Can lithium iron phosphate be used at minus 10 degrees?

Lithium iron phosphate can use the battery normally at minus 10 degrees, but the charging efficiency will be greatly reduced. As one of the current battery types for electric vehicles, lithium iron phosphate batteries are characterized by relatively stable thermal stability, low production costs, and long service life. But its low temperature resistance is very low.

And according to some experiments, when the lithium iron phosphate battery is charged and discharged once a day in an environment of minus ten degrees, it may cause the battery to be scrapped after three months of operation. Because the lithium iron phosphate battery will lead to an increase in internal resistance, capacity attenuation, and even irreversible damage to the battery structure in a low temperature environment.

Why is it said that the north chooses ternary lithium and the south chooses lithium iron phosphate. The ternary lithium battery has the characteristics of high battery density and long cycle life. At the same time, the most important thing is that because the ternary lithium battery is not afraid of the low temperature working environment, more people choose the ternary lithium battery instead of the lithium iron phosphate battery in the low temperature environment in the north.

Compared with the north, the temperature in the south is higher, and the lack of high temperature stability of the ternary lithium battery is a big disadvantage in the south. However, the lithium iron phosphate battery is different. It is the opposite of the ternary lithium battery. The high temperature stability of lithium iron phosphate is one of its major advantages. For example, the chemical composition of the battery begins to decompose slowly when the battery temperature is at a high temperature of 500 or 600 degrees Celsius. Therefore, according to this feature, it is relatively suitable for consumers in the south to choose lithium iron phosphate batteries.
