Is the life span of lithium batteries really longer than that of lead-acid batteries?

The life of lithium batteries is definitely longer than that of lead-acid batteries. This is determined by the material structure used, and the principle is basically similar. Batteries are composed of a positive electrode, a negative electrode and an electrolyte, but the properties of the materials vary greatly. Lead-acid batteries are composed of lead, lead sulfate and sulfuric acid solution. With the increase of the number of charge and discharge, the reduction ability of the positive and negative materials becomes worse and worse, and the concentration of the sulfuric acid solution will also change. According to the standard of the processing technology, the battery that is cyclically charged at room temperature for more than 400 times and maintains more than 80% of the capacity is a qualified product. The lifespan of lead-acid batteries is about two years, and the number of cycles of charging and discharging is less than 300 times, while lithium batteries generally have a service life of more than 3 years, and the number of cycles of charging and discharging exceeds 500 times. But these are theories, and the actual situation depends on the user's usage. After all, reasonable protection of the battery and the correct charging method can extend the battery's life. Because the voltage platform of lithium batteries is higher than that of lead-acid, the efficiency of one-third in the past is higher than that of lead-acid. New batteries will run faster when they are charged, and will age quickly under irregular use, plus unlimited Human factors such as speed limit current, driving people, insufficient tire air, etc. make the battery electrodes and nearby storage materials age faster. The price of lithium batteries should be more expensive than batteries. In terms of safety, batteries are old and lithium batteries are relatively new, so safe storage of electricity should be better than lithium batteries.
