PURPOSE:To improve cell life by decreasing solubility relating to electrolytic fused carbonate of a positive electrode material LixNi1-xO. CONSTITUTION:A positive/negative electrode, which is a porous gas diffusion electrode, and an electrolyte, interposed between both the electrodes, are provided, and the positive electrode is constituted of an oxide represented by LixNi1-xO(0.05<=x<0.5, preferably, 0.1<=x<0.2). Alkali earth metal carbonate of strontium carbonate or barium carbonate and the like is contained in at least one of the positive electrode and the electrolyte. |
