Currently, there are three types of power lithium-ion batteries: lithium manganese oxide and lithium iron phosphate batteries, and ternary materials. Although ternary materials are being developed both domestically and internationally, they are increasingly lacking in cobalt, resulting in high costs and making it difficult to apply them on a large scale to power lithium batteries. However, they can be mixed with lithium manganese oxide within a certain range. Therefore, the most promising future power batteries are lithium manganese oxide and lithium iron phosphate batteries.
Not long ago, the development of lithium-ion batteries in my country was just beginning. Japan, which heavily relied on lithium manganese oxide, and another important material from the US, achieved great success in Japan a few years later. The US's largest company, A123, produced lithium iron phosphate (LFP), and currently, LFP products are world-leading, but not in mainstream electric vehicle project tenders. Meanwhile, LFP has achieved significant development in Japan. In my country, from the government to companies, there has been strong promotion of LFP, which has suppressed the development of LFP. However, repeated electric vehicle accidents in the near future have been attributed to LFP. The reason is that iron contained in LFP can become elemental iron under certain conditions, leading to internal short circuits—making it the most undesirable battery material. This is why Japan didn't consider LFP and only focused on LFP. Aside from its high-temperature performance defects, LFP has excellent performance. However, research on modified LFP is progressing well, and Japan has largely overcome the defects of LFP. However, the aluminum-doped lithium manganese oxide produced by domestic manufacturers is not inferior to that of Japan. It's inconvenient to mention this name here. It has been proven that its performance is excellent.
In my country, although many manufacturers remain obsessed with lithium iron phosphate (LFP) batteries, even the country's best manufacturers dare not launch mature electric vehicle products on a large scale. Many sober LFP battery manufacturers often choose two paths: first, to consider the development of lithium manganese oxide (LMO) power batteries; second, to develop ternary lithium batteries. However, ternary lithium batteries are insufficient, and as I mentioned, the lack of resources is an insurmountable problem. Therefore, personally, I believe that LMO batteries will be the future masters. Ternary lithium batteries use a mixture of LMO and LFP materials, but due to unavoidable safety issues, they are only suitable for applications with very high safety requirements.
I believe that in the near future, the debate over power between lithium manganese oxide and lithium iron phosphate will soon be over, and your answer will be found. I believe that lithium manganese oxide ion batteries are the best.
