The development of lithium iron phosphate batteries can be divided into the following important stages:
Initial stage (1996): In 1996, Professor John Goodenough of the University of Texas led A.K. Padhi and others to discover that lithium iron phosphate (LiFePO4, referred to as LFP) has the characteristics of reversibly migrating in and out of lithium, which inspired the global research on lithium iron phosphate as a positive electrode material for lithium batteries.
Ups and downs (2001-2012): In 2001, A123, founded by researchers including MIT and Cornell, quickly became popular due to its technical background and practical verification results, attracting a large number of investors, and even the US Department of Energy participated. However, due to the lack of electric vehicle ecology and low oil prices, A123 filed for bankruptcy in 2012 and was eventually acquired by a Chinese company.
Recovery stage (2014): In 2014, Tesla announced that it would make its 271 global patents available for free, which activated the entire new energy vehicle market. With the establishment of new car-making forces such as NIO and Xpeng, the research and development of lithium iron phosphate batteries has returned to the mainstream.
Overtaking stage (2019-2021): From 2019 to 2021, the advantages of lithium iron phosphate batteries in cost and safety enabled its market share to surpass ternary lithium batteries for the first time. CATL introduced its Cell-to-Pack module-free technology, which improved space utilization and simplified battery pack design. At the same time, the blade battery launched by BYD also increased the energy density of lithium iron phosphate batteries.
Global market expansion (2023 to present): In recent years, the share of lithium iron phosphate batteries in the global market has gradually increased. Goldman Sachs expects that by 2030, the global market share of lithium iron phosphate batteries will reach 38%.
