Which is better for replacing lithium batteries in electric vehicles, lithium ternary or lithium iron phosphate?

Whether a battery is good or not is actually determined by several dimensions. Little experts analyze the ternary lithium battery and the lithium iron phosphate battery from the four dimensions of safety, price, endurance, and lifetime. After comparison, they can accurately determine which is better and which is the lithium battery they want.

Safety: Lithium Iron Phosphate Battery>Lithium Iron Phosphate Battery

At present, many people prefer lead-acid batteries to lithium batteries. Considering the safety problem, many electric vehicles have experienced spontaneous combustion in the past two years, which makes people have a certain fear of lithium batteries. However, from the safety point of view, many electric vehicles with spontaneous combustion are ternary lithium batteries. Due to the good stability of material performance, the battery structure of lithium iron phosphate battery will not change during charging and discharging, it will not burn or explode. As long as there is no short circuit, extrusion, acupuncture and other special circumstances, it is relatively safe. If safety is considered, lithium iron phosphate battery will be better.

Price: Ternary Lithium Battery>Lithium Iron Phosphate Battery

As far as I know, most car owners will consider the price difference when buying electric vehicles or replacing batteries. To a certain extent, price is an important factor that leads us to make a choice. In terms of price, lithium iron phosphate battery and ternary lithium battery will be cheaper in terms of raw materials because they can hardly use heavy metals and rare metals. In the normal market, the cost of ternary lithium battery is 0.85-1 yuan/wh, the cost of lithium iron phosphate battery is only about 0.58-0.6 yuan/wh. If the price is considered cost-effective, lithium iron phosphate battery is preferred.

Endurance: Ternary Lithium Battery>Lithium Iron Phosphate Battery

Endurance is a factor to consider when using electric vehicles as transportation vehicles. Although the overall endurance of lithium batteries is better than that of lead acid batteries, there is still a certain gap in endurance between ternary lithium batteries and lithium iron phosphate batteries, mainly due to the difference in energy density. The energy density of ternary lithium batteries is between 200-300Wh/kg, while the energy density of lithium iron phosphate battery is below 200Wh/k, which also means that under the same capacity battery, ternary lithium batteries can run farther, and in addition, ternary lithium has a lighter weight, which is beneficial for increasing battery life.

Service Life: Lithium Iron Phosphate Battery>Ternary Lithium Battery

It is said that the life of lithium battery is very long, but if you want to choose a lithium battery for a long life, you must choose the right battery. The difference between the life of ternary lithium battery and lithium iron phosphate battery is relatively large. From the theoretical number of charge and discharge, the ternary lithium battery used for electric vehicles is 800~1000 times, and the lithium iron phosphate battery used for electric vehicles is 3000 times.

If an electric vehicle is basically charged every day, the life of the ternary lithium battery can reach 3-5 years, while the lithium iron phosphate battery can last 8-10 years.

Final summary:

The question of which is better, “ternary lithium” or “lithium iron phosphate”, has always been discussed. However, from the above objective analysis, we can see that both have their own advantages. So if we say which one has more advantages, we can get a clear answer. lithium iron phosphate battery will have more advantages, and it will be better than ternary lithium battery in price, safety and service life.

Then, when the car owner changes the battery for the sake of safety, life and price, it will be better to choose lithium iron phosphate battery as the first choice. If only the endurance is better, the ternary lithium battery is the best choice. By understanding the characteristics of the battery, when you choose the battery, you can accurately match the battery you want. The one that suits you is the best
