In fact, ternary lithium battery and lithium iron phosphate battery are not absolutely good or bad, but each has its own advantages. Among them, ternary lithium ion battery has the advantages of high energy storage density and low temperature resistance. First of all, in terms of energy storage density, the ternary lithium ion battery can reach 240 whkg due to its high voltage, which is almost 1.7 times that of the lithium iron phosphate battery 140 whkg (this article is original, Sanmao looks at the car first, please indicate the transfer); At the same time, compared with NCA (nickel cobalt aluminum) and NCM (nickel cobalt manganese) batteries, NCA has better performance. However, due to the low thermal runaway temperature, high manufacturing process requirements, high cost and technology of Japanese and Korean automobile enterprises, the research and development of NCM batteries in China is very important. At present, it is divided into 111, 523, 622 and 811 according to the proportion of ternary materials.
881 high nickel battery has become a key breakthrough direction, because it is the key to improve battery energy density; Secondly, in terms of low temperature resistance, the low temperature use limit of ternary lithium ion battery is - 30 degrees, which is more favorable than that of lithium iron phosphate battery, which is - 20 degrees. At the same time, under the same low temperature conditions, the attenuation of ternary lithium ion batteries in winter is less than 15%, which is significantly higher than that of lithium iron phosphate batteries by more than 30%. This is more suitable for why BYD sells well in the northern market in the south. However, lithium iron phosphate also has advantages in three aspects. First, the safety is high, because the thermal runaway temperature of lithium iron phosphate batteries is generally above 500 degrees, the thermal runaway temperature of ternary lithium ion batteries is below 300 degrees, and the thermal runaway temperature of some high nickel batteries is even below 200 degrees.
In contrast, the risk of spontaneous combustion of lithium iron phosphate battery during high-speed driving and rapid charging is low. Secondly, the cycle life is long, because the lithium iron phosphate battery will start to decay after more than 3500 charging and discharging cycles, that is, the service life can reach about 10 years, but the charging and discharging cycles of the ternary lithium ion battery are only 2000, that is, the service life is only 6 years, showing the gap between the two; Third, the manufacturing cost is low, because lithium iron phosphate is far away from the secondary battery and there is no precious metal, so the production cost is low. On the other hand, as ternary lithium-ion batteries use cobalt metal, 70% of their reserves are in the Democratic Republic of the Congo in Africa, which makes their import prices soar. The current quotation has reached 200000 yuan tons, while the quotation of electrolytic nickel is 110000 yuan tons, which is another key reason for forcing battery companies to adopt the 811 technology route;
