What is the advantage of the ternary lithium battery?solar energy storage lithium ion battery 15kwh 48v

　　1. Better low -temperature discharge performance

　　Compared with other batteries, the ternary battery is more suitable for use at low temperatures. The low temperature does not affect the performance of the battery. It is vast in my country, which leads to a significant difference in the temperature in the north and south of my country.

　　In addition, my country is a major electric vehicle country. In cities with obvious temperature difference between winter and summer, the ternary lithium battery can play its role. Compared with the ternary lithium battery, the lithium iron phosphate battery that attaches importance to high temperature resistance is Its advantages 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 ternary lithium batteries, the energy density of lithium iron phosphate batteries should be slightly inferior, only about 150Wh/kg.

　　And in the future, the energy density of lithium iron phosphate batteries will exceed 300Wh/kg in the future.

　　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 method has two types: constant current charging and constant voltage charging. When the charging starts, the constant current charging method 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. It is the key value of us to measure the efficiency of a set of battery charging. Compared with the lithium iron phosphate battery, the percentage of the ternary lithium battery is more percentage. Large means that the charging efficiency of the ternary lithium battery is higher.
