Which lithium-ion battery or lead-acid battery has a longer life?

People are born, old, sick, and die. Lithium batteries have production, use, decay and waste. Lithium batteries cannot be used again and have to be scrapped. People call this phenomenon the life of lithium batteries. Generally speaking, the battery life of a ternary lithium battery car reaches 6 years, and the battery life of a lithium iron phosphate battery car reaches 7 years is no problem. Lithium batteries are more than 3 times higher than lead-acid batteries in terms of volume ratio energy or weight ratio energy. Lithium batteries are smaller and lighter. Long cycle life. The cycle life of lithium batteries used in electric vehicles is generally more than 800 times, and lithium batteries using lithium iron phosphate cathode materials can reach about 2000 times, which is 1.5 to 5 times higher than that of lead-acid batteries. This greatly reduces the use cost of lithium batteries, prolongs the service life, and improves the ease of use. What is the life span of a lithium battery? Lithium battery life is not calculated in years, but in cycles. Regardless of whether you use it or not, the service life of lithium batteries is only two to three years. Lithium batteries can generally be charged and discharged 300-500 times. It is best to discharge the lithium battery partially rather than completely, and try to prevent frequent complete discharge. Once the battery is off the processing line, the clock starts to move. Regarding battery life, the service life of lithium batteries on ordinary electronic products is about 5 to 20 years, with an average of 8 years. However, with the current level of technology, the service life of lithium batteries in electric vehicles is only about 3-5 years. The cycle number of ternary lithium is about 500 to 1000 times, and that of lithium iron phosphate battery is about 2000 times. The life of a lithium battery is generally 300 to 500 charging cycles. Assuming that the power supplied by a complete discharge is Q, if the reduction in power after each charging cycle is not considered, the lithium battery can supply or supplement 300Q-500Q of power in total during its life. From this we know that if you charge 1/2 each time, you can charge 600-1000 times; if you charge 1/3 each time, you can charge 900-1500 times. By analogy, if it is charged randomly, the number of times is uncertain. In short, no matter how it is charged, it is constant to add a total of 300Q to 500Q of power. How long is the service life of lead-acid batteries? In recent years, lead-acid batteries have been used more and more, not only limited to the use in factories, but now people’s daily lives are becoming more and more dependent on them. Although the manufacturing technology and manufacturing process of lead-acid batteries have been improved in recent years, there are still troublesome problems in the process of continuous use. That is, the service life of lead-acid batteries always seems to be unsatisfactory. On the one hand, the service life of lead-acid batteries is not up to standard, and its service life is shortened very quickly. The domestic single 12V lead-acid battery is designed to have a floating charge life of 5-8 years, but it has been completely scrapped in 1-2 years; no matter any lead-acid battery (including domestic and imported), there is always the vicious circle of early scrapping in use. Generally, the recyclable life of lead-acid batteries is up to one and a half years, and lead-acid batteries of better quality can even be recycled for up to two years. But under normal circumstances, the life of lead-acid batteries begins to decline after half a year of use.
