative electrode, and obtain an electron, which is reduced to lithium atoms. When discharging, the whole procedure is reversed. In order to prevent the positive and negative poles of the battery from directly touching and short-circuiting, a diaphragm paper with many pores is added to the battery to prevent short-circuiting. A good diaphragm paper can also automatically close the pores when the battery temperature is too high, so that lithium ions cannot pass through, so as to waste martial arts and prevent danger.
