Li4 Co5 Ni1 O12

Li₄Co₅Ni₁O₁₂ is a mixed-metal lithium oxide compound combining cobalt and nickel in a layered oxide structure, belonging to the family of lithium-transition metal oxides. This material is primarily investigated as a cathode active material for lithium-ion batteries, where the mixed cobalt-nickel composition aims to balance energy density, cycle stability, and cost relative to pure cobalt oxide cathodes. The compound is largely in the research and development phase, with potential applications in next-generation battery systems where engineers seek improved volumetric capacity and reduced reliance on pure cobalt.
