What is a ternary lithium battery? What is the advantage of the ternary lithium battery?

Source: 2020 - 04 - 19 'hits: the role of the ternary lithium battery is very large, in many areas have seen this kind of battery, believe that everybody is familiar to the battery, so what is a ternary lithium battery? Why so popular now? Let us make things clear. 1. What is a ternary lithium batteries ternary lithium batteries ternary material refers to the use of lithium ion batteries ternary nickel cobalt manganese acid lithium and lithium battery anode materials, a lot of people don't know what 'three yuan' refers to, in fact is a nickel, cobalt, manganese salt salt, salt, the proportion of three is not fixed, when we are in the actual production can be adjusted according to actual demand. 2. What is the advantage of the ternary lithium battery 18650 lithium batteries price high safety is the most important feature of this kind of battery with high energy density and high voltage. Therefore, the same weight of the battery pack has a greater capacity, which makes it more effective in the product use. But there is a bad place is not very stable, so at the time of production need to have a layer of steel shell to protect, this can be very good avoid some bad hidden trouble. If using the traditional battery, battery will decomposition of two kinds of material, when they reach a certain temperature, but if you are using the ternary lithium materials, this will be a lower decomposition, and decomposition occurs only at low temperature can reach 200 degrees. From here we can see that the ternary lithium batteries more stable material, panel, even using the main puncture, short circuit, and is basically not burning situation of explosion, test showed that when met with 350 ℃ high temperature did not show the situation of the fire, but if is a common battery, generally not at 180 ℃, so from the aspects of safety, the safety of the ternary lithium battery is very high. At the same time, the safety of the ternary lithium batteries are by companies to upgrade, including the overcharge protection, discharge protection, over temperature protection, etc. As more and more link upgrade, the safety of the ternary lithium batteries have improved largely. High energy density, many people have no idea about the energy density, but in fact, if you want to be more a little bit more simple, the energy density is in a certain space or the amount of energy stored in the quality. To know how much is the energy density of battery, we need to do is to calculate how much battery per unit volume can release energy. The higher the density, the better the performance of storage. Ternary lithium battery unit energy density is high, can reach 150 wh/kg. Can be seen from this aspect we also ternary lithium batteries have great advantages over traditional battery. In addition, there are many companies production units of the ternary lithium battery energy density can reach 200 wh/kg, or even 220 wh/kg. Ternary lithium battery materials due to these advantages, has been widely used in many fields, and important industry of the national policy guide, this also played a large role, with the relevant notice issued by the state in the previous year, made it clear that will need to increase the battery capacity is an important development goals.
