[it is still debating whether ternary or lithium iron phosphate is better or worse. There are many technical routes for lithium battery cathode materials. At present, ternary and lithium iron phosphate stand in the center of the stage. In terms of performance, price and other aspects, both of them have their own advantages. It will develop in parallel for a long time in the future, and many suppliers have endorsed this point of view with practical actions. After combing the production expansion announcement of the lithium cathode industry chain in the past three months, Science and Technology Innovation Board Daily found that while many ternary material battery manufacturers vigorously develop high-performance material batteries, they are also actively developing lithium iron phosphate batteries.
