Lithium iron phosphate batteries have a relatively longer lifespan.
1. Lithium iron phosphate batteries are used in normal temperature environments and charged and discharged with low currents. In this case, they are mainly used in 3C electronic products. In this field, lithium iron phosphate batteries are used. In normal use, if the battery brand manufacturer is relatively strong and of good quality, its service life will basically be more than 2,000 times; for small lithium battery manufacturers, even low-quality ones can have a lifespan of more than 2,000 times; 1000 times;
2. The theoretical life of the ternary lithium battery is about 800 cycles, which is average among commercial rechargeable lithium batteries, however, if discharged with high current for a long time or oftent. loses power, the battery life will be It is believed that the rated capacity at the end of the battery life is 70% based on the actual situation, according to the technical level of lithium batteries ternary, the capacity density of power batteries; commonly used in electric vehicles is 260 Wh/kg. According to this energy density calculation, based on 20,000 kilometers per year, based on shallow charging and shallow discharging, the service life is at least 1,000 times. If used properly, it can be used in electric vehicles for about 5-8 years.
Actual life of lithium iron phosphate batteries
The low temperature performance of lithium iron phosphate batteries is poor. The life of a single lithium iron phosphate battery is long, about 2,000 times, but the life of a lithium iron phosphate battery is short, usuallyaly about 500 times.
Lithium iron phosphate batteries have poor electrical conductivity and slow diffusion of lithium ions. When charged and discharged at high times, the actual specific capacity is low.
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as the positive electrode material.
The lifespan of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the lifespan of lithium iron phosphate batteries reaches more than 2,000 times when used with standard batteries. When charging (5 hours rate), it can reach 2000 times.
The P-O bond in lithium iron phosphate crystal is stable and not easy to decompose, even at high temperatures or overload, it will not collapse and generate heat nor will it form oxidizing substances fortes such as lithium and cobalt oxide. good security.
It has been reported that in actual operation, a small number of samples burned during acupuncture or short circuit experiments, but there were no explosion incidents in the experience of overcharging, a battery that has far exceeded. its own discharge voltage has been used several times. After high voltage charging, it was found that there was still an explosion. Despite this, its overcharge safety has been significantly improved compared to ordinary liquid electrolyte, lithium and cobalt oxide batteries.
Reference materials:
Actual battery life is approximately 3,000 charge and discharge cycles.
The lifespan of lithium iron phosphate batteries is mainlyaffected by the manufacturer's manufacturing technology, battery management technology, external environment, The influence of factors such as the car owner's driving habits and charging methods. The theoretical value of laboratory charge and discharge cycles can reach 6000 times, but the number of charge and discharge cycles when the battery attenuation is less than 20% is only 3000 times.
If the age and lifespan are calculated based on charging once a day, it can last more than five years; if daily household usage is billed every three days, it can last about eight years.
