· JVASP-57480· KLiMnO2

KLiMnO₂ is a potassium-lithium manganese oxide ceramic compound belonging to the layered oxide family, primarily investigated as a cathode material for rechargeable battery systems. This material is of significant research interest in energy storage applications due to its potential to combine the electrochemical benefits of lithium and manganese oxides with structural stabilization from potassium, offering advantages in specific capacity and cycling stability compared to conventional single-cation manganese oxide cathodes. Engineers considering this material should note it remains largely in the research and development phase rather than in widespread commercial production.
