## Description

- description: 'LiCoO2 has been used as the cathode material employed in lithium-ion
    batteries since their birth, and efforts to improve its performance are still
    in progress. For example, complete use of lithium provides the theoretical capacity
    as high as 274 mAh g−1; however, charge-discharge cycling with such a high capacity
    leads to rapid degradation. The degradation mechanism has been intensively studied
    in order to increase the practical capacity. Although phase transitions taking
    place in high-voltage charging have been considered to affect the cycling performance,
    side reactions induced by the high-voltage charging always overlap to blur the
    effects of phase transitions on the electrode properties. This study has unveiled
    the relation between the phase transition and electrode properties by employing
    a solid electrolyte that suppresses the side reactions efficiently. Electrochemical
    impedance spectroscopy combined with in-situ X-ray diffraction shows clear correlation
    between phase transition from O3 to H1-3 and drastic increase in the electrode
    resistance. The increasing resistance is attributable to formation of narrow interlayers
    with gallery height of 4.2 Å that impede lithium-ion diffusion. '
