What are the advantages of ternary lithium batteries?lithium trolling motor battery

　　1、 Better low-temperature discharge performance

　　Compared with other batteries, ternary batteries are more suitable for use at low temperatures. Low temperatures do not affect the performance of batteries, as they have a vast territory in China, resulting in significant differences in temperature between the north and south of the country.

　　In addition, China is also a large country of electric vehicles. In cities where the temperature difference between winter and summer is obvious, the ternary lithium battery can play a more important role. Compared with the ternary lithium battery, the Lithium iron phosphate battery, which attaches importance to high temperature resistance, cannot play its advantages in low temperature winter, 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.

　　Compared with the ternary lithium battery, the energy density of the Lithium iron phosphate battery is slightly lower, which can only reach about 150Wh/kg.

　　Moreover, there is little hope that the energy density of Lithium iron phosphate battery will exceed 300Wh/kg in the future.

　　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. When starting 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.

　　In this charging process, the ratio of constant current charging capacity to total battery capacity is called constant current ratio, which is the key value for measuring the charging efficiency of a group of batteries. Compared with Lithium iron phosphate battery, the percentage of ternary lithium battery is higher, which means that the charging efficiency of ternary lithium battery is higher.
