About lithium manganese dioxide
LiMnO2 is a thermodynamically stable layered lithium transition-metal oxide that functions as a semiconducting material. Its robust structural framework and the abundance of reported configurations make it a significant subject of study for understanding ion transport and structural evolution in energy storage systems.
This compound is primarily investigated for its potential in high-capacity electrochemical applications. Its stability on the convex hull suggests a favorable energy landscape, positioning it as a key candidate for developing next-generation cathode materials that aim to balance performance with material availability.
Key Properties
Cross-validated computational properties for lithium manganese dioxide, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.

How It Compares
Within the layered lithium transition-metal oxides class.
Within the diverse family of layered lithium transition-metal oxides, LiMnO2 offers a distinct alternative to the widely commercialized LiCoO2. While LiCoO2 is the industry standard for traditional lithium-ion batteries, LiMnO2 is favored for its reliance on more abundant manganese, distinguishing it from nickel-rich counterparts like LiNiO2 and complex spinel structures such as LiMn2O4.
