To figure out which battery is better, we should first have a simple understanding of the difference between the two.
The lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. This type of battery is characterized by the absence of precious metal elements (such as cobalt). Since the precious metal material is not contained, the raw material cost of the lithium iron phosphate battery can be compressed very low. In actual use, the lithium iron phosphate battery has the advantages of high temperature resistance, strong safety and stability, low price and better cycle performance.
The ternary lithium battery refers to a lithium battery using lithium cobalt cobalt manganate as a positive electrode material and graphite as a negative electrode material. Unlike lithium iron phosphate, the voltage platform of the ternary lithium battery is very high, which means that the specific energy and specific power of the ternary lithium battery are larger under the same volume or weight. In addition, ternary lithium batteries have great advantages in terms of large rate charging and low temperature resistance.
Technology is not good or bad, and it is only suitable for different products or environments. On the single battery, there is no such thing as who is better and who is worse. Just applied to the actual use of the scene, the ternary lithium battery is more suitable for the current and future home electric vehicles than the lithium iron phosphate battery.
