## Description

- description: "Although lithium excess cation-disordered rock salt (DRX) metal oxides
    have been identified as promising candidates for positive-electrode materials,
    their actual potential remains unclear because previous studies have used inappropriate
    technological parameters, such as low mass loadings or excessive amounts of electrolyte.
    In this study, Li2RuO3/Li2SO4 was selected as the model DRX material, and its
    performance was investigated under cell-level high-energy-density conditions.
    A highly-mass-loaded positive electrode (30 mg cm−2) with an active material ratio
    exceeding 96% was fabricated by suppression of the gelation of slurry solution
    during the electrode preparation process, which is achieved by proper control
    of the particle size of Li2RuO3/Li2SO4. Notably, using a protected lithium metal
    electrode setup, superior capacity of the Li2RuO3/Li2SO4 electrode over 180 mA
    h g−1 was achieved over the 80th cycle under high mass loading and lean electrolyte
    conditions. The results obtained in the present study reveal the potential of
    the DRX based positive electrode for realizing superior performance even under
    practical cell conditions.\r\n\r\n"
