Lithium iron phosphate battery packs and ternary batteries are all types of lithium batteries, although the raw material management systems of the two are still very different, and the main performance characteristics are also different. Lithium iron battery with excellent high temperature characteristics and ternary battery with excellent low temperature characteristics. In terms of safety, lithium iron phosphate is better. Regarding the difference between the lithium battery pack and the ternary battery, let's first briefly understand the composition of the raw materials and the basic principles of the circulation system of the two rechargeable batteries, and then talk about it.
Lithium iron phosphate battery: Lithium iron phosphate battery pack refers to a lithium battery composed of a variety of lithium batteries using lithium iron phosphate battery as the battery cathode material. This kind of raw material does not contain precious elements like cobalt, which can make the cost of lithium iron phosphate rechargeable batteries lower than other lithium batteries. In addition, mineral elements such as phosphorus and iron are rich in resources on the earth, and it is not easy to encounter the problem of insufficient supply of raw materials.
Ternary battery: Ternary polymer lithium battery refers to a lithium battery made of ternary composite battery cathode material using lithium nickel cobalt manganese oxide or lithium nickel cobalt aluminate. The battery cathode material is nickel salt, cobalt salt, and manganese. Salt is the raw material, and the content of nickel, cobalt and manganese can be adjusted according to the specific requirements.
The difference between lithium battery pack and ternary battery:
1. The working voltage service platform of the ammeter lithium battery is the key index value of its specific energy, which determines the basic characteristics and cost of the rechargeable battery. The higher the operating voltage, the greater the specific volume; for lithium batteries with the same volume, net weight and ampere hour, the operating voltage service platform of the ternary battery is higher than that of the lithium iron phosphate battery rechargeable battery, and the high transmission line reaches ampere, the charging and discharging service platform Reach or reach ampere.
2. Discharge performance. Because of the complex climate on the earth, from the earth's equator to the poles, from high temperature to extreme freezing, the natural environment for the application of lithium batteries will be very different. However, under different temperature and natural environments, the characteristics and hazards of lithium iron phosphate battery packs and ternary batteries are very different. Lithium iron phosphate battery packs focus on charging and discharging applications in high temperature natural environments, and ternary batteries focus on low temperatures. Charge and discharge application in natural environment.
3. Cycle life. Although the service life of the cycle system of lithium iron phosphate battery pack and ternary battery is longer than that of other types of lithium batteries, but to compare the service life of the cycle system of lithium battery and ternary battery, it can only be said that the service life of lithium iron phosphate battery pack is longer than that of other types of lithium batteries. The ternary battery is much longer.
Generally speaking, the service life of the cycle system of lithium iron phosphate battery packs is generally above 2000 times, while the service life of the ternary battery cycle system is generally above 1000 times. There is a big difference between the two in the cycle system service life. Lithium batteries of various models and specifications have more or less differences, the biggest difference still depends on the positive battery cathode material. Due to the different constituent materials, there will be differences in the characteristics of lithium batteries at many levels.
