Lead acid battery and lithium battery comparison

Usually, the lead-acid battery pack weighs 16-30 kg and has a large volume. The lithium battery generally weighs 2.5-3.0 kg and has a relatively small volume, so it is easy to ride and easy to carry. From the quality point of view, the quality of the two is difficult to define, but consumers can buy a good quality battery produced by a regular manufacturer according to their actual needs.

Lithium electricity pool of cathode materials, anode materials, collection of fluid, membrane, electrolyte, advocate material costs a lot higher than lead acid battery. The lead-acid battery assembly and auxiliary material cost is very low and the external circuit system.

Because of making craft, lithium battery of artificial cost is larger. In manufacturing costs, labor costs accounted for more than 40%, lithium-ion batteries and lead-acid battery of artificial cost is commonly 10% ~ 20%.

Lithium battery production equipment expensive, high value, mechanical equipment depreciation loss is bigger. Most of the lithium-ion batteries in the production process is irreversible, and lead-acid battery is reversible repair and used again. Lead-acid battery use after the recovery value of over 40%, and lithium battery recycling value is almost zero.

Lithium batteries are more than three times higher than lead-acid batteries, regardless of their volumetric energy or weight-to-weight energy. Lithium batteries are smaller and lighter, have a long cycle life. The cycle life of lithium batteries used in electric vehicles is generally more than 800 times. The lithium batteries using lithium iron phosphate cathode materials can reach 2000 times, which is 1.5 to 5 times higher than lead-acid batteries. This greatly reduces the cost of using the lithium battery, prolongs the service life and improves the ease of use. Has a wide range of charging power. This is a unique advantage of lithium batteries. When necessary, the charging time can be controlled from 20 min to 1 h, and the charging efficiency is over 84%. Based on further technological innovation, this feature will be better played.
