Which Is Better, Lead-acid Batteries Or Lithium Batteries For Electric Vehicles?

- May 23, 2020-

Disadvantages of lead-acid batteries: large volume and weight, limited battery capacity, and short life. Lead-acid batteries are generally discharged within 400 times of deep charge and deep discharge, and the life span is about two to three years. At the same time, the heavy metals produced easily cause environmental pollution.

Compared with lead-acid batteries, the volume of lithium batteries is 2/3 of the volume of lead-acid batteries and the weight is about 1/3 of the weight of lead-acid batteries. Lithium batteries of the same volume have a higher capacity than lead-acid batteries, and are more convenient to carry. Most of them can be extracted and charged. The average life of a lithium battery is about 4 years, which is about 1.5 times longer than that of a lead-acid battery. It is charged and discharged more than 500 times, and some can even exceed 1500 times. The battery has no memory and has strong shock resistance. At the same time, lithium batteries have less environmental pollution than lead-acid batteries, do not contain any heavy metals and rare metals, are non-toxic, no pollution in production and use, and comply with European RoHS regulations. Pollution, more environmentally friendly.
