What is the difference between lead-acid batteries and lithium-ion batteries?

Among them, lead-acid batteries are the cheapest, but they are large in size, heavy in weight and short in life. Lithium batteries can also be divided into two types, each with a single voltage of 3.7V and 3.2V, of which the 3.2V polymer battery is said to be safer than the other. The disadvantage of lithium batteries is that they are expensive, but they are light in weight, small in size, and have a long life (as far as I know, the life of lead-acid batteries should not be less than that of lithium batteries after daily use of the repair device). There are also capacitors for research. Its life span is relatively infinite, but even if a super capacitor with a large capacity is used, its volume and weight are several times larger than that of a lead-acid battery. I personally feel that it is basically useless. Electric vehicle batteries are divided into two categories, storage batteries and fuel power batteries. Batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-hydrogen batteries, sodium-sulfur batteries, secondary lithium batteries, and air batteries. Fuel power cells are dedicated to fuel power battery electric vehicles, including alkaline fuel power cells (AFC), phosphoric acid fuel power cells (PAFC), molten carbonate fuel power cells (MCFC), solid oxide fuel power cells (SOFC), Proton exchange membrane fuel power cell (PEMFC), straight methanol fuel power cell (DMFC). With different types of electric vehicles, there are slight differences. In a pure electric vehicle equipped with a battery only, the purpose of the battery is the only source of power for the car's drive system. In a hybrid vehicle equipped with a traditional engine (or fuel power cell) and a battery, the battery can not only play the role of an important power source for the vehicle drive system, but also act as an auxiliary power source. It can be seen that at low speed and starting, the battery plays the role of an important power source for the car drive system; when accelerating at full load, it acts as an auxiliary power source; when driving or decelerating or braking, it acts as a storage energy.
