Lithium iron phosphate battery is one of the batteries with the fastest development in battery technology today. It is a new type of battery with no pollution, high capacity, high efficiency, high stability, low internal resistance and long service life. The parameters of this battery refer to the performance indicators of the battery, including voltage, capacity, energy density, charging rate, discharging rate, cycle life, etc.


  1. Voltage of lithium iron phosphate battery
    The nominal voltage of lithium iron phosphate battery is 3.2V, and the actual working voltage is generally between 2.8V and 3.6V. When in use, it is necessary to pay attention to keeping the voltage difference between the positive and negative poles within a suitable range to avoid too low or too high voltage, which will affect the performance and life of the battery.

  2. Capacity of lithium iron phosphate battery
    The capacity of a lithium iron phosphate battery generally refers to the rated capacity, that is, the electrical energy that the battery can provide from being fully charged to being completely discharged, usually in units of ampere-hours (Ah). The capacity of the battery is related to factors such as voltage and load current. Generally, when in use, charging and discharging should be carried out according to the rated capacity to achieve a longer service life.

  3. Energy density of lithium iron phosphate battery
    Energy density refers to the energy stored in a battery family member and its weight or volume. For LiFePO4 batteries, energy density is crucial because it affects the efficiency of the battery and the practicality of portable applications. Energy density is usually in units of watt-hours per kilogram (Wh/kg) or per liter (Wh/L). The power density of LiFePO4 batteries is usually between 90-140 Wh/kg and 220-300 Wh/L.


Longer run times require higher performance, and higher energy density is essential for minimizing the weight and size of mobile devices.


  1. Charging rate of lithium iron phosphate battery
    The charging rate of a lithium iron phosphate battery generally refers to the charging rate, that is, the ratio of the charging current to the rated capacity of the battery based on the rated capacity of the battery. The charging rate of this battery is generally between 0.2C and 1C, that is, charging at 0.2 to 1 times the rated capacity of the battery. Too fast charging rate will affect the life of the battery and should be avoided as much as possible.

  2. Discharging rate of lithium iron phosphate battery
    The discharging rate of a lithium iron phosphate battery generally refers to the discharging rate, that is, the ratio of the load current to the rated capacity of the battery based on the rated capacity of the battery. The discharging rate of this battery is generally between 0.2C and 3C, that is, discharging at 0.2 to 3 times the rated capacity of the battery. Too fast discharging rate will affect the performance and life of the battery and should be avoided as much as possible.

  3. Cycle life of lithium iron phosphate battery
    The cycle life of a lithium iron phosphate battery refers to how many times the battery can complete cyclic charging and discharging, generally expressed as the number of charging and discharging cycles. This battery has a long cycle life and can generally reach more than 2000 times, but the actual number of cycles will be affected by factors such as the use and maintenance of the battery.


In short, the parameters of lithium iron phosphate batteries are very stable and reliable. However, in order to achieve the best use effect, it is necessary to pay attention to factors such as voltage, capacity, charging and discharging rate when in use, and maintain a suitable working temperature and avoid polarization during charging and discharging. Only by using this battery scientifically and reasonably can its performance be fully exerted and its service life be extended.
