Doubling the capacity of iron oxide-type cathodes for cost-effective Li-ion batteries

https://techxplore.com/news/2023-01-capacity-iron-oxide-type-cathodes-cost-effective.html

"cost-effective, safe... utilizing both the iron and oxygen redox is difficult to achieve... mechanochemical alloying approach to bring Li5FeO4 to a metastable phase. The fabricated metastable Li5FeO4 exhibited iron and oxygen redox... 2X capacity of LiFePO4... will lead to cost-effective, high-capacity Li-ion batteries based on abundant materials"
