Synthesis and electrochemical performance of solid solution of layered nanostructured LiCo₁ˍₓ Niₓ O₂ (х 0.0, 0.1, ...,0.9) / Kelimah Anak Elong

Layered compounds are being investigated extensively due to their high theoretical specific capacities and relatively good cyclability. Lithium cobalt oxide (LiCoO₂) is an excellent cathode material but expensive and not abundant in nature. LiNiO₂, however, is unstable and do not exhibit good electr...
