## Description

- description: "The cathode surface of sulfide-based all-solid-state batteries (SBs)
    is\r\ncommonly coated with amorphous-LiNbO3 in order to stabilize\r\ncharge–discharge
    reactions. However, high-voltage charging diminishes the\r\nadvantages, which
    is caused by problems with the amorphous-LiNbO3\r\ncoating layer. This study has
    investigated the degradation of\r\namorphous-LiNbO3 coating layer directly during
    the high-voltage charging of\r\nSBs. O2 generation via Li extraction from the
    amorphous-LiNbO3 coating\r\nlayer is observed using electrochemical gas analysis
    and electrochemical X-ray\r\nphotoelectron spectroscopy. This O2 leads to the
    formation of an oxidative\r\nsolid electrolyte (SE) around the coating layer and
    degrades the battery\r\nperformance. On the other hand, elemental substitution
    (i.e.,\r\namorphous-LiNbxP1-xO3) reduces O2 release, leading to stable high-voltage\r\ncharge–discharge
    reactions of SBs. The results have emphasized that the\r\nsuppression of O2 generation
    is a key factor in improving the energy density\r\nof SBs."
