Strategies to increase power: research and development of lithium iron oxide batteries

　　A few days ago, according to foreign media reports, researchers at Argonne National Laboratory and the Walverton team of Northwestern University in the United States jointly developed a lithium iron oxide rechargeable battery.

　　Recently, according to foreign media reports, researchers at Argonne National Laboratory and the Walverton team of Northwestern University in the United States have jointly developed a rechargeable lithium-iron-oxide battery.

　　We know that the capacity of lithium batteries is mainly limited by the number of transition metal electrons, while the transition metal of lithium cobalt oxide batteries is cobalt, and cobalt is a rare metal, and the global reserves and mining are quite limited. This is also cobalt acid. One of the reasons for the relatively high price of lithium batteries.

　　It is reported that the research team of the Wolferton Laboratory used two strategies of replacing cobalt with iron and forcing oxygen to participate in chemical reactions to improve battery performance on the basis of ordinary lithium cobalt oxide batteries. More importantly, the battery has 4 lithium ions at the beginning instead of one. The capacity of lithium batteries is mainly limited by the number of transition metal electrons. The emergence of this technology means that the capacity of car batteries will be greatly increased.

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