Who is better between lithium ion batteries and lead-acid batteries?

1. In terms of performance: lead-acid is heavy and bulky. The weight of the same battery is 3 times that of lithium-ion batteries, and the volume is twice that of lithium-ion batteries. Therefore, electric vehicles based on lead-acid are very heavy, which is also its drawback. . Therefore, many people now change lead-acid batteries to lithium-ion batteries, so that two lithium-ion batteries can be placed on the original battery tank, and the travel distance and speed have been doubled. Moreover, the acceleration of lithium-ion batteries is of great help for some jobs that are in a hurry, such as express delivery and takeaway. 2. Service life: Even the best battery has a short service life, its cost performance is also very low. The lifespan of lead-acid batteries is about 2 years. If improperly recharged, the life will be a little over a year, and the power will decrease; while the lifespan of lithium-ion batteries will only decrease after 5 years. 3. Endurance range/battery capacity: The same 48V battery. Under the fully charged condition, the range of lead-acid and lithium-ion battery electric vehicles is similar, depending on factors such as speed and motor size. Of course, lead-acid batteries will be slightly larger than lithium-ion batteries in terms of battery capacity. 4. Weight energy density: The current energy density of lithium ion batteries is generally 200~260wh/g, and lead acid is generally 50~70wh/g. Then the weight energy density of lithium ion batteries is 3~5 times that of lead acid, which means With the same capacity, lead-acid batteries are 3 to 5 times that of lithium-ion batteries, so lithium-ion batteries have an absolute advantage in lightening energy storage devices.
