Abstract

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.
