How It Compares
Within the oxide oxygen-evolution catalysts class.
Unlike more conventional battery-cathode materials such as LiCoO2 or LiMn2O4, which are primarily optimized for lithium-ion storage, Ta2Mn4O9 is distinguished by its role as a dedicated oxygen-evolution catalyst. While siblings like LaMnO3 share similar transition metal components, Ta2Mn4O9 offers a unique structural configuration that differentiates its catalytic performance from the layered or perovskite structures common to the rest of the class.
