SMM11 March 18: lithium iron phosphate battery, which has experienced peaks and troughs, is showing the momentum of making a comeback. According to the data, the total loading of lithium iron phosphate batteries increased by 127.5% in October compared with the same period last year, up 3.5% from the previous month. The limelight overshadowed the ternary lithium battery.

The installed capacity of iron and lithium accounted for more than 40% in October, and the demand in the passenger car market has increased significantly. Since the second half of this year, the listing of Hongguang MINI and BYD "Han" has driven the market share of iron lithium batteries in passenger cars. With the launch of iron lithium version Model 3 in October, the demand for iron lithium has increased rapidly. In addition, BAIC EU5 and Roewe EI5 are also equipped with lithium iron phosphate batteries in the second half of the year. At present, lithium iron batteries are mostly used in A00 and B, C-class vehicles, mainly suitable for the middle and low-end market of new energy. Iron-lithium technology has also improved significantly this year, such as BYD's "blade battery" and Ningde's CTP technology, which optimize the structure of the battery pack to improve the energy density of the battery, while still maintaining safety and low prices. Therefore, the high performance-to-price ratio and safety of iron lithium also make more and more automobile companies consider supporting iron lithium batteries.
The price of lithium iron phosphate in large factories or a slight increase in prices in small factories is weak.
Since 2020, according to SMM research, the price of lithium iron phosphate shows a downward trend as a whole. Recently, the price of lithium iron phosphate rose slightly. As of November 18, the daily price of lithium iron phosphate was 34500 yuan / ton, up from the lowest level since the beginning of the year.

The price of lithium iron phosphate has been in a downward trend for a long time in recent years, mainly due to overcapacity in the iron-lithium market, fierce competition among iron-lithium manufacturers, the cost reduction target of downstream battery enterprises and the technical optimization of iron-lithium. In the past two weeks, the price of lithium carbonate has increased rapidly, the price of industrial carbon has risen by nearly 5000 yuan / ton, and the prices of phosphates and auxiliary materials have also increased. As the price of iron and lithium has been near the cost line for a long time, the rising price of raw materials has greatly increased the cost pressure of iron and lithium enterprises. The demand for iron-lithium materials in the lower reaches has increased significantly since August, and the head iron-lithium plant has basically reached full production in October. Due to the single supply chain in the power market, large iron-lithium factories are in tight supply, making it difficult to meet the growing demand downstream. Therefore, iron lithium large factories raised prices last week, the price increase in 1000-3000 yuan / ton, has now been transmitted to small and medium-sized battery enterprises. However, other iron and lithium plants are still highly competitive, with an operating rate of less than 50%, and it is difficult for prices to rise. Overall, the price of lithium iron phosphate in large factories is likely to rise slightly in the short term, while the rise in small factories is weak.
Lithium iron phosphate technology is mature
At present, lithium iron phosphate technology is very mature, longer life, safer, more cost-effective.
For example, BYD's blade battery is an improved version of lithium iron phosphate battery. Through structural innovation, it can skip the "module" in the group, greatly improve the volume utilization, and finally achieve the design goal of installing more cells in the same space. Compared with the traditional battery pack, the volume utilization of the "blade battery" has increased by more than 50%, that is, the mileage can be increased by more than 50%, reaching the same level as the high energy density ternary lithium battery.
The power battery CTP is the cell inside the battery that is directly integrated into the battery package. Power battery integration is higher, through this technology also saves a certain link of battery assembly, it can be said that the cost is also greatly saved.
Take the power battery CTP of the Ningde era as an example, the power battery CTP technology of the Ningde era is to directly connect a large number of cells in series and parallel together by omitting the module, and this technology can play a role in reducing the use of parts and components to optimize space utilization, while also reducing the total weight of the battery pack, and achieving the effect of improving battery energy density. At the same time, CTP technology still has an advantage for the power battery module, directly through the fixture through the sleeve or using the installation beam directly installed in the whole vehicle.
Enterprises step up the layout of lithium iron phosphate projects
Recently, the performance of iron-lithium battery is excellent, and its overall demand is driven by the increase in the proportion of iron-lithium in the passenger car market. Many enterprises are stepping up the layout of lithium iron phosphate projects.
The 50,000-ton lithium iron phosphate project invested by Hebei Annezhe New Energy Company is stepping up trial production, and the high-pressure solid nano-lithium iron phosphate cathode materials are being loaded and shipped to all parts of the country. It is understood that the 50,000-ton lithium iron phosphate project is a project of attracting investment in Hequ County in 2019, and it is also the first large-scale new material industry project introduced into Hequ County. With the commissioning of this project, not only lithium iron phosphate batteries can be produced, but also due to the growth of battery demand in the future, projects such as iron phosphate, anode materials, battery diaphragms, battery shells, batteries and battery packs, battery management systems, etc., have been settled in Hequ County, creating a lithium-ion battery industry chain in the county and pulling the economic structure of Hequ County from "relying on coal to eat coal" in the past. It has turned to a new development model of green, economic, safe and efficient.
Recently, the Office of the leading Group for the Construction and Promotion of Major projects in Guangxi Zhuang Autonomous region issued the fourth batch of plans for promoting major projects at the autonomous region level in 2020.
