Safety Features Of Lithium Iron Phosphate Batteries：

Of all types of lithium batteries, lithium iron phosphate batteries are arguably the safest. Under the same application conditions, their cathode material is not easily decomposed, oxygen evolution is not severe, and they don't generate significant internal combustion pressure in a short period of time, making them less likely to explode. At most, they will slowly begin to burn.

Under normal circumstances, lithium iron phosphate batteries will not explode. In extreme cases, battery cells typically have safety valves (cylindrical/aluminum-cased) to release pressure, while pouch cells are more likely to expand and release pressure, making them less likely to explode. Therefore, the probability of lithium iron phosphate battery explosion in extreme circumstances is very low.

Of course, there are still occasional incidents, such as violent collisions in accidents, which can lead to spontaneous combustion and explosion. However, compared to other types of lithium batteries, their performance is relatively mild, so they require a fireproof casing (iron box, aluminum shell, or fireproof plastic shell), a reliable protective plate, and fireproof materials to secure the internal wiring harness and auxiliary filling materials.

Use a reliable, dedicated charger. The lithium iron phosphate batteries we use are generally not single cells, but rather battery packs that meet application requirements through wiring and a battery protection board. This means that the voltage, cell capacity, and pack discharge capacity must meet application requirements. The battery charger must ensure that the charging voltage and current can be detected and controlled during charging to balance voltage and capacity variations between cells within the pack, and to control temperature to ensure safe charging.

However, as demonstrated by cycle testing at 45°C or 60°C, the cycle life of lithium iron phosphate batteries at high temperatures is generally proportional to their safety (batteries with longer life at high temperatures typically have materials and designs that enhance safety). Of course, the quality of lithium iron phosphate battery cells varies, and the resulting battery packs naturally vary as well. The difference in this metric can be several times greater.
