Li2 Ru2 O4

Li₂Ru₂O₄ is a mixed-valence lithium ruthenate ceramic compound that combines lithium and ruthenium oxides in a layered crystal structure, belonging to the family of functional oxides with potential electrochemical activity. This material is primarily of research interest for energy storage and catalytic applications, particularly in lithium-ion battery systems and electrocatalysis where the ruthenium redox activity and lithium mobility are exploited; it represents an experimental composition within the broader class of lithium transition-metal oxides that engineers explore when designing high-capacity anodes, cathodes, or oxygen evolution catalysts beyond conventional materials.
