A galvanic cell comprising a molten lithium/lithium-ion electrode and a nitrate electrode has been obtained. It can be represented by the following scheme:
Li(l)/LiNO3(l)/NO2(g), O2(g)/Pt.
Cell formation occurs when the molten lithium nitrate is electrolysed between platinum electrodes. The emf of the cell and its temperature dependence are in good agreement with thermodynamic calculations based on thermal data.
