The lifespan of lithium iron phosphate batteries is generally around 8 years.
Lithium iron phosphate battery is a lithium ion battery that uses lithium iron phosphate as the cathode material. It has the characteristics of high safety and stability, high temperature resistance and good cycle performance. According to calculations, its lifespan can reach more than 2,000 times, but we generally calculate the lifespan at 80%, which is about 1,600 times, and the attenuation rate is about 5%.
Just like the ternary lithium battery, the theoretical life of the lithium iron phosphate battery also exceeds 2,000 charge and discharge cycles. Even if it is charged every three days for daily home use, it can still be used. about eight years. In the south, lithium iron phosphate batteries have a relatively longer lifespanlong, although their capacity will be reduced by approximately 10 to 30% at low temperatures. The charge and discharge cycle life of lithium iron phosphate batteries can generally reach more than 2,000 times, which is enough to support up to 140,000 kilometers of pure electric driving.
Generally, the lifespan of lithium iron phosphate batteries is about 8 years, but the specific years depend on various factors, including battery manufacturing and material quality, current and charge and discharge voltage, ambient use. temperature, etc. In actual use, it must be evaluated and managed according to specific circumstances.
Advantages and disadvantages of lithium iron phosphate batteries
1. Advantages: High safety and stability, high temperature resistance, environmental protection and longevity are the advantages of Bed Batterieshium iron phosphate. Compared with ternary lithium materials that deflagrate when confronted with high temperatures of more than 300 degrees, lithium iron phosphate batteries will not explode and burn even if short circuited. Therefore, in terms of safety performance, lithium iron. Phosphate batteries are deeper than ternary lithium batteries. First, this is why most new energy buses use lithium iron phosphate batteries.
2. Disadvantages: The disadvantages of lithium iron phosphate batteries are also very obvious. They are large, so they take up more space in domestic new energy vehicles. Lithium iron phosphate batteries that focus on high temperature resistance have poor low temperature discharge performance, which is very different from ternary lithium batteries. Andenergy density is low. Every time it reaches 150wh/kg, the volume/weight of the battery will be larger.
