Due to the continuous research and development of new energy vehicle technology, there are different types of automotive batteries on the market.
The most important thing of electric vehicle is the endurance and power, which mainly depends on the battery of electric vehicle.
Lead acid battery
Advantages: it is also a mature electric vehicle battery with good reliability, easy access to raw materials and low price; its power can basically meet the power requirements of electric vehicles.
Cost effective, is a more popular battery.
Disadvantages: first, the specific energy is low, the mass and volume are too large, and the driving mileage of one charging is short; the other is short service life.
Lithium ion battery
Lithium ion battery cathode materials mainly include lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials and lithium iron phosphate.
Light weight, large energy storage, no pollution, no memory effect, long service life.
In the case of the same volume and weight, the storage capacity of lithium battery is 1.6 times of that of Ni MH battery and 4 times of that of Ni Cd battery.
Moreover, only 20% - 30% of its theoretical power has been developed and utilized by human beings. The development prospect is very bright. At the same time, it is a real green battery, which will not pollute the environment.
It is the best battery that can be applied to electric vehicles. The disadvantage of lithium batteries is that they are less stable and more likely to explode in hot weather.
Lithium cobalt oxide battery
Lithium cobalt oxide battery is a common battery in electronic products. It is often used as a battery cell in notebook computer.
Advantages: mature production technology, high energy ratio, about twice the energy ratio of LiFePO4 battery.
Disadvantages: at high temperature, the stability is slightly worse than that of nickel cobalt manganese oxide lithium battery and lithium iron phosphate battery.
