Which is the best of lithium iron phosphate batteries and ternary lithium batteries

The core technology of new energy vehicles is a battery that provides energy. After years of development, the ternary lithium and metal phosphate are the two mainstream technologies, which have been widely promoted and applied. So which is the best iron phosphate battery and ternary lithium battery?

The ternary lithium battery is better. The three -yuan lithium battery has a longer life, higher energy density, and lighter weight.

The advantages of lithium iron phosphate batteries are: higher safety, longer service life, low raw material cost, support fast charging, wide working temperature range, stability is the best in car batteries at present; disadvantages: energy density and three three There is still a large gap compared to the Yuan Lithium Battery. When the temperature is lower than -10, the charging efficiency decreases, and when the temperature is too low, the battery capacity will be affected. Models used in lithium iron phosphate batteries are not suitable for driving north, especially in extremely cold areas such as Northeast China.

The advantages of the ternary lithium battery are: high energy density, good circulation performance, and more suitable for the development trend of new energy vehicle batteries in the future, suitable for the northern weather, more stable at low temperature; disadvantages: Ni-Co-AL's high temperature structure unstable leads to high temperature safety Poor sexuality leads to danger. However, this problem can be improved through various systems, and the current cost can be higher.

In contrast, the ternary lithium polymer has a high -energy density and low temperature resistance that cannot be compared with lithium iron phosphate batteries, and is better than lithium iron phosphate batteries. In the future development of new energy vehicles, the ternary lithium battery can solve the problem of safety and cost, and can be used as a new type of energy storage equipment for future cars.
