The battery is one of the important parts of the electric vehicle, because the battery stores all the energy required by the electric vehicle, and drives the electric vehicle by releasing energy, in the past, lead-acid batteries and lithium batteries were mainly used, since 2023, sodium batteries have begun to be gradually widely used, and JAC's world's first sodium battery electric car has been delivered in batches, and the battery life is not reduced in winter, and the charging speed is twice as fast as that of lithium batteries, let's find out!

The application of sodium batteries is becoming more and more widespread

In the past, electric vehicles mainly used lead-acid batteries and lithium batteries, although the advantages of the two batteries are more prominent, but these two batteries also have their own disadvantages, such as lead-acid batteries are bulky, short service life, lithium battery prices are high, and there are safety risks.

Battery manufacturers have been developing new batteries, and sodium batteries have gradually gained a wide range of applications since 2023, and in 2023, electric vehicle brands such as Yadea, Xinri, and Tailing have successively released sodium battery versions of two-wheeled electric vehicles, and a number of sodium battery production bases have also begun to be built.

The first sodium battery car was delivered in batches, and the battery life in winter was not reduced, and the charging speed was 1 times faster than that of lithium batteries

In addition to the use of sodium batteries for two-wheeled electric vehicles, if new energy vehicles can be equipped with sodium batteries, it is believed that the cost will be greatly reduced, JAC's world's first sodium battery new energy vehicles are delivered in batches, the vehicle is equipped with sodium batteries, which has the advantages of not reducing the battery life in winter, and the charging speed is twice as fast as that of lithium batteries.

The sodium electric plate flower fairy model delivered this time is equipped with 32140 sodium-ion cylindrical cells supplied by Zhonghe Haina, with a honeycomb battery safety structure, the entire battery pack capacity is 23.2kwh, the cell cell capacity is 12Ah, the energy density is ≥ 140Wh/kg, and the cruising range can reach 230 kilometers.

Although the energy density is not as good as that of lithium iron phosphate batteries, it has great advantages in low-temperature performance, even in a low temperature environment of minus 20 degrees, the battery can maintain 92% of its capacity, so in extremely cold weather, the cruising range will not be reduced.

In addition, the sodium battery tram also supports fast charging function, which takes only 20 minutes from 10%~80% and only 15 minutes from 30%~80%, which is twice as fast as lithium battery.

The energy density of sodium batteries is not as good as that of lithium batteries, but the advantages are also very prominent

Although the current energy density of sodium batteries is not as good as lithium batteries, only about 80% of lithium iron phosphate batteries, but the energy density of sodium batteries is still relatively fast, with data show that in the next two years, the energy density of sodium batteries can be increased to 160~180Wh/kg, 5 years later, it can even reach 200Wh/kg, at that time it is greater than the energy density of lithium batteries.

In addition to the advantages of fast charging speed and good low-temperature performance, sodium batteries also have two outstanding advantages.

1. The sodium battery can be discharged to 0V

We know that whether it is a lead-acid battery or a lithium battery, it is impossible to discharge to zero volts in the process of use, and too low discharge will damage the battery, but sodium batteries can be completely discharged to 0V.

That is to say, even if the sodium battery is not charged, it can be used for storage and transportation in the state of 0V, so that the sodium battery is more convenient to store, and at the same time, it also improves the safety of transportation, and can also release more electrical energy during use, so that the electric vehicle can last longer.

2. Sodium batteries are rich in raw materials

Although the advantages of lithium batteries are more, 80% of the raw materials of lithium batteries depend on imports, and raw materials are scarce, resulting in the rise in the cost of lithium batteries, but sodium batteries are different, sodium batteries are rich in reserves, and widely distributed, do not need to import, if sodium batteries can be mass-produced, the price will drop significantly, and the price of electric vehicles will be reduced.

Summary:

Sodium battery is regarded as the ideal electric vehicle battery at present, not only the sodium battery version of two-wheeled electric vehicles has been released, but also the sodium battery version of new energy vehicles has been delivered in batches, indicating that the manufacturing of sodium batteries has reached an advanced level, and it is expected that in 2024, more sodium battery electric vehicles will appear to facilitate people's travel.
