摘要： PURPOSE:To make an accurate detection operable of the life and, with a discharge life prolonged, by enlarging a period of high discharge voltage, in the method of using active materials of more than two kinds with voltage different for anode active material of the cell with a light metal used for the cathode active material. CONSTITUTION:In a cell case 1 is filled an anode active material layer 2, 3, on top of which a cathode active material 5, consisting of light metals like lithium, sodium, etc., is provided through a separator 4. This is sealed by a cell top cover 6 and a gasket 7, to construct a cell of non-water electrolyte. The anode active material layers 2, 3 of this cell is constructed in a layer pattern with the subanode active material layer 2, mainly composed of, for instance, vanadium pentoxide, pressure filled, further with the main anode active material layer 3, mainly composed of manganese dioxide, pressure filled on the former layer. This main active material 3 is selected in a manner with its discharge voltage higher than that of the subactive material 2 and its discharge period becoming longer. In addition to the above, for the main active material 3, molybdenum oxide, tungsten oxide, silver oxide, etc. may be used, and for the subactive material, lead dioxide, silver chromate, silver molybdate, etc. may be used.

摘要： PURPOSE:To provide a battery of high performance small in size further with no leak of electrolyte, by using a solid electrolyte with a rubidium iodide added to a lithium iodide. CONSTITUTION:A solid electrolyte 3, with lithium iodide and rubidium iodide heated in the vacuum to perfectly remove the water of crystallization, thereafter, with a prescribed amount made mixing in the dry box, further with a temperature kept at 600-700 deg.C in argon gas after being fused, is cooled. Subsequently after this product is crushed, the construction is made by pressing at a pressure of 300- 500kg/cm . And this solid electrolyte 3 is put between a negative pole active material 1, with the lithium used, and a positive pole active material 2, with a graphite powder added to a silver iodide, and sealed in a metal case 4 to construct the battery. In such way, by means of adding rubidium iodide to lithium iodide, a conductivity can be improved capable of obtaining a battery small in size with high performance.
