About Lithium nickel oxide
LiNiO2 is a prominent member of the layered lithium transition-metal oxide family, characterized by its semiconducting electronic nature. As a thermodynamically stable phase located on the convex hull, it serves as a critical material for high-capacity electrochemical energy storage systems. Its structural integrity and ability to facilitate lithium-ion transport make it a cornerstone of modern battery research. The compound is extensively studied due to its significant role in enhancing the energy density of rechargeable power sources. It is primarily utilized in the development of high-performance cathodes where efficient ion intercalation is essential for long-term cycling stability.
Key Properties
