What is the difference between ternary lithium battery and lithium iron phosphate battery

　　The most obvious difference is that the nominal voltage of lithium iron is 3.2-3.3v, and the nominal voltage of manganese is 3.6-3.7v. Advantages of iron lithium system: long theoretical life, large theoretical overcharge and overdischarge resistance. Advantages of ternary system: high energy density, good low-temperature performance, small size, good discharge linearity. Disadvantages of iron lithium: large volume, heavy weight, poor discharge linearity and poor low-temperature performance.

　　Lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate as cathode material. The cathode materials of lithium ion batteries include lithium cobalt, lithium manganese, lithium nickel, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material of most lithium ion batteries.

　　Ternary polymer lithium ion battery: refers to the lithium ion battery with lithium nickel cobalt manganese ternary cathode material as the cathode material. There are many kinds of anode materials for lithium ion batteries, including lithium cobalate, lithium manganate, lithium nickel oxide, ternary materials and lithium iron phosphate. It reflects their differences in materials, applications and technologies. The difference between the two is that the life of lithium iron phosphate battery is longer than that of lithium tri ion battery, lithium tri ion battery is more expensive than that of lithium tri ion battery, and lithium tri ion battery is larger than that of lithium tri ion battery.

　　The so-called lithium iron phosphate battery refers to the lithium ion battery with lithium iron phosphate as the cathode material. The battery is characterized by no cobalt and other precious metals. In practical applications, lithium iron phosphate battery has the advantages of high temperature resistance, high safety and stability, low price, and good cycling performance.

　　Ternary lithium ion battery is a kind of lithium ion battery with nickel cobalt manganate as cathode material and graphite as cathode material. Different from lithium iron phosphate, ternary lithium ion batteries have a very high voltage platform, which means that ternary lithium ion batteries have higher specific energy and specific power under the same volume or weight. In addition, ternary lithium ion batteries have great advantages in high-speed charging and low temperature resistance.
