Abstract

Li_0.4CoO₂ was investigated for its applicability to a potentiometric CO₂ sensor using NASICON (Na⁺ conductor, Na₃Zr₂Si₂PO₁₂) as a solid-reference counter electrode material. Compared with Na_0.6CoCO₂, Li_0.4CoCO₂ was more stable to storage at room temperature as well as to attack by CO₂ at 600°C, as measured for powders or powder attached devices. When coated with a layer of glass, Li _0.4CoO₂ attached-counter electrode allowed the device to generate stable EMF response to CO₂ at 450 °C. These results confirm that Li_0.4CoO₂ can be used as a solid reference counter electrode even more reliable than Na_0.6CoO₂.
