Explain the difference between ternary lithium ion battery and lithium iron phosphate battery

At present, the new energy vehicle power lithium batteries on the market all use lithium-ion batteries, which can be divided into lithium iron phosphate batteries and ternary lithium-ion batteries. With the advancement of energy conservation and environmental protection, more and more environmentally friendly products are applied to the market. In the battery industry, ternary lithium-ion batteries quickly occupied the market by virtue of many advantages. But most of the consumers are amateurs, and they don't know which is better between ternary lithium ion battery and lithium iron phosphate battery? Today we will explain in detail the difference between ternary lithium ion battery and lithium iron phosphate battery. Three-way lithium-ion battery Three-element lithium-ion battery, also known as ternary polymer lithium-ion battery, refers to lithium nickel cobalt manganate or lithium nickel cobalt aluminate as the cathode material. Ternary lithium-ion batteries are small in size and high in capacity density, and are widely used in new energy vehicles. For example, it is well known that Tesla uses ternary lithium-ion batteries in all its models. Lithium iron phosphate battery Lithium iron phosphate battery is a kind of lithium ion battery, which refers to a lithium ion battery with lithium iron phosphate as the positive electrode material. It has the characteristics of safety, strong stability, high temperature resistance, and good cycle performance. Comparison of energy density of three-way lithium ion battery and lithium iron phosphate battery. The energy density of lithium iron phosphate battery is 120Wh/kg and the group is 80Wh/kg; the energy density of single-group ternary lithium ion battery is 180Wh/kg. And 110Wh/kg. According to statistics, the energy density of ternary lithium-ion batteries is better than that of lithium iron phosphate batteries. Safe comparison The liquid electrolyte of ternary lithium-ion batteries is flammable and explosive, and long-term use can easily cause thermal runaway. During the charging and discharging process, the growth of lithium dendrites can easily pierce the diaphragm, causing short circuits in the battery and posing safety hazards. Lithium iron phosphate batteries have the advantages of high temperature resistance, strong safety and stability, and good cycle performance. Cost comparison Because lithium iron phosphate batteries do not contain precious metal materials, the cost of raw materials can be compressed very cheaply. The ternary lithium ion battery is a lithium ion battery with nickel cobalt manganate as the positive electrode material and graphite as the negative electrode material, and its cost will be much higher than that of the iron phosphate lithium ion battery. For market applications, the battery of the lithium iron phosphate battery is relatively simple, and there is no need to protect the auxiliary equipment too much. Although the battery density of the ternary battery is very high, due to its poor safety and inability to withstand high temperatures, it must be combined with a complex set of Battery protection equipment, the addition of these equipment, and the weight of the car weaken the advantage of the energy density of the ternary battery, and it cannot completely replace lithium iron phosphate. In terms of comprehensive energy density, cycle life, and low-temperature performance, ternary batteries have better comprehensive performance than lithium iron phosphate batteries, but lithium iron phosphate still has a solid position in terms of stability and cost. Which is better, lithium iron phosphate battery or tri-lithium ion battery? Lithium iron phosphate battery has the advantages of large volume, heavy weight, strong safety and stability, high temperature resistance, and good cycle performance, but its large size is not conducive to the use of domestic vehicles. Low-temperature discharge performance is poor; ternary lithium-ion batteries are small in size, light in weight, high energy density, low temperature resistance, and good cycle performance, but ternary lithium-ion batteries are not stable in safety performance. These are lithium iron phosphate batteries and three-component lithium-ion batteries. The advantages and disadvantages of lithium-ion batteries. It is difficult to say which is better, lithium iron phosphate battery or ternary lithium ion battery. We should understand it as the performance difference caused by different materials, and ultimately make the ternary lithium-ion battery more suitable for the future development of electric vehicles. Similarly, there is no good or bad, only suitable or not. It is no coincidence that domestic and foreign automobile companies have the same choice of battery types. It is believed that in the near future, the electric vehicle battery market will be reshuffled, and ternary lithium-ion batteries with the characteristics of low temperature resistance, high energy density, high charging efficiency, good cycle life, and strong safety will also be in the new market.
