Strategy for increasing power: development of lithium-iron oxide batteries

According to foreign media reports, researchers at Argonne National Laboratory and the Wolverton team at Northwestern University have developed a lithium iron oxide rechargeable battery(Lithium).

We know that the capacity of lithium batteries is mainly limited by the number of electrons in transition metals, while the transition metal of lithium cobalt batteries is cobalt, and cobalt is a rare metal, and the global storage and mining volume is quite limited. This is one of the reasons why lithium cobalt acid batteries are relatively expensive.

It is reported that Wolverton's research team used iron instead of cobalt and forced oxygen to participate in chemical reactions to improve battery performance based on ordinary lithium cobalt acid batteries. More importantly, the battery started with four lithium-ions, not one. The capacity of lithium batteries is mainly limited by the number of electrons in transition metals. The advent of this technology means that the capacity of onboard batteries will be greatly increased.

It can thus be seen that if the new battery can enter the commercial production stage from the laboratory stage, the endurance of pure electric vehicles is expected to increase 3-4 times.
