Recently, the hot sales of two-wheeled electric vehicles in the market have set off a "sodium electricity boom". Xinri and Emma launched a new model with polysodium batteries, and announced that their 48V24AH batteries are priced at 599 yuan.

This price is nearly 200 yuan lower than the lead-acid battery, and more than 300 yuan lower than the lithium battery, which is known as the "comprehensive hanging" of traditional lead-acid and lithium batteries. Some analysts also predict that polysodium batteries will fully replace lead-acid batteries as the mainstream power source for electric vehicles in the future.
We might as well take a deep look at whether the polysodium battery can really be as expected to set the tide in one shot?
From the point of view of technical level, polysodium batteries do show certain potential. Its claimed performance data of 90% fast charging in 10 minutes and 1,500 cycles has caught up with lead-acid batteries at the same scale, competing with lithium batteries. Moreover, after large-scale production, the cost performance of polysodium batteries still needs to be improved. However, the uncertainty in terms of safety, physical properties, cycle life, etc., cannot be ignored. It needs to be tested for a long time in actual operation whether it can be solved with technological progress.
From the cost side, although the price of 599 yuan is eye-catching, this is just an example. Just like the early lithium batteries, the cost of a single battery will further decrease with the increase of scale capacity. At the same time, there is still a lot of room for optimization of the substantial cost of polysodium batteries in raw material procurement, cell integration and power system integration. It is difficult to truly replace the cost advantages of traditional batteries in the short term.
From the perspective of market penetration, two-wheeled electric vehicles are the main target of polysodium batteries. However, lead-acid batteries have long gained a firm foothold in this market, and the supporting industries are well supported. In addition, more than 400 million electric vehicles are in use around the world, and replacing them with new battery technology will be a complex system engineering. Even if the technology is mature, it needs to be promoted for a long time before it can be mass-produced.
Netizens are hotly discussed
Netizens think: The price of 48V24AH polysodium No. 1 is 599 yuan, which is still more conscientious.
Netizen question: What is the capacity density?How many kilometers can 48V/24Ah run?Netizen replied: "The weight is less than 11kg, and the energy density of a single cell is 122Wh/kg." ”
Netizens said: It is as easy as a lithium battery to catch fire, which is unbearable.
Netizens said: As long as the price is the quality of the product, it is really so good, and it is only a matter of time before it replaces lead-acid. The actual price of lithium batteries used in electric vehicles is almost five times more than that of lithium batteries for automobiles.
Netizens said: Cars using lead-acid batteries cannot directly replace sodium batteries, which directly limits the promotion of sodium batteries.
Write at the end
Overall, polysodium batteries are indeed very competitive in the market as a new technology. However, under the current conditions, it is still difficult to completely replace lead-acid and lithium batteries. In the short term, the coexistence of the two seems to be an inevitable choice.
Only through continuous technological breakthroughs to reduce costs and increase efficiency, form a mature industrial ecology, and verify its reliability in practice, can polysodium batteries be expected to truly "beat" traditional batteries in specific application fields in a long history and become the preferred technology. We also need to follow up and support us consistently.
