Why lithium batteries explode and catch fire

release time:2024-05-06 Hits:     Popular:AG11 battery

  

  1. Insufficient negative electrode capacity of lithium batteries

  When the capacity of the negative electrode in the positive electrode of a lithium battery is insufficient, the lithium atoms generated during charging cannot be inserted into the interlayer structure of the negative graphite, and will precipitate on the surface of the negative electrode, forming crystals. Long term crystallization in lithium batteries can lead to short circuits, during which the battery cells rapidly discharge, generating a large amount of heat and burning the separator. High temperature can cause the electrolyte to decompose into gas, and when the pressure is too high, the battery cell will explode.

  2. Excessive moisture content

  When charging, water can react with lithium to generate lithium oxide, causing a loss of capacity in the battery cell and making it easy for the cell to overcharge and generate gas. The decomposition voltage of water is low, making it easy to decompose and generate gas during charging. When this series of generated gases increases the internal pressure of the cell, the cell will explode when the outer shell of the cell cannot withstand it.

  3. Internal short circuit

  Internal battery cell short circuit causes high current discharge, generates a large amount of heat, burns out the diaphragm, and causes greater short circuit phenomenon, which will cause the electrolyte to decompose into gas. If the internal pressure is too high, the battery cell will explode.
