We all know that for new energy vehicles, the power battery pack is a very core component, because it directly determines the performance and safety of new energy vehicles. So, how do we evaluate the battery performance and safety of new energy vehicles?
First of all, to talk about lithium iron phosphate, this battery pack is a lithium-ion battery with lithium iron phosphate as the cathode material. Lithium iron phosphate batteries do not contain valuable elements such as cobalt, low cost of materials, and phosphorus, iron in the earth's rich content, so the sale price is cheap. Further, is the current mainstream ternary lithium polymer batteries, this battery pack is characterized by high energy density, good cycle performance
Lithium iron phosphate and ternary lithium batteries in terms of safety, lithium iron phosphate will be higher. For example, ternary lithium batteries will decompose at 200 degrees Celsius; while lithium iron phosphate batteries will decompose only at 800 degrees Celsius. And the more violent chemical reaction of ternary lithium materials, will release a large number of oxygen ions, accelerating combustion. But now the ternary lithium battery pack energy density and higher than lithium iron phosphate, so the mainstream or ternary lithium battery.
But now battery technology is progressing rapidly, with the further development of solid-state battery pack research and development, I believe that the future of new energy vehicles battery pack will be safer.
