· JVASP-55805· LiMnAsO4

LiMnAsO4 is an inorganic ceramic compound containing lithium, manganese, arsenic, and oxygen, belonging to the family of mixed-metal oxides with potential electrochemical functionality. This material is primarily of research interest as a candidate lithium-ion battery cathode material, where the manganese and arsenic oxidation states can support lithium insertion/extraction cycles. While not yet widely deployed in commercial products due to arsenic toxicity concerns and performance trade-offs versus established alternatives like LiCoO₂ or LiFePO₄, it represents exploration within the broader class of polyanion-based battery materials that offer structural stability and cost advantages in specialized energy storage applications.
