Protection Measures for Spontaneous Combustion of Lithium Batteries

source:Industry News release time:2024-02-22 Hits: Popular:AG11 battery

　　Shell protection: In order to prevent air from entering, lithium batteries are sealed in sealed containers and usually equipped with stainless steel and aluminum alloy shells to prevent external damage. For example, Tesla's electric vehicles even use titanium alloy protective plates to prevent damage to battery containers during vehicle use, especially in traffic accidents.

　　Diaphragm blocking protection not only prevents external damage, but also prevents damage from inside the battery.

　　Usually, in order to prevent short circuits caused by direct contact between the positive and negative poles of the battery, there is a layer of separator inside the battery, which separates the positive and negative poles and allows charged ions to pass through.

　　However, in lithium batteries, the separator also carries another protective function. When the battery temperature is too high, the diaphragm gap will automatically close, making it impossible for lithium ions to pass through, thereby terminating the entire battery reaction. This prevents the problem of high voltage generated by the gasification of the electrolyte in the battery due to high temperature, which can damage the sealing structure of the battery.

　　Overcharge voltage protection not only blocks the air, but also prevents the leakage of metal lithium from the electrode.

　　Scientists store and lock the metal lithium formed during charging and discharging through the nano gaps and lattice mechanisms of electrode materials.

　　In this way, even if the battery casing ruptures and oxygen enters, the oxygen molecules are too large to enter these small storage cells, thus avoiding the generation of spontaneous combustion.
