Electric car batteries are the source of power on an electric car, there are many types of batteries, the common types on the market today are lead-acid batteries and lithium batteries, but there are also other types of batteries.
Lead-acid batteries are widely used in various electric vehicles in various countries due to the combined factors of cheap price, abundant material sources, higher power, more mature technology and manufacturing process, and high resource recovery rate. However, lead-acid batteries are usually heavy, and if charging is insufficient for a long period of time, it will cause the crystallization of lead sulfate, make the pole plate sulfurized, and the quality of the battery will be deteriorated; on the contrary, if the battery is over-charged, the amount of oxygen produced by the anode is greater than the adsorption capacity of the cathode, which will make the internal pressure of the battery increase, leading to gas spillage, electrolyte reduction, and may also lead to the activated substance softening or falling off, and the life of the battery is greatly shortened.
Lithium batteries have high capacity, small size, light weight, no memory effect, low self-discharge, can be recharged quickly, and high efficiency. It can store more energy than other types of batteries, doesn't need regular discharge to maintain its capacity, doesn't lose a lot of power in time when it is not used for a long period of time, can be recharged quickly and so on. However, lithium batteries are more expensive compared to lead-acid batteries, are more sensitive to low temperatures, and are not suitable for use in cold weather. Lunyee's electric bike batteries are mainly lithium batteries, if you need other types of batteries, we can also provide.
Of course, there are some other types of batteries on electric vehicles, such as nickel-cadmium batteries, nickel-metal hydride batteries, etc., but nickel-cadmium batteries are easy to cause toxicity when improperly disposed of, and both of them have a relatively low energy density and will quickly lose power when not in use.
Different types of batteries have different advantages and disadvantages, but whichever type you choose, you need to make sure it is compatible with your vehicle.
