Compare Ternary and LifePo4 Battery

In recent years, new energy vehicles are booming, domestic battery industry to promote the explosive growth of the core power battery electric vehicles, electric vehicles using LifePo4 batteries are ternary lithium battery, LifePo4 mainly discussed below ternary lithium battery advantages and disadvantages.

At present, new energy vehicles, the main use of LifePo4 batteries, but limited theoretical energy density LifePo4 batteries, LifePo4 monomer energy density of 120Wh / kg, after the group energy density of 80Wh / kg, So now companies are actively developing higher energy density lithium phosphate material ferromanganese new power lithium battery. The three yuan higher battery energy density, ternary lithium battery energy density of the monomer 180Wh / kg, after a group of 110Wh / kg, corresponding market have obvious advantages. Therefore, in terms of energy density, three better than the LifePo4 lithium battery.

Speaking from the safety of LifePo4 batteries has more advantages than three yuan. The reason is that nickel-cobalt-aluminum ternary material 18650 Chaoguo 180 ℃ will self-heating, it is difficult to control after the fire, while the LifePo4 material to 250 ℃ exothermic phenomenon will occur. From the cycle of life in terms of LifePo4 battery quite ternary, single cell cycle life of more than 3000, after the group, because the work environment is complex, life has declined.

In general, the theoretical energy density LifePo4 is limited, there is no room for improvement, and three yuan lithium battery there is still much room for improvement, but three yuan battery safety LifePo4 does not high, both circulation life considerably. Because both have advantages and disadvantages, so the applications are different. Battery battery enterprises should pay more attention to safety, to strengthen the production monitoring, strict quality assurance, in order to ensure the safe use of new energy vehicles and multiply employment safety.
