**What is Lithium Iron Phosphate?**
Lithium iron phosphate (LiFePOâ‚„) is a type of cathode material used in lithium-ion batteries. It has gained attention due to its high discharge capacity, low cost, non-toxic nature, and environmental friendliness. Countries around the world are striving to commercialize it. However, one of its limitations is its low tap density, which can affect the battery's energy density. The most common production method today is high-temperature solid-state synthesis, resulting in relatively stable product performance.
The performance of lithium-ion batteries largely depends on their cathode and anode materials. Lithium iron phosphate as a cathode material is relatively new, with large-capacity versions first developed in China in July 2005. It offers excellent safety and long cycle life, making it ideal for power batteries. These batteries can undergo over 2000 cycles at 1C charge/discharge rates. They are also highly safe, withstanding overcharge up to 30V without catching fire or exploding, even when punctured. This makes LiFePOâ‚„ suitable for use in electric vehicles, where frequent charging and discharging are required. Its advantages include being non-toxic, eco-friendly, cost-effective, and having a long service life, making it a promising candidate for next-generation lithium-ion batteries.
**Lithium Iron Phosphate Production Ranking**
In 2017, the output of lithium iron phosphate from 21 domestic manufacturers reached 74,400 tons, nearly matching the previous year’s figures. Among the top producers, Betray, Sublimation Technology, and BYD were the leading companies, with significant changes in rankings compared to 2016.
The market environment for lithium iron phosphate was very different in 2016 and 2017. In 2016, under the ban on ternary materials in commercial vehicles, lithium iron phosphate experienced explosive growth, reaching 73,900 tons with a growth rate of 130%. However, starting in 2017, government subsidies for new energy vehicles began to prioritize higher energy density batteries, leading to a preference for ternary materials in commercial applications. As a result, many manufacturers shifted towards ternary materials, causing a decline in demand for lithium iron phosphate.
This shift had a significant impact on companies that relied heavily on lithium iron phosphate. For example, Jiangxi Jinli, Zhejiang Ruibang, and Henan Langtai saw a sharp drop in production in 2017. Additionally, companies that planned to expand in 2017, such as Deyang Weixu, Jiangxi Tong Li, and Sanqiu New Energy, faced difficulties in achieving mass production.
**Production Yield Overview**
In 2017, Betray and Sublimation Technology both saw notable growth. Betray, with its long-standing expertise in anode materials, quickly expanded into the cathode market and established strong partnerships with major battery manufacturers. Sublimation Technology benefited from stable supply chains and the expansion of its Yichun plant, leading to increased overall production.
