Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. This type of battery is characterized by no precious metal elements (such as cobalt, etc.). In actual use, lithium iron phosphate battery has the advantages of high temperature resistance, strong safety and stability, low price and better cycle performance.
Ternary material lithium battery refers to a lithium battery that uses lithium nickel cobalt manganate as the positive electrode material and graphite as the negative electrode material. Unlike lithium iron phosphate, the ternary lithium battery has a high voltage platform, which means that the specific energy and specific power of the ternary lithium battery are greater under the same volume or weight. In addition, ternary lithium batteries also have great advantages in terms of high-rate charging and low-temperature resistance.
The advantages of the iron-lithium system: nominally long life, nominally excellent overcharge and overdischarge resistance.
The advantages of the ternary system: high energy density, good low temperature performance, small size, and good discharge linearity.
Disadvantages of iron lithium: large volume, heavy weight, poor discharge linearity, and poor low temperature performance.
Disadvantages of the ternary system: slightly poor cycle life, poor life under high temperature conditions.
In short, when you buy lithium batteries, please choose a regular brand. Tell the manufacturer the specific parameters, use, maintain, charge and discharge in the correct way. To ensure the safety during the use of the product !
