How long is the service life of lithium iron phosphate batteries?

Considering various factors, the usage characteristics of iron lithium-ion battery packs can be roughly described as follows: large volume, poor low-temperature performance, and the ability to maintain a relatively gentle decay rate during its service life, generally around 8 years; But if used in the south. The lifespan of lithium iron phosphate batteries exceeds 8 years. The service life of lithium iron phosphate battery packs is 4-5 times that of lead-acid battery packs. For lead-acid batteries with high technological content, there is no problem of reaching 5 years. Due to the collapse of the structure of the positive electrode material graphite, lithium-ion batteries will be discarded even if they are not used for five years. I believe most consumers have heard that the lifespan of lithium-ion battery packs is 500 times, and after 500 charges and discharges, the battery will die.

From this, it can be seen that if you charge 12 times each time, you can charge 600-1000 times; If you charge 13 times each time, you can charge 900-1500 times. If it is a random charge, the number of times is uncertain. In short, regardless of charging, the total power added is between 300q and 500q, which is constant. Therefore, we can also understand that the service life of lithium-ion battery packs is related to the total charging capacity of the battery, rather than the number of charges. Deep discharge and deep charging, as well as shallow discharge and shallow charging, have little impact on the lifespan of lithium batteries. In fact, shallow discharge and shallow charging are more advantageous for lithium iron phosphate batteries.
