· Li4 Mn4 P4 O16

Li₄Mn₄P₄O₁₆ is a lithium manganese phosphate compound belonging to the polyphosphate ceramic family, synthesized as a research material for energy storage applications. This compound is primarily investigated for cathode material development in lithium-ion battery systems, where its mixed-valence manganese framework and polyphosphate structure offer potential advantages in cycling stability and thermal robustness compared to conventional oxide cathodes. As an experimental material rather than a commercialized product, it represents the broader research effort to develop alternative lithium-based compounds with improved safety, cycle life, and cost-effectiveness for next-generation battery technologies.
