A highly conductive Na 3 V 2 (PO 4 ) 3 ceramic sheet prepared by tape-casting method

抄録

Ceramic sheets of Na 3 V 2 (PO 4 ) 3 (NVP) with NASICON-related structure have been prepared by tape-casting method. The addition of 60Na 2 O-10Nb 2 O 5 -30P 2 O 5 glass to NVP is demonstrated to enhance markedly the density of the sintered NVP sheet and its electrical conductivity. The best densified NVP sheet with a thickness of a few tens of μm is obtained by sintering tape-casted NVP added with 5 wt% glass at 920 °C, which exhibits a total conductivity of 2.9 × 10 −5 S cm −1 at room temperature. A Pt | NVP sheet | Pt cell works as a tiny solid-state battery with a cell potential of 1.7 V, in which NVP acts as both cathode and anode active materials via redox reactions of V 4+ /V 3+ and V 3+ /V 2+ as well as a Na + ion conducting electrolyte between the two electrode layers.
