Comparison of advantages and disadvantages of ternary lithium battery and lithium iron phosphate battery

Compared with ternary lithium batteries, lithium iron phosphate batteries have lower cost and better thermal runaway performance. However, poor low-temperature discharge performance and low energy density are also common problems of lithium iron phosphate batteries. However, with the blessing of new technologies, lithium iron phosphate batteries have begun to gradually match the performance of ternary lithium batteries.

A few days ago, some media reported that Weilai Motors had already contracted a lithium iron phosphate battery production line in the Ningde era, and the lithium iron phosphate version is being tested.
The NIO equipped with lithium iron phosphate version will be launched this year, mainly involving the starting version, to satisfy consumers who are relatively price-sensitive and consumers who like lithium iron phosphate batteries.

However, Weilai said in this regard: "We did not have a production line, but Ningde Times used one of its lithium iron phosphate production lines to produce our 100-degree batteries."

Which ternary lithium battery is cheaper than lithium iron phosphate battery?
Hearing Weilai's response, many netizens said they were even more confused. The NIO 100kWh battery pack is a ternary lithium battery. Why did the Ningde era use the lithium iron phosphate battery production line to produce it?

Some netizens also speculated that the production line of ternary lithium batteries in the Ningde era is already full, and lithium iron phosphate battery production lines can only be used instead.

Currently, Tesla has begun to use lithium iron phosphate batteries, but Li Bin has also said before that Weilai wants to become a BBA in electric vehicles, while Tesla is rushing to become the goal of car companies such as Volkswagen and Ford. .
Therefore, NIO, which is positioned more high-end, will not follow Tesla's use of lithium iron phosphate batteries and continuous price reductions for the time being.
