Fe3Li5Mn2O10
Fe3Li5Mn2O10 is a semiconducting, metastable layered oxide containing lithium, iron, and manganese that is being investigated for its potential in electrochemical energy storage.
About Fe3Li5Mn2O10
Fe3Li5Mn2O10 belongs to the class of layered lithium transition-metal oxides, characterized by its complex arrangement of iron, lithium, and manganese within an oxygen framework. As a semiconducting material, it offers unique electronic properties that distinguish it from traditional insulating oxides, making it a focus for researchers exploring novel electrode architectures.
Although it is classified as a metastable phase, its existence across multiple structural reports highlights its significance in the study of lithium-rich transition metal systems. Its potential utility lies in its ability to facilitate ion transport and charge storage, which are critical factors for the development of high-performance battery technologies.
Key Properties
Cross-validated computational properties for Fe3Li5Mn2O10, aggregated across 3 databases.

How It Compares
Within the layered lithium transition-metal oxides class.
Unlike the highly stable and widely commercialized LiCoO2 or LiMn2O4, Fe3Li5Mn2O10 exists as a metastable phase, presenting a more complex structural challenge for synthesis and application. While siblings like LiNiO2 are well-established in industrial battery cathodes, this iron-manganese-based compound represents a more experimental frontier in the search for alternative, earth-abundant transition metal oxides.
