Li2MnNiO4 is a semiconducting, metastable layered oxide containing lithium, manganese, and nickel, primarily studied for its potential in next-generation battery technologies.
About Li2MnNiO4
Li2MnNiO4 belongs to the class of layered lithium transition-metal oxides, characterized by its semiconducting electronic nature. As a metastable phase, it represents a complex structural arrangement of lithium, manganese, nickel, and oxygen atoms that is of significant interest for understanding ion transport and stability in battery materials. Its structural diversity is highlighted by the numerous reported configurations found across multiple crystallographic databases. This compound serves as a critical subject for researchers investigating the influence of transition metal ordering on the electrochemical performance of cathode materials. By examining its metastable state, scientists can better predict how these oxides evolve during battery cycling and charge-discharge processes.
Key Properties
