PURPOSE:To obtain a cell of a high energy density by using an organic compound, e.g., nephthoquinone, etc., as the positive electrode active material of a cell using an alkali or alkaline earth metal as a negative electrode active material. CONSTITUTION:The stainless steel bottom plate 3 serving as a negative electrode is welded to the bottom of the ceramic ring 1 through the Kovar ring 2. The container is filled with the negative electrode active material 4 of an alkali or alkaline earth metal, e.g., lithium, and then on the active material 4, the positive electrode active material 6 is provided through the separator or solid electrolyte layer 5 impregnated with an electrolyte solution. Then, the container is covered with the stainless steel cover 7 and then airtightly sealed up through the Kovar ring 2' to form a cell. The positive electrode active material 6 used for such a cell includes 1,4- naphtoquinone, 2,6-naphthoquinone, 1,2-naphthoquinone, 1,6-anthraquinone, or the derivatives of these. |
