5,000 times.
The lifespan of lithium iron phosphate battery is 5,000 times. The battery is produced with its own number of discharge cycles (eg thousand times if the number of charges and). Discharges exceed this number, the battery will expire, full discharge will seriously affect the battery usage, so do not discharge too much.
Will lithium iron phosphate be damaged when discharged to 0 volts?
Hello, I am very happy to answer your questions about why 32650 lithium iron phosphate battery cannot hold electricity. Answer: 32650 phosphate The details of the lithium iron battery's inability to store electricity are as follows: 1. The lithium ion battery is in an over-discharge state, which means that the lithium ion battery is discharged very weakly and is in a deep discharge state, energy is essentialment exhausted, so that it reaches the cut-off point of the lithium-ion battery, an activation method can be adopted at this time, but this is not necessarily effective. 2. If there is a problem with the charger or charging line, you should first check whether there is a problem with the charger. The method is very simple. Just measure the output voltage directly or connect a load with the corresponding voltage to observe it. If there is a problem with the line, then you will have to make some effort. After all, it involves circuit hardware and other issues. If necessary, disassemble it immediately. 3. After prolonged use of a lithium-ion battery, the possibility of battery failure is relatively small, but it cannot be ruled out. You should familiarize yourself with your own battery and replace it after how long it has been used. . 4. There is a problem with the battery charging ICttery or the BMS system. The battery management system exhibits problems due to reasons such as cell imbalance, resulting in misjudgment by the management IC and inability to test voltage or current.
Lithium iron phosphate will decompose when discharged to 0 volts. Overcharging and overdischarging will damage lithium iron phosphate batteries, causing irreversible damage to the battery. Overcharging will cause lithium dendrites and overdischarging will cause copper dendrites, both of which will cause short circuits, malfunctions and other problems in lithium batteries.
Therefore, lithium batteries require shallow charging and discharging. At present, when using lithium iron phosphate batteries, protection circuits must be instwent as far as possible to ensure safety. At the same time, lithium iron phosphate battery is a relatively safe type of lithium battery.
Performance of lithium iron phosphate:
1. High energy density
The theoretical specific capacity is 170 mAh/g, and the actual product capacity The specific capacity can exceed 140 mAh/g (0.2C, 25°C).
2. Safety
It is the safest lithium-ion battery cathode material; it does not contain any heavy metal elements harmful to the human body.
3. Long lifespan
Under 100% DOD conditions, it can be charged and discharged more than 2,000 times. Lithium iron phosphate has good lattice stability, and the insertion and extraction of lithium ions has little impact on the lattice, so it has good reversibility. The disadvantage is that the electrode has poor ionic conductivity and is not suitable for charging and ddischarge significant currents, which hampers its application. Solution: Coat the surface of the electrode with a conductive material and a doping agent to change the electrode.sex.
The lifespan of lithium iron phosphate batteries is closely related to its operating temperature. If the operating temperature is too low or too high, it will cause great hidden dangers in the processes of charging, discharge and use.
Especially when used in electric vehicles in northern China, lithium iron phosphate batteries cannot provide normal power or the power supply is too low in autumn and winter. winter, and the temperature of the working environment must be adjusted to maintain its performance. . Domestic solutions to the constant temperature working environment of lithium iron phosphate batteries must consider the constraints of espace. The most common solution is to use airgel felt as an insulation layer.
4. Charging performance
Lithium batteries with lithium iron phosphate cathode material can be charged at a high rate, and the battery can be fully charged in just 1 hour.
