· Li4 Mn2 C2 S2 O14

Li₄Mn₂C₂S₂O₁₄ is an experimental lithium manganese oxysulfide compound with semiconductor properties, belonging to the family of mixed-anion lithium transition metal compounds. This material is primarily investigated in battery and energy storage research, where its unique combination of lithium, manganese, and sulfur-containing phases offers potential advantages in ionic conductivity and electrochemical stability compared to conventional layered oxide cathodes. The dual-anion architecture (oxygen and sulfur) and varied oxidation states of manganese make it a candidate for next-generation solid-state and sulfide-based battery systems, though it remains in early-stage development with limited commercial deployment.
