Which is better, Sanyuanli or lithium iron phosphate battery?

Lithium ternary battery and lithium iron phosphate battery are both very good, because they have their own advantages and disadvantages, so they are not equal.

If the local climate is cold, then choose ternary lithium battery. Because the ternary lithium battery has good low temperature performance, even in the weather of MINUS 20 degrees, the heating performance can still reach more than 70%.

On the contrary, if the local climate is hot, you can choose lithium iron phosphate battery. Because of the good heat resistance of lithium iron phosphate battery, the temperature of thermal runaway can reach above 800 degrees, and spontaneous combustion will hardly occur in hot areas. The thermal runaway temperature of lithium batteries is only about 200 degrees, which is very dangerous for hot areas.

Advantages and disadvantages of lithium iron phosphate battery and ternary lithium battery

1. energy density: the energy density of ternary lithium battery is about 1.7 times that of lithium iron phosphate, so the volume and weight of ternary lithium battery will be smaller than that of lithium iron phosphate battery, and the load of automobile will be smaller.

2. Safety performance: Lithium iron phosphate battery will perform better in acupuncture test, and its stability in high temperature environment will be far better than that of ternary lithium battery, which means that the natural proportion of ternary lithium battery is larger.

3. Service life: In the process of power attenuation from 100% to 80%, the charging and discharging cycle life of lithium iron phosphate battery can reach more than 3,500 times, while that of ternary lithium battery is only about 2,500 times. And under the same number of cycles, the remaining capacity of lithium iron phosphate battery will be more than that of ternary lithium battery.

4. Low temperature performance: The limit working temperature of lithium iron phosphate battery is minus 20 degrees, and that of ternary lithium battery is minus 30 degrees. In the same low temperature environment, the attenuation of lithium iron phosphate battery will be higher than that of ternary lithium battery.
