The most obvious difference is that iron lithium has a nominal voltage of 3.2-3.3v and manganese has a nominal voltage of 3.6-3.7v. Advantages of iron-lithium system: long theoretical life, large theoretical 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 lithium iron: large volume, heavy weight, poor discharge linearity, and poor low temperature performance.

The lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate as the negative electrode material. Lithium-ion battery cathode materials mainly 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 a lithium ion battery with lithium nickel cobalt manganese ternary positive electrode material as negative electrode material. There are many kinds of anode materials for lithium-ion batteries, including lithium cobaltate, lithium manganate, lithium nickelate, ternary materials and lithium iron phosphate. It reflects their differences in materials, applications and technologies. The difference between the two is that lithium iron phosphate batteries last longer than lithium tri-ion batteries, which are more expensive than lithium tri-ion batteries, and lithium tri-ion batteries are larger than lithium tri-ion batteries.

The so-called lithium iron phosphate battery refers to a lithium ion battery with lithium iron phosphate as the negative electrode material. This battery is characterized by the absence of precious metals such as cobalt. In practical applications, lithium iron phosphate batteries have the advantages of high temperature resistance, strong safety and stability, low price, and good cycle performance.

The ternary lithium ion battery is a lithium ion battery with nickel cobalt manganate as the positive electrode material and graphite as the negative electrode material. Unlike lithium iron phosphate, ternary lithium-ion batteries have a very high voltage platform, which means that ternary lithium-ion batteries have greater 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.
