The first thing to be clear is that the cold in winter will have a certain impact on the activity of lithium iron phosphate and ternary lithium-ion batteries. Compared with ternary lithium-ion batteries, lithium iron phosphate batteries decay faster. This is because the battery energy density of the lithium iron phosphate battery pack is low. The design of the lithium iron phosphate battery pack is different. It is not the same as the ternary lithium ion battery pack. The single cell is installed in a separate installation mode, which also makes The lithium iron phosphate battery pack has poor cold resistance.

　　Therefore, if the battery life of the lithium iron phosphate battery pack is the same as that of the tri-lithium-ion battery pack, the deterioration of the battery life performance of the lithium iron phosphate battery pack will be more serious if it is in a winter environment. However, the current blade battery design solves the compactness limitation of the lithium iron phosphate battery pack, so the lithium iron phosphate battery pack can also reach the level of the ternary lithium ion battery pack. Solid-state batteries may replace these two types of batteries in the future.
