Scalable Precursor-Assisted Synthesis of a High Voltage LiNi_yCo_1-yPO₄ Cathode for Li-Ion Batteries.

ABSTRACT: A solid-solution cathode of LiCoPO₄-LiNiPO₄ was investigated as a potential candidate for use with the Li₄Ti₅O₁₂ (LTO) anode in Li-ion batteries. A pre-synthesized nickel-cobalt hydroxide precursor is mixed with lithium and phosphate sources by wet ball milling, which results in the final product, LiNi_yCo_1-yPO₄ (LNCP) by subsequent heat treatment. Crystal structure and morphology of the product were analyzed by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Its XRD patterns show that LNCP is primarily a single-phase compound and has olivine-type XRD patterns similar to its parent compounds, LiCoPO₄ and LiNiPO₄. Synchr
