Which is better with lithium iron phosphate and ternary material, lithium iron phosphate and ternary?

Lithium batteries and lithium iron phosphate batteries have their own

Typical voltage of lithium iron phosphate monomer 3.2 V, lithium ion 3.7 V

Lithium iron phosphate is resistant to overcharge and overdischarge, and can recover more than 80 % when it is put to 0 in a short time. Inreversible damage occurs when lithium ions are placed on 2.6 V.

Lithium iron phosphate is resistant to overcharging to 100 % and will not explode. If lithium ions exceed 4.35 V, they will swell.

Lithium iron phosphate puncture does not catch fire and does not explode. Lithium-ion will. It's a little safer now.

Lithium iron phosphate is resistant to high temperatures and can be used after more than 200 degrees of recovery. Lithium-ion doesn't work.

Lithium iron phosphate can discharge large currents, 10C20C or more, lithium ions can only discharge 3 ~ 5C

In terms of above, lithium iron phosphate is the safest of lithium batteries.

However, the energy density of lithium iron phosphate is not as large as that of lithium ion batteries. The voltage is also relatively low. Due to its large discharge characteristics, it mainly uses power sources such as electric vehicles and flight models. The large capacity of lithium ions is mainly used in the field of civilian consumption. So look at the different types of batteries that you choose to use in what way.

Which is better, lithium iron phosphate and lithium trioxide?

After 30 years of development, lithium-ion batteries have greatly improved their performance than energy and specific power, and have been successfully applied to automobiles. Due to the limitation of battery ratio, the limited range of pure electric vehicles is a bottleneck that restricts development. Foreign auto factories have recently planned to develop hybrid vehicles. The positive electrode materials currently used in lithium ion batteries mainly include lithium manganate, lithium iron phosphate, lithium cobalt phosphate, and ternary materials. At present, the power batteries used mainly use lithium iron phosphate and ternary materials.

From Figure 1 and Table 1, it can be concluded that the positive electrode uses 19.4 % higher discharge capacity than lithium iron phosphate, 37.5 % higher energy, and 39.7 % higher discharge power. Because the quality ratio and compaction density of ternary material are higher than that of lithium iron phosphate material, the use of ternary material batteries has a great advantage.

As can be seen from the above figure and the above table, there is no significant difference between the constant current charging volume/total capacity ratio when the three-element material battery and the lithium iron phosphate material battery are charged not more than 10C. When the 10C multiplier rate is charged, the constant current charging volume/total capacity ratio of the lithium iron phosphate battery is small. The greater the charging ratio, the more obvious the gap between the constant current charging volume/total capacity ratio and the ternary material battery. This is mainly related to the fact that lithium iron phosphate has a smaller voltage change in 30 % to 80 % of the SOC, such as the negative electrode using soft carbon or hard carbon., Lithium-iron phosphate batteries can be rechargeable to the level of ternary batteries.

In Figure 3, the three-part material battery has a residual capacity of 3,900 times, and the lithium iron phosphate battery has a residual capacity of 5,000 times. The recycling life is more than that of a three-part material battery. The lithium iron phosphate battery has a significant advantage. According to the residual capacity/initial capacity = 80 % as the test end point, the current 1C cycle life of the three-part material battery laboratory is about 2,500 times, and the 1C cycle life of the lithium iron phosphate battery laboratory is more than 3,500 times, and some of them reach more than 5,000 times.

The discharge comparison of batteries at different temperatures is shown in Figure 4. Discharge at 55 °C, three-part material battery and lithium iron phosphate at room temperature, discharge capacity is not different, discharge at -20 °C, three-part material battery discharge capacity/room temperature ratio is higher than lithium iron phosphate battery 15 %, as shown in table 3.

In this paper, by making batteries of the same structure, the advantages and disadvantages of ternary materials and lithium iron phosphate materials in the application of HEV batteries are obtained. The ternary materials have advantages in terms of battery power, specific power, high power charging, and low temperature performance. In terms of recycling performance, lithium iron phosphate has obvious advantages, and lithium iron phosphate batteries are also superior to ternary materials in safety. When selecting a battery, it can be selected according to different uses. For example, the space of a bus is large, the energy and power requirements of the battery are relatively low, and lithium iron phosphate material batteries can be selected to give play to its good cycling performance. The car space is limited, and the battery usage is small., The high specific energy and high specific power ternary material batteries are more suitable.

At present, the energy density of lithium iron phosphate batteries has basically reached the extreme of theory, and the energy density of ternary batteries still has a lot of room for improvement. The comprehensive capability density, power density, cycle life, low temperature performance and so on, ternary batteries are superior to lithium iron phosphate batteries.

The so-called lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive material. This type of battery is characterized by no precious metal elements(such as cobalt, etc.). In practical use, lithium iron phosphate batteries have the advantages of high temperature resistance, strong safety and stability, cheap prices, and better recycling performance.

Lithium batteries of ternary materials refer to lithium batteries that use lithium nickel-cobalt manganese acid as a positive material and graphite as a negative material. Unlike lithium iron phosphate, the three-element lithium battery voltage platform is very high, which means that at the same volume or weight, the three-part lithium battery has more energy than power. In addition, in terms of high rate charging, and low temperature resistance, ternary lithium batteries also have great advantages.

On batteries alone, there is no such thing as who is better and who is worse. It is only applied to the actual use scenario that the triple-lithium battery is more suitable for today's and future home electric vehicles than the lithium iron phosphate battery.
