Guide to the use of electric vehicles in winter, how to make lithium-ion batteries active?

Image
With the transformation of automobile electrification, consumers' acceptance of pure electric vehicles has gradually increased, and pure electric vehicles on the market have become more and more popular, but at the same time, the shortcomings of pure electric vehicles have also been exposed. Nowadays, spontaneous combustion incidents of pure electric vehicles are frequent, and even if the technology is constantly updated and iterated, it is still difficult to stop. In addition to safety issues, battery life and charging issues are also the biggest headaches for car owners. Especially in the low temperature conditions in winter, the battery performance decreases, the battery life decreases significantly, and the charging speed becomes slower, which makes many car owners a headache. So how can the problems encountered by pure electric vehicles in winter be improved? At present, the common power batteries on the market mainly include ternary lithium batteries and lit...

In 2021, the cost of battery cells will rise by more than 60%, and the overall price increase of the battery industry is imperative

Image
China's leading battery companies have recently notified contracted customers to renegotiate prices, and their quotations may increase by about 20%. It is understood that the domestic battery industry will basically raise prices in a unified manner in the near future. The long-term contract signing method is still under negotiation with downstream companies next year. It can also be seen that the willingness of battery companies to increase prices this time is firm. The collective price increase behavior of battery companies is also expected. Since the beginning of this year, lithium battery materials have increased substantially. For example, the price of battery-grade lithium carbonate has risen from an average price of 63,000 yuan/ton in January to more than 200,000 yuan in the near future, and the price has risen by 228%! The price of lithium hexafluorophosphate rose from 110,000 yuan/ton at the beginning of the year to 560,000 yuan/ton, an increase of more than...

CATL announces sodium ion battery technology! Can charge 80% in 15 minutes, dangerous for fuel vehicles

Image
Buying a fuel car or an electric car is a choice faced by many consumers. There are many reasons for choosing electric vehicles, but I believe that friends who choose fuel vehicles have two very important reasons: one is that fuel vehicles will not have the problem of mileage anxiety; the other is that the time cost of waiting for refueling is very low. In fact, the battery life of electric vehicles is not an important issue at this stage. After all, basically electric vehicles can exceed the 500-kilometer endurance mark. What's more, electric vehicles with an endurance of more than 1,000 kilometers have been released. The biggest problem at present is actually the charging problem of electric vehicles. Compared with the time required for refueling of traditional fuel vehicles, the charging speed of electric vehicles is still too time-consuming. This is also the most concerned issue for many consumers who need to travel long distances. However, for the problem of cha...

The world's first aluminum-ion solid-state battery is mass-produced, which is half cheaper than lithium batteries

Image
Saturnose, an Asian battery research and development company, announced that it will publicly release independent test results of enhanced aluminum-ion batteries, and plans to launch solid-state rechargeable aluminum-ion batteries, which will be released as soon as next year. This may be the world's first mass-produced commercial-grade aluminum-ion solid-state battery, which is expected to replace the risky lithium-ion battery. It is understood that the energy density of the aluminum ion battery is 1500Wh/L, which is expected to provide 600Wh/kg of energy. As a comparison, the energy density of lithium-ion batteries is 150-350Wh/kg, while the newly developed sodium ion of CATL is 70-200Wh/kg. The current commonly used lithium iron phosphate batteries are generally around 140Wh/kg, and some ternary lithium batteries can exceed 200Wh/kg. This means that once the aluminum-ion solid-state battery is successfully commercialized, the battery capacity can be increased by ...

Introduction of common cylindrical lithium battery models

Image
Cylindrical lithium-ion batteries are usually represented by five digits. Counting from the left, the first and second digits are the diameter of the battery, the third and fourth digits are the height of the battery, and the fifth digit represents the cylindrical shape. There are many types of cylindrical lithium batteries, the more common ones are 10400, 14500, 16340, 18650, 21700, 26650, 32650 and so on. 1. 10440 battery The 10440 battery is a lithium battery with a diameter of 10mm and a height of 44mm. The battery capacity is generally small, only a few hundred milliamperes, and is mainly used for mini electronic products. For example, flashlights, mini speakers, speakers, etc. 2.14500 battery The 14500 battery is a lithium battery with a diameter of 14mm and a height of 50mm. The voltage of this battery is generally 3.7V or 3.2V, the nominal capacity is relatively small, a little larger than the 10440 battery, generally 1600mAh, and the discharge performance is su...
