How to prevent the lithium battery explosion?

by：Vglory 2020-12-05

Lithium battery explosion are basically caused by short circuit battery heating, and the causes of short circuit and overcharge, discharge, positive negative direct docking, electrolyte leakage, etc. So, in the design of lithium battery, can begin from the following points: 1, the battery overcharge to 4 is prohibited. More than 2 v; 2, ban battery in 2. Below 75 v; 3, in the metal shell with the explosion-proof valve; 4, prevent short circuit in the process. Of course, the best way is to have battery protection circuit board design. While this would increase the cost of the manufacture of lithium-ion batteries, but is necessary for the safe use of lithium-ion batteries, all normal lithium battery manufacturer's product proves this design. Lithium iron phosphate battery explosion? Lithium iron phosphate batteries are by far the most safety of lithium ion battery cathode material, oxygen in hard to precipitate the olivine structure, improve the stability of the material. Lithium iron phosphate battery pack after a rigorous safety testing, does not an explosion in the traffic accident. When battery charging and discharging lithium iron phosphate, as a result of iron ion oxidation ability is not strong, will not let out oxygen, nature also cannot REDOX reaction with electrolyte, which made the lithium iron phosphate battery charge and discharge process in a safe environment. Lithium iron phosphate crystals in P - O key, difficult to decompose, even in high temperature or overcharge when also won't like cobalt acid lithium structure collapse fever or strong oxidizing substances, so the lithium iron phosphate battery with good security.
