· JVASP-44344· Li3Mn2FeB3O9

Li₃Mn₂FeB₃O₉ is a lithium-based mixed-metal oxide ceramic compound containing manganese, iron, and borate components. This material is primarily of research interest as a potential lithium-ion battery cathode or electrolyte material, belonging to the family of polyanionic compounds being investigated for next-generation energy storage applications. The combination of lithium, transition metals (Mn, Fe), and borate groups positions it as a candidate for exploring improved electrochemical performance, though it remains largely in the experimental phase compared to commercially established battery ceramics.
