What are the advantages of ternary lithium batteries

　　1、 Better low-temperature discharge performance

　　Compared with other batteries, ternary batteries are more suitable for use at low temperatures, as low temperatures do not affect battery performance. The vast territory of our country results in significant differences in temperature between the north and south of our country. Moreover, China is also a major country in electric vehicles. In cities with significant temperature differences between winter and summer, ternary lithium batteries can better play their role.

　　Compared with the ternary lithium battery, the Lithium iron phosphate battery, which attaches importance to high temperature resistance, can not play its advantages in winter when the temperature is low, and will be extremely weak.

　　2、 Higher energy density

　　At present, according to relevant data, the energy density of the 18650 cylindrical battery made of ternary materials has reached 232Wh/kg, and will continue to increase to 293Wh/kg in the future. And three yuan; Compared with lithium battery, the energy density of Lithium iron phosphate battery is a little lower, which can only reach about 150Wh/kg, and the hope of the energy density of Lithium iron phosphate battery breaking through 300Wh/kg in the future is also very slim.

　　Moreover, for household electric vehicles, batteries with low energy density not only occupy more space, but also have heavier weight, which greatly affects the battery's endurance during use. Relatively speaking, the ternary lithium battery will save more space than the Lithium iron phosphate battery, and will solve the problem of excessive weight.

　　3、 Higher charging efficiency

　　In addition to the advantages in endurance, the ternary lithium battery also has certain advantages in charging. Compared with the Lithium iron phosphate battery, the charging efficiency of the ternary lithium battery is higher. At present, there are two widely used charging methods: constant current charging and constant voltage charging.

　　At the beginning of charging, constant current charging is generally used. At this time, the current is larger and the charging efficiency is higher. After constant current charging, the voltage inside the battery will reach a certain value, which will enter the constant voltage charging stage. This charging method will make the battery charge more fully.
