Comparison of the advantages of lithium-ion batteries and lead-acid batteries

1. Comparison of the advantages of lithium-ion batteries and lead-acid batteries: a. The advantages of lead-acid batteries: low price, at the same time it comes with recyclable properties. After it is worn out, you can go to the electric car shop to replace the old with the new one, and you can change the price. It is a great benefit for users to set up new batteries to minimize the loss. Lead-acid batteries have strong anti-attack ability and can continue to be used even if they are broken and repaired a little bit. Lead-acid batteries b, the advantages of lithium-ion batteries: lithium-ion batteries have high energy density, small size, and light weight. Compared with lead-acid batteries, the volume of lithium-ion batteries is 2/3 of the volume of lead-acid batteries, and the weight is about lead-acid batteries. The weight of the battery is 1/3, and the number of cycles of charging and discharging of lithium-ion batteries is more. The durability of lithium-ion batteries is stronger than that of lead-acid batteries. The lithium-ion batteries can be continuously charged for 48 hours at room temperature without battery swelling, leakage, rupture, etc. In the event of an accident, the capacity remains above 95%, and with a dedicated charger, fast charge and discharge can be carried out, deep charge and deep discharge more than 500 times, and there is still no memory, and the general life span is basically about 4 to 5 years. 2. Comparison of the shortcomings of lithium-ion batteries and lead-acid batteries: a. The shortcomings of lead-acid batteries: firstly, the volume and weight of lead-acid batteries are very large, and the weight is generally 16-30kg, followed by lead-acid batteries under normal circumstances. Charge and discharge within 400 times, there is memory, and the service life is about 2 years (in most cases within 1.5 years), and the lead-acid battery contains liquid. After the battery is consumed for a period of time, if the battery is found to be very hot or recharged When the time becomes shorter, you must replenish the fluid. b. Disadvantages of lithium-ion batteries: the production cost of lithium-ion batteries is high, and the expensive production equipment and labor costs account for about 40% of the production cost, and the price is about three times that of lead-acid batteries. Moreover, the recycling value of lithium-ion batteries is not high, and the domestic recycling environment is rather chaotic. Most of the lithium-ion batteries can only be thrown away or buried somewhere, while inferior lithium-ion batteries are sealed in electric vehicles. The conditions are not very good, and it is easy to cause possible safety hazards due to poor contact and other reasons due to humidity.
