The advantages of lithium iron phosphate batteries and ternary lithium batteries

How many years can the lithium battery of a pure electric vehicle last? Are lithium batteries expensive? Regarding new energy vehicles, battery life is divided into cycle life and service life. The power lithium-ion batteries currently used in automobiles are roughly divided into various batteries such as lead-acid batteries, lithium batteries, and nickel-hydrogen batteries, as well as ternary lithium batteries and lithium iron phosphate batteries with the most complicated applications. Lithium iron phosphate batteries and ternary lithium batteries also have their own advantages. The theoretical cycle life of a ternary lithium battery is about 1500 times. In practical applications, it has a complete charge and discharge cycle of more than 800 times. When the battery is discharged 25%-75%, it can be used more than 1200 times. Compared with ordinary lithium battery electric vehicles, 200 kilometers of cruising range, a complete cycle can actually travel 180 kilometers, 800 cycles can travel 144,000 kilometers, including normal attenuation, 120,000 kilometers is also stress-free. The charge-discharge cycle life of lithium iron phosphate batteries can generally reach 2000 times, and even a car with a lifetime of only 70 kilometers can support 2000-cycle pure electric driving for 140,000 kilometers. The only disadvantage is that low energy density and low attenuation are very important. ℃ capacity will be reduced by about 10%, capacity will be reduced by about 30%-20 degrees. In addition to the charge-discharge cycle of the battery itself, the storage life is also an important factor to measure the function of the secondary battery. As the saying goes, the car is not afraid, afraid you will not open, new energy vehicles, this car is equivalent to reducing the use of life, but now the blue treasure, lithium iron phosphate batteries and ternary lithium batteries can be used in humid places. Up to more than 10 years. According to industry sources, the battery replacement price of BYD's Tang and Song series is about 50,000 yuan, and if it is out of warranty, there will be labor costs and disassembly when replacing the battery. For example, Tesla, the battery price is only about 210,000 yuan. If Tesla’s battery replacement price is about 350,000, plus tariffs from abroad to my country, the conclusion Lampl said that with the maturity of all-electric vehicles, the cost of battery replacement may be reduced, but all of this is unclear. This is why more and more people are still buying all-electric cars instead of gasoline-powered cars.
