The lifespan of used lithium iron phosphate batteries mainly depends on the duration of use. First, they have a lifespan of over 2,000 times. With a standard charge (5 hour rate). can reach 2,000 times.
Used under the same conditions, the theoretical lifespan of lithium iron phosphate batteries will reach 7 to 8 years. Overall, the performance-price ratio is theoretically more than 4 times higher than that of lead-acid batteries.
High current discharge can charge and discharge quickly at a high current of 2C. With a special charger, the battery can be fully charged in 40 minutes at 1.5C, and the starting current can reach 2C, while the battery can be fully charged in 40 minutes at 1.5C. lead acid batteries do not have these performances.
The lithium iron phosphate battery is a lithium-ion battery that uses lithium ironphosphate (LiFePO4) as positive electrode material and carbon as negative electrode material. The nominal voltage of the single cell is 3.2. V, and the charging cut-off voltage is 3.6V ~ 3.65V.
During the charging process, some lithium ions present in lithium iron phosphate are released , transferred to the negative electrode through the electrolyte and integrated into the carbon material of the negative electrode at the same time; electrons are released from the positive electrode and reach the negative electrode from the external circuit, thus maintaining the balance of chemical reactions.
During the discharge process, lithium ions flow out of the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons and reaches the positive electrode of the external circuit to supply. energy to the outside world.
Lithium iron phosphate batterieshave the advantages of high operating voltage, high energy density, long service life, good safety performance, low self-discharge rate and no memory effect.
Lithium iron phosphate battery actual lifespan
Pacific Automotive Network's lithium iron phosphate battery can withstand temperatures of -20 ° to +75°. The advantages of lithium iron phosphate batteries are ultra-long life. The lifespan of ultra long life lead acid batteries is about 300 times, up to about 500 times the lifespan of lithium iron phosphate batteries is more than 2000 times. . Standard charge (5 hour rate), which can reach 2000 times.
The advantage of lithium iron phosphate batteries is: how many degrees can the maximum electric heat of lithium reach? Applications of lithium iron phosphate batteries With the rapid development ofmobile electronic devices and the increasing demand for energy, the demand for lithium iron phosphate batteries is also increasing. Lithium iron phosphate batteries have become an important development direction for lithium ion batteries because of their safety and stability.
The advantages of lithium iron phosphate batteries are an ultra-long lifespan. The lifespan of ultra long life lead acid batteries is approximately 300 times, up to approximately 500 times that of lithium iron. Phosphate batteries are more than 2,000 times. With a standard charge (5 hour rate), they can reach 2000 times.
2. Use safe lithium iron phosphate ion batteries to completely resolve the safety risks of lithium cobalt oxide and lithium manganate. Lithium cobalt oxide and lithium manganate can explode in violent collisions, threatening the lives of consumers. and the plithium iron phosphate, which have undergone rigorous safety testing and will not explode even in the worst road accidents.
3. High temperature resistance. Thermal peaks of lithium iron phosphate batteriesIt can reach 350°C to 500°C, while the thermal peak of lithium-manganese and lithium-cobalt is only about 200°C. Wide operating temperature range (-20°C to +75°C).
4. Light. A lithium iron phosphate battery of the same capacity is two-thirds the volume and one-third the weight of a lead-acid battery.
5. Big capacity. Has a greater capacity than ordinary batteries (lead-acid, etc.). 5ah-1000ah (single unit).
No memory effect. Rechargeable batteries typically operate at full capacity and quickly fall below their rated capacity. This is called the memory effect. Nickel-metal hydride batteries and nickel-cadmium batteries havememory, but lithium iron phosphate batteries do not have this phenomenon. Regardless of the battery's condition, it can be charged and used at any time without needing to turn it off before charging.
7. Environmentally friendly and green, lithium iron phosphate batteries are generally considered free of heavy and rare metals (nickel metal hydride batteries require rare metals), non-toxic (certified by SGS), and non-toxic. polluting, compliant with RoHS regulations in Europe, absolutely green and environmentally friendly battery.
Lithium-ion battery. Disadvantages of JPG lithium iron phosphate battery, such as poor low temperature performance, the cathode material has low vibration density, and the volume of lithium iron phosphate battery is the same as that of lithium iron phosphate battery. lithium-cobalt and other lithium-ion batteries. , there is therefore no advancetage in the micro-battery. When lithium iron phosphate batteries are used in power lithium batteries, like other batteries, they need to face the problem of battery consistency.

This type of battery has a lifespan of 7 to 8 years .
The actual life of lithium iron phosphate batteries is affected by many factors, including manufacturing process, usage environment, driving habits of car owners and loading methods. Under ideal circumstances, the lifespan of lithium iron phosphate batteries can reach more than 2,000 times. Some high-performance batteries, such as BYD's blade batteries, can have a lifespan of 8 years or 1.2 million kilometers under normal use.
The lifespan ofthe battery will be reduced due to various factors. In order to prolong the life of the lithium iron phosphate battery, car owners should maintain good driving habits and charging methods, and use the battery under appropriate conditions. terms.
