Most electric vehicles use lead-acid batteries, and some high-end products use lithium batteries.
Because the cost of lithium batteries is higher, electric vehicles using lithium batteries are more expensive.
Lithium batteries are lighter and have higher energy density.
The cruising range of electric vehicles mainly depends on battery capacity and motor. Generally speaking, the higher the battery capacity, the higher the cruising range.
The working principle of lithium battery is similar to that of lead-acid battery, but the anode and cathode materials of the two batteries are different.
The positive and negative electrodes of rechargeable batteries will use two metals with different active properties, which can release ions. After ions are generated, electrons will be generated inside the external circuit, so that there will be current in the external circuit.
The chemical reaction in rechargeable battery is reversible, and the direction of chemical reaction is different when charging and discharging.
With the increase of battery charge and discharge times, the storage capacity of the battery will also decrease, so the battery is a vulnerable part of electric vehicles and needs to be replaced regularly.
