There are five common reasons for lithium ion battery explosion

source:other news release time:2022-11-03 Hits:0     Popular:Lithium-ion battery wholesale

  

  1. The cathode capacity of lithium ion battery is insufficient. When the cathode capacity of the positive part of the lithium ion battery is insufficient, the lithium atom cannot be inserted into the interlayer structure of the negative graphite during charging, and crystals will precipitate on the negative surface. In lithium ion batteries, long-term crystallization can lead to short circuits. At this time, the battery will discharge rapidly, generating a lot of heat and burning the diaphragm. High temperature will decompose electrolyte into gas. When the pressure is too high, the battery will explode

  2. When the water content is too high, the water will react with lithium to generate lithium oxide, which will lead to the loss of battery capacity and easy to overcharge the battery and generate gas. The decomposition voltage of water is low, so it is easy to decompose and generate gas when charging. When the gas generated in this series will increase the internal pressure of the battery, the battery will explode when the battery shell cannot bear

  3. Internal short circuitInternal battery short circuiting causes high current discharge, generates a lot of heat, burns the diaphragm, and leads to greater short circuit, which will decompose the electrolyte into gas. If the internal pressure is too high, the battery will explode

  4. When the overcharge cell of a lithium ion battery overcharges, the excessive release of lithium from the positive electrode will change the structure of the positive electrode. The excessive release of lithium will easily prevent it from being inserted into the negative electrode, which will easily lead to lithium precipitation on the surface of the negative electrode. In addition, when the voltage reaches above 4.5V, the electrolyte will decompose and generate a large amount of gas. All of this could lead to an explosion

  5. External short-circuit External short-circuit may be caused by incorrect connection of positive and negative poles. Due to external short circuit, the discharge current of the battery is large, which will heat the battery. High temperature will shrink or completely damage the diaphragm in the battery, resulting in internal short circuit and explosion.
