Lithium batteries may spontaneously ignite if they are left at home without charging. The reason for this is that the causes of spontaneous combustion of lithium batteries are not only charging, but also internal failures, aging, and impurities in the electrolyte. It can be seen that even if the lithium battery is not charged at home, it cannot avoid spontaneous combustion.
  Lithium battery consists of four parts, namely positive electrode, electrolyte, separator and negative electrode. Among them, whether there are impurities in the electrolyte, whether the separator can function, whether there is a short circuit in the circuit, etc. may affect the stability of the lithium battery. Once there is a problem inside the lithium battery, such as short circuit, diaphragm damage, electrolyte contamination, etc., it is easy to cause the lithium battery to generate heat out of control, and then cause spontaneous combustion and explosion.


  The role of lithium batteries: it can inhibit the polarization of the battery, reduce the thermal effect, and increase the rate performance. Significantly reduces the dynamic internal resistance increase in the cycle process; improves the adhesion between the active material and the current collector, reduces the manufacturing cost of the pole piece; improves the high and low temperature performance of the lithium iron phosphate battery, and improves the processing of lithium iron phosphate and lithium titanate materials performance.
  The service life of lithium batteries is only two to three years, and lithium batteries can generally be charged and discharged 300-500 times. It is better to partially discharge the lithium battery, rather than fully discharge, and try to avoid frequent full discharge. Once the battery comes off the production line, the clock starts ticking. Regardless of whether you use it or not, the service life of lithium batteries is only two to three years.
