At present, lithium batteries are still irreplaceable in the new energy automobile industry. Although they have some shortcomings, such as spontaneous combustion and poor low-temperature stability, these risks are avoided to some extent due to the control of technology by major automakers, such as BYD's blade battery and the industry-first direct cooling and direct heating technology for battery packs, Guangzhou Automobile Aian's magazine battery and the fifth-generation intelligent temperature control system.
However, it is worth mentioning that because lithium batteries contain rare metals such as lithium cobaltate and nickel, their costs are generally high, which is why new energy vehicles are more expensive than fuel vehicles.
Then the question is, is it possible to reduce the price of lithium ore in the future, or to produce a new battery to replace lithium batteries, thus reducing the price of new energy vehicles?
Extracting lithium from seawater to reduce costs? The sodium ion battery has been successfully loaded.
At present, it is known that Contemporary Amp Technology Co., Ltd. will control the cost of battery-grade lithium phosphate at 200,000 yuan/ton through "lithium mine rebate", but even so, the price is still very high. However, as of March 8th this year, the world's first seawater lithium extraction project landed in Qingdao, Shandong, China, and the cost of battery-grade lithium phosphate has been well controlled at 35,000 ~ 50,000 yuan/ton, which shows that the cost of new energy vehicles will be lower and lower in the future.
Moreover, in addition to reducing the cost of lithium by extracting lithium from seawater, experts have also found a "substitute" for the battery itself!
This is a sodium ion battery. Compared with lithium batteries, sodium ion batteries are richer in resources, and the mining cost is only 1% of lithium. Because of the characteristics of sodium salt, it allows the use of low concentration electrolyte, and sodium ions do not form alloys with aluminum. The negative electrode can use aluminum foil as the current collector, which can reduce the cost and weight of the battery. It is reported that the cost of domestic high-capacity sodium battery materials is only 50,000-60,000 yuan/ton.
In addition, it charges faster. It is reported that Sihao New Energy has successfully built the first sodium ion battery test vehicle, which is mounted on its own product Flower Fairy, with a battery capacity of 25KWh and a fast charging time of 15 ~ 20 minutes. In addition, it is more resistant to low temperature and high temperature. Even at the low temperature of -40 degrees Celsius, the capacity retention rate of sodium ion battery is as high as 70%, and it can be recycled at the high temperature of 80 degrees Celsius. It can be seen that the stability of sodium battery is higher. So, will new energy vehicles become cheaper and cheaper in the future?
Lower battery cost? The cost of building a car will be relatively reduced.
Take pure electric vehicle as an example, the cost of battery pack accounts for about 10% ~ 40% of the whole vehicle price. Taking a 300,000-yuan pure electric vehicle as an example, the cost of battery pack is about 30,000 ~10.2 million yuan. The decline in battery cost means that the cost of building a car is reduced, and the price of the car will naturally come down.
In addition, the manufacturing of new energy vehicles will become more and more mature in the future. Automobile manufacturers will certainly try their best to reduce manufacturing costs and carry out modular production, and the price of cars will still fall. Among them, CEO He of Xpeng Motors also clearly stated on this month's 17 that costs will be reduced in the future, and Xpeng Motors will promote cost reduction through platform modularization and technological innovation!
As a result, the price of the car itself has dropped, and it is easier for the country to recover the benefits of new energy vehicles smoothly. Therefore, the Secretary-General of the Federation had previously? Cui Dongshu's suggestion that green brand new energy vehicles and blue brand fuel vehicles will not be treated differently is also very reasonable.
Write it at the end
Nowadays, with more and more consumers accepting new energy vehicles, coupled with the increasingly mature industry and good control of battery costs, new energy vehicles will become cheaper and cheaper in the future!
