摘要：

Sulfurized alcohol composite (SAC), a new type of organosulfur material, is applied to an all-solid-state cell with a sulfur-based solid electrolyte (SE), Li3PS4. The cell shows high specific capacity (600-800 mAh g(-1)), and the initial coulomb efficiency is improved by mechanically milling the cathode layer (SAC + SE). The improvement is attributed to the partial lithiation of the SAC sample by milling with SE, which is confirmed by S K-edge X-ray absorption fine structure measurements. Such prelithiation is advantageous for fabricating high-energy-density all-solid-state cells.
