Want to know where is the advantage of ternary lithium batteries?solar energy storage lithium ion battery 15kwh 48v 100ah

　　The ternary lithium battery refers to the lithium battery of the three yuan positive materials of the nickel cobalt lithium manganate (Li (NICOMN) O2) or the lithium nickel cobalt aluminum. Salt is raw material. The proportion of nickel cobalt manganese in it can be adjusted according to actual needs. The battery of the ternary material as a positive pole is high than the lithium cobaltate battery, but the voltage is too low. Left and right) There will be a clear sense of insufficient capacity.

　　So, do you want to know where the advantage of the ternary lithium battery is?

　　1. Better low -temperature discharge performance

　　Compared with other batteries, the ternary battery is more suitable for use at low temperature, and low temperature does not affect the performance of the battery. The vast across my country has led to a significant difference in the north -south temperature in my country. In addition, my country is a major electric vehicle country. In cities with obvious temperature difference between winter and summer, ternary lithium batteries can play its role.

　　Compared with ternary lithium batteries, lithium iron phosphate batteries that attach importance to high temperature resistance can not play its advantages in a lower temperature in winter, and it will be extremely weak.

　　Second, the energy density is higher

　　At present, according to relevant data, the energy density of the three -yuan material 18650 cylindrical battery has reached 232Wh/Kg, and it will continue to increase to 293Wh/Kg in the future. Compared with the three yuan; the energy density of lithium iron phosphate batteries is slightly inferior compared to lithium batteries, only about 150Wh/kg, and the hope of exceeding 300Wh/kg of lithium iron phosphate batteries in the future is also very slim. Essence

　　And for household electric vehicles, batteries with low energy density will not only occupy greater space, but also have a heavier quality, and the battery life of the battery will be greatly affected during use. Relatively speaking, the ternary lithium battery can save more space than the lithium iron phosphate battery, and at the same time solves the problem of excessive weight.

　　Third, the higher the charging efficiency

　　In addition to the advantages of battery life, the ternary lithium battery also has certain advantages in charging. Compared with lithium iron phosphate batteries, the charging efficiency of ternary lithium batteries is higher. At present, the widely used charging methods include constant current charging and constant voltage charging.

　　When charging starts, the method of constant current charging is generally used. At this time, the current is large, and the charging efficiency is higher. After the constant current charging, the voltage in the battery will reach a certain value. At this time, it will enter the constant voltage charging phase. This charging method will fill the battery more full.

　　During this charging process, the ratio of the constant current charging capacity to the total battery capacity is called Hengli ratio, which is a key value for us to measure the efficiency of a battery charging. Compared with the lithium iron phosphate battery, the percentage of the ternary lithium battery is greater, which means that the charging efficiency of the ternary lithium battery is higher.
