TiS2/Li10GeP2S12 composite electrodes were fabricated using a mill pot rotator, and their electrochemical properties were investigated with all solid-state batteries of TiS2/Li10GeP2S12/In-Li. The batteries compressed under 19 MPa showed poor cycle stability and low rate capability due to deterioration of physical contact between the TiS2 electrode and the Li10GeP2S12 solid-electrolyte. The battery performance was much improved by applying a pressure of 230 MPa throughout the electrochemical cycling. The battery delivered the reversible capacity of over 160 mAh g−1 with high retention under 1 C operation condition.
