Li2CoCuO4
Li2CoCuO4 is a metastable, semimetallic layered oxide containing lithium, cobalt, copper, and oxygen, primarily investigated for its unique electronic properties in advanced materials research.
About Li2CoCuO4
Li2CoCuO4 is a complex layered lithium transition-metal oxide characterized by its metastable nature and unique electronic structure. As a near-zero-gap material, it exhibits semimetallic behavior that distinguishes it from many traditional insulating oxide counterparts in this class.
This compound is of significant interest in materials science due to its structural complexity and the interplay between its constituent transition metals. Researchers study its behavior to better understand ion transport and electronic conductivity in multi-metal oxide systems, which are critical for the development of next-generation energy storage technologies.
Key Properties

How It Compares
Within the layered lithium transition-metal oxides class.
Within the diverse family of layered lithium transition-metal oxides, Li2CoCuO4 stands out for its semimetallic character, contrasting sharply with the wide-gap insulating behavior typical of stable compounds like LiCoO2 or LiAlO2. While LiCoO2 is a standard benchmark for commercial battery cathodes, Li2CoCuO4 represents a more exotic, metastable configuration that challenges conventional structural paradigms observed in more common members like LiMn2O4.
