Do lithium batteries really last longer than lead-acid batteries?

Lithium batteries really have a longer life than lead-acid batteries? What do you think? Long life is not long I ignore, light, lead weight is only one-third of electricity, mobile vehicles are easy enough, lithium battery, I only realize at present Lithium iron phosphate, my 2 electric bicycles, a BYD electric SUV, lithium iron phosphate batteries, lithium batteries for electric bicycles must have a protective plate, an accurate coulomb meter, and a dedicated charger. Otherwise, lithium batteries are not recommended. Note: I have a lithium battery I bought in May 2013. I will not tell you if it has a long life. Lithium batteries last longer than lead-acid batteries, but there is no definite answer yet. A genuine lithium battery used under the same conditions must have a longer life than a lead-acid battery. The most discussed are electric bicycles, mobile phones, and laptops that cannot use lead-acid batteries. A qualified electric bicycle has a speed limit. In this case, the life of a lithium battery is three to five times that of an ordinary electric bicycle. Lead-acid batteries are characterized by a large discharge current and a semi-liquid state. The parts inside the battery that are overheated and damaged by overcurrent will move, take the average value, and weaken. The discharge characteristics are oblique straight lines and the electrode contact area is large. Lithium batteries are characterized by high specific energy, light weight, and solid state. They are afraid that the electrode overload will affect the loss of carbonization and disconnection. Once damaged, the internal problems cannot be transferred, fixed, and the increase in internal resistance is irreversible, so the use of large currents is not recommended. , The electrode contact area is small, and the slope of the discharge characteristic is before the first steep level. When the electric vehicle starts, the controller limits the current to 15A, and 1C discharge of lithium batteries is not recommended. Therefore, lithium batteries larger than 15AH have a longer life. In order to pursue high speed, high efficiency and high gradeability, the starting current of non-lithium battery controllers is artificially increased, and there are many private modifications. For details, please refer to the title of the video on how to make electric vehicles run faster. Lithium acid users did not replace the lithium governor, and the protection function declined. Since the voltage platform of lithium batteries is higher than that of lead-acid, the efficiency of the first third is higher than that of lead-acid. New batteries run faster when they are just charged, and will age quickly under non-standard use. In addition, due to human factors such as unlimited speed and current limitation, carrying people, and insufficient tire air, battery electrodes and nearby storage materials will age faster. Is lithium or less energy than acid? No, the initial speed of acid charge is several kilometers slower than that of lithium charge. Uncontrolled use is to increase the service life of lithium batteries. Once the electrodes and storage materials are damaged, they will be irreversible. National standards for battery use are industry norms. Lithium batteries that exceed the limit have reached normal use, and their performance is bound to decline. It is said that lithium is inferior to acid, and there are definitely the following points: 1. There is no speed limit. 2. Existence of overload behavior. 3. The acid removes lithium without changing the governor. 4. The car is in poor condition. The tires are not often inflated and the car lacks maintenance. Normally compliant cars, there must be no such problem. My 48v20AH lithium battery, 3 years, 60 kilometers, 12AH, 2 years, 45 kilometers, is not damaged.
