Is it better to use lithium batteries or lead acid batteries for electric vehicles?

Whether an electric vehicle uses a lithium battery or a lead-acid battery depends on many factors. From a performance perspective, lithium batteries have higher energy density and lighter weight. Lithium batteries are more expensive and require more complex charging equipment and higher charging voltages, which increase the cost of use and difficulty of charging. Although lead-acid batteries have lower energy density and heavier weight, they are relatively inexpensive and the equipment and charging methods are relatively simple.
