N2 - All-solid-state phosphate symmetric cells using Li3V 2(PO4)3 for both the positive and negative electrodes with the phosphate Li1.5Al0.5Ge 1.5(PO4)3 as the solid electrolyte were proposed. Amorphous Li1.5Al0.5Ge1.5(PO 4)3 was added into the electrode to increase the interface area between the active materials and the electrolyte. Any other phases were not formed at the electrode/electrolyte interface even after hot pressing at 600 °C. The discharge capacity was 92 mAh g-1 at 22 μA cm -2 at 80 °C, and 38 mAh g-1 at 25 °C, respectively. Symmetric cell configuration leads to simplify the fabrication process for all-solid-state batteries and will reduce manufacturing costs.
