Iron phosphate batteries and ternary batteries are important -Lithium - Ion Battery Equipment
Is the lithium iron phosphate cell and ternary lithium ion battery be heavy? Nowadays, the arguments of the two popular lithium -ion batteries "lithium iron phosphate cells" and "ternary lithium -ion batteries" have never stopped. This year, the two have been pushed to the forefront. Thham lithium -ion batteries are more adapted to current and future home electric vehicles than lithium iron phosphate battery.
Is the lithium iron phosphate cell and ternary lithium ion battery be heavy?
In the field of new energy vehicles, pure electric vehicles occupy the C position, and in the pure electric vehicle power lithium battery, the ternary lithium ion battery occupies the upper hand, and the lithium iron phosphate ion battery is second. In fact, in 2015, the installed capacity of the three yuan and lithium iron phosphate was about 3: 7, and the time for the three yuan to surpass the lithium iron phosphate was just in 2018, the important reason is that the ternary battery is increasingly the battery life Capability meets the requirements of policy subsidies and meets citizens with farther travel.(Lithium - Ion Battery Equipment)
This does not indicate that lithium iron phosphate has no market in the field of power lithium batteries. In January, BYD said that the company's passenger cars will be equipped with ternary batteries, and passenger cars will continue to use lithium iron phosphate ion batteries. It can be seen that based on safety and stability, in the field of power lithium batteries, lithium iron phosphate will be more widely used in public transportation, logistics and transportation industries. While the new energy subsidy is about to be significantly reduced, policy is likely to not implement new regulations on the endurance capacity of power lithium batteries, and the battery life has reached the demanded and qualified iron phosphate ion battery company will re -seize the some automotive market.
In addition to the field of power lithium batteries, the rise of the energy storage market also gives a better way out of lithium ion batteries. Whether it is large or small energy storage projects, not only the capacity of lithium -ion batteries is required, but also requires safety, stability and long life. It can be seen that the characteristics of lithium iron phosphate cells are more in line with the application of the energy storage industry.
The number of lithium iron phosphate ion battery reincarnation life is 84 %, and the capacity of the three -yuan lithium ion battery is 66 %. Comparison of the number of reincarnation lives is held. Significantly. At this point of reincarnation life, the actual life of lithium iron phosphate ion battery is much longer than the ternary lithium ion battery. Under the number of common turns, the balance of lithium iron phosphate cells is also less than that of ternary lithium -ion batteries.
Compared with the material system, the decomposition temperature of the positive electrode material of the lithium iron phosphate battery pack is about 700 degrees Celsius, and the decomposition temperature of the positive pole material of the ternary lithium -ion battery is about 200 degrees Celsius. In the test environment of the laboratory, short -circuit iron phosphate -ion battery monomers will basically not appear on fire. The ternary lithium ion battery is different, and it will be more likely to fire. Therefore, the three -yuan lithium -ion battery has higher requirements for thermal management, while the lithium iron phosphate cell team has higher adaptability to temperature and safer.
The low temperature performance of lithium iron phosphate cells is flawed. In the Jiangsu and Zhejiang area, at a temperature of 0-5 degrees in winter, the performance of iron lithium is about 75%of the summer, and the large-power vehicle will even be lower under large-power vehicles. Under the same temperature, the ternary lithium -ion battery is about 90%of the summer, and it has declined, but it is not obvious. More relying on the northern area, there will be more declines. Customers in different regions must be considered when choosing lithium battery materials.
From the current technology, the energy density of ternary lithium -ion batteries is generally 200Wh/kg, and it may reach 300WH/kg in the future; while lithium iron phosphate cells are basically hovering at 100 ~ 110Wh/kg. ~ 150Wh/kg, but it is very difficult to break through 200h/kg. Therefore, the ternary material dynamic lithium battery can double more space than the supply of lithium iron phosphate, which is important about cars with limited space.
