Li2 Mn2 P4 H2 O14

Li₂Mn₂P₄H₂O₁₄ is a lithium manganese phosphate hydrate compound belonging to the class of mixed-metal phosphate semiconductors. This material is primarily of research interest for battery and energy storage applications, particularly as a potential cathode or electrode material in lithium-ion and solid-state battery systems where its layered structure and mixed-valence manganese chemistry could offer advantages in ion transport and electrochemical stability. While not yet widely commercialized, compounds in this phosphate family are attractive alternatives to oxide cathodes because they can provide enhanced thermal stability, lower toxicity, and tunable electrochemical properties—making them candidates for next-generation energy storage where safety and cycle life are critical.
