How many types of batteries are there? Points to know about new energy sources

With the continuous development of new energy vehicle technology, the capacity of batteries for storing electricity is expanding in order to improve battery life. So, what are the types of power batteries that are so important? What is the difference? Take a look at the new energy's important component - battery.

According to the classification of battery materials,lithium battery cell machine there are currently four main categories of new energy vehicle batteries:.

Lead-acid batteries

Perhaps many people do not know that lead-acid batteries are the most successful technology that people have mastered now. As a mature technology, lead-acid batteries are still the only batteries for mass production of electric vehicles due to their low cost and high rate of discharge. It is mostly used in electric vehicles.

However, the specific energy, specific power and energy carry density of lead-acid batteries are very low,car battery manufacturers which can also lead to the enterprise using traditional lead-acid batteries for electric vehicles, the range development mileage and speed can not keep up.

Nickel batteries

Although in general, the performance, although better than lead-acid batteries, but contains heavy metals, the use of easy to cause pollution. nimh batteries have just begun to mature for hybrid battery systems.

However, because the domestic R&D of Ni-Cd batteries is not mature, domestic companies have been in the R&D stage, and the Ni-Cd and Ni-MH batteries we use are mainly purchased from abroad.

Lithium battery

As one of the mainstream of new energy batteries,battery coating lithium batteries have the advantages of light weight, long life, no pollution, small size, etc. However, one of the important reasons why the development of lithium batteries is hindered at present is the safety. Due to the high operating temperature of lithium batteries, this also puts high requirements on the safety performance of the car.

Lithium iron phosphate battery

Lithium iron phosphate battery is also a kind of lithium battery, but the energy fluctuation is only half of the lithium battery, higher safety, 2000 cycles, discharge stability, low price, and the cost performance is quite low. Now it has become one of the main factions of many electric vehicles.

Currently on the market in China's new energy models of the battery is mainly ternary lithium batteries and lithium iron phosphate batteries, battery development issues are also the key to the development of China's new energy automobile industry, the battery system capacity and charging and discharging efficiency aspects have a great degree of enhancement, however, our individualism that the battery capacity is certainly a good thing, but for everything to be established in the conditions of information security, once there is no spontaneous combustion Consequences unimaginable.
