With the vigorous development of the new energy vehicle industry, the domestic battery industry is growingquickly. As a core element of electric vehicles, the configuration of power batteries plays a vital role. Currently, the battery types selected by various automobile manufacturers on the market are roughly divided into two types, one is ternary lithium battery and the other is lithium iron phosphate battery. The differences between the two are as follows.
1. Different properties
1. Lithium iron phosphate battery: A lithium-ion battery using lithium iron phosphate as the positive electrode material.
2. Ternary lithium battery: The cathode material of lithium battery is lithium-nickel-cobalt or lithium-nickel-cobalt-aluminate ternary cathode material.
2. The main materials are different
1. Lithium iron phosphate battery: The cathode materials of lithium ion batteries mainly include lithium cobalt acid, l acidithium-manganese, lithium-nickel acid, ternary materials and phosphoric acid Lithium iron, etc. Lithium-cobalt oxide is the cathode material of most lithium-ion batteries.
2. Ternary lithium battery: The ternary composite cathode material is composed of nickel salt, cobalt salt and manganese salt as raw materials. The proportion of nickel, cobalt and manganese can be adjusted according to actual needs. .

The advantages and disadvantages of lithium iron phosphate batteries and ternary lithium batteries .
The advantages and disadvantages of lithium iron phosphate batteries: low cost. Lithium iron phosphate batteries do not contain valuable metal elements such as cobalt. Raw materials are easy to obtain and the cost is low. Low temperature performanceare mediocre. In minus 20 degree environment, the performance of lithium iron phosphate batteries will drop to about 55%.
The advantages and disadvantages of ternary lithium batteries: high energy density. The energy density of ternary lithium batteries is high, up to more than 200 Wh per kilogram, and the size and weight of the battery will be smaller. It has good performance at low temperatures. In minus 20 degree environment, the heating performance of ternary lithium battery can still reach more than 70%.
