## Description

- description: The origin causing detrimental phase transition in LiNiO2 is discussed
    through the detailed analysis on LiNiO2 integrated with nanosized Li3PO4, which
    is derived from a metastable and rocksalt LiNiO2–Li3PO4 solid solution sample.  LiNiO2
    derived from the metastable rocksalt oxide has approximately 6% anti-site defects
    between Li and Ni sites, and the particle size growth is suppressed by the presence
    of uniformly dispersed nanosized Li3PO4.  In low crystallinity LiNiO2 with partial
    structural disordering derived from the rocksalt precursor, the Ni ion migration
    to tetrahedral sites is effectively suppressed because of repulsive electrostatic
    interaction from Ni ions located in Li layers.  Moreover, on the basis of these
    findings, non-stoichiometric LiyNiO2 has been directly synthesized without high-energy
    milling and Li3PO4 integration, and significant improvement of electrode reversibility
    is achieved for the non-stoichiometric oxide without the addition of non-nickel
    ions.  The unified understanding of deterioration mechanisms for LiNiO2 offers
    a new criterion to design Co-free LiNiO2 without metal substitution, potentially
    leading to full utilization of a reversible capacity as layered materials.
