What Are The Main Differences Between Lithium Battery And Lithium Iron Phosphate Battery?

The ternary cathode material, as the name suggests, contains three chemical elements. At present, ternary cathode materials are mainly divided into NCM and NCA. Each letter represents a corresponding chemical element, which are nickel (Niccolum), cobalt (Cobalt), and manganese / Aluminium. The advantages of ternary lithium batteries mainly lie in energy storage density and low temperature resistance.

Service life

Lithium iron phosphate battery charge and discharge cycles will start to decay after about 3500 times, and its service life can be as long as ten years, but the ternary lithium battery charge and discharge cycle times are only 2000, which means that its service life is only 6 years .

Safety performance

Both lithium iron phosphate batteries and ternary lithium batteries will decompose when they reach a certain temperature. The decomposition temperature of the former is higher than that of ternary lithium batteries (ternary materials are about 200 ℃, lithium phosphate batteries are about 800 ℃). In contrast, lithium iron phosphate batteries are more adaptable and safe to temperature.

However, with the enhancement of overcharge protection, over-discharge protection, over-current protection, and over-temperature protection in the manufacturers, the two batteries are working in a safe state to reduce potential safety hazards.

Cost aspect

Since lithium iron phosphate batteries do not contain precious metal materials, the cost of raw materials can be appropriately reduced. The ternary lithium battery uses nickel cobalt manganese oxide as the positive electrode material and graphite as the negative electrode material. Among them, the cobalt element has less reserves in China, most of which are imported from overseas, and are greatly affected by market fluctuations. The overall cost will be higher than that of lithium iron phosphate batteries. A lot more expensive.

What are the main differences between ternary battery and lithium iron phosphate battery?

Compared with traditional lithium iron phosphate, the ternary cathode material has a higher specific capacity, which can greatly increase the energy density of the battery, thereby supporting the demand for "high endurance" capabilities of new energy vehicles and other end products. In general, the ternary lithium battery has great advantages in terms of large rate charging and low temperature resistance.
