JAC Motors recently made a big news, they launched the world's first sodium-ion battery production car officially off the assembly line!Mass deliveries of this new car will begin in January 2024, and that sounds amazing, right?What's even better is that this car uses the sodium-ion cylindrical battery of Zhongke Haina Company, coupled with the honeycomb battery structure independently developed by JAC, and it has achieved "never spontaneous combustion"!
This is not bragging, there are pictures and truths, this car is named "Flower Fairy", and it makes people like it when they look at it. However, some people questioned that this description of "never spontaneous combustion" is a bit exaggerated, like an advertisement. In fact, the internal structural stability of sodium-ion batteries is indeed very high, and this cathode material is stable without phase change, and the volume change rate is only 2%. Moreover, the internal resistance of sodium-ion batteries is higher than that of lithium-ion batteries, but the power is only tens to hundredths of lithium-ion batteries. So, the heat of the sodium-ion battery is low in the short-circuit state, and the temperature will not be very high.
In addition to high safety performance, sodium-ion batteries also have a big advantage: strong low-temperature performance!This kind of battery can maintain a discharge retention rate of more than 90% in an environment of minus 20, which is especially suitable for new energy vehicles in cold areas.
However, nothing can be perfect, and sodium-ion batteries also have their disadvantages and absolute advantages. To put it simply:
Lower manufacturing costs.
The energy density is very low
Now there are two mainstream types of power batteries: ternary lithium batteries and lithium iron phosphate batteries. Lithium iron phosphate batteries are widely used because of their low manufacturing cost, poor low-temperature performance and low energy density. The manufacturing cost of sodium-ion batteries is lower than that of lithium iron phosphate batteries, but the energy density is also lower.
So, the biggest advantage of sodium-ion batteries is the low cost!As long as the car equipped with this battery can be cheaper, or the current use of lithium iron phosphate or ternary lithium battery car ** is further reduced, the value of this power battery can be reflected.
In 2023, Chery is the first brand to apply for a car equipped with sodium-ion batteries, but there is no news of mass production and delivery yet. JAC Motors took the lead in bringing mass production vehicles off the assembly line and applying them this time. As long as the sodium-ion battery version of the JAC Flower Fairy can reflect the advantages of the car, or achieve an increase in mileage on the basis of the same, JAC Motors may break the small and micro car market lineup of the five major brands of Wuling, Chery, Geely, Changan and BYD.
However, if the vehicle's **, battery life, and configuration are all unchanged, but the type of power battery has been adjusted, then the result can be imagined. Therefore, it is indeed worthy of recognition that these two car companies in Anhui took the lead in applying sodium-ion batteries, but they also have to reflect the value of this battery through vehicles.
What do you think of this innovation of JAC?Do you think sodium-ion batteries will become the development trend of new energy vehicles in the future?Welcome to leave a message to discuss!
