At present, electric vehicles are a common means of transportation for people to travel. With the increasingly high national standards for environmental protection, the new national standard electric vehicles are equipped with lithium-ion batteries as power energy. Compared with other batterie...

The formation of lithium dendrite is a technical problem that cannot be avoided by the lithium battery industry at present. As long as the lithium ion battery is charged and discharged, lithium dendrite will be formed when the lithium ion is reduced. And after a long time of accumulation, when...

18650 lithium-ion battery is a common lithium-ion battery model. 18650 is the representative of size, that is, the circumference of the battery is 18mm and the length is 50mm. The 21700 lithium-ion battery is also a reason. In the application of lithium-ion batteries, the 18650 cylindrical lit...

The first is to make the electrolyte soak better, which is conducive to the stability of the performance of the lithium-ion battery pack; Second, the aging of the active substances in the positive and negative electrode materials can promote the acceleration of some side use...

There are five kinds of cathode materials: lithium cobaltate, lithium manganate, lithium nickel cobalt manganate, lithium iron phosphate, lithium nickel cobalt aluminate. The ternary cathode materials of lithium ion batteries account for a large proportion. The ternary catho...

The peak period of battery replacement is at the beginning of winter every year, because the important indicator reflecting the performance of a battery is the low temperature and high current discharge capacity. The battery with deteriorated performance may still be used normally when the tem...

Lithium ion battery production process, lithium ion battery pack production line. Objectively speaking, the production process of lithium-ion battery is divided into three sections: the first is the production of electrode, the second is the production of cell, and the third is the battery ass...

What are the disadvantages of dual-computer redundancy in improving the reliability of UPS power supply system? Dual-machine redundancy means backup. If one machine has problems, the reliability of the UPS power supply system will be improved. Generally, two or more single units are used to fo...

The UPS manufacturer tells you the difference between the standard UPS and the long UPS. UPS uninterruptible power supply is generally divided into long machine and standard machine. The long machine must be equipped with external battery pack (with a battery cabinet), and the standard machine...

Is it better to use lithium-ion battery or lead-acid battery for new energy vehicles? Battery is one of the core components of new energy vehicles. According to the type of battery, it can be divided into lead-acid battery and lithium-ion battery. Lithium-ion batteries have higher discharge ef...
