摘要： PURPOSE:To reduce the deterioration of a light emitting layer due to permeating moisture and obtain a long life by erecting the outer periphery of a back elec trode to a transparent electrode side, and erecting the outer periphery of a water capturing layer on the back electrode side to the transparent electrode side. CONSTITUTION:The outer periphery 6a of a back electrode 6 is erected to a transparent electrode 1 side, and the outer periphery 8a of a water capturing layer 8 on the back electrode 6 side is erected to the transparent electrode 1 side. The moisture permeating the adhesive layers 9a and 10a of moisture- proof films 9 and 10 and infiltrating into an element is captured by the outer periphery 8a of the water capturing layer 8 erected to the transparent electrode 1 side, and moisture is prevented from reaching a light emitting layer 4.

摘要： PURPOSE:To eliminate shortcircuiting even in case a current collecting network is in direct contact with a separator, which is to separate a negative electrode from a positive, by arranging an insulation sheet below the center of the separator, and thereby decreasing the thickness of the battery concerned. CONSTITUTION:A separator 3 is to separate a negative electrode 1 from a positive 2. The central part of a current collecting network 10 is welded to the lower part of a terminal 9. An insulation sheet 12 is arranged below the central part of this separator 3. This prevents generation of shortcircuit even though the battery has a small thickness and the electrode arranged on the battery lid 6 side is made in the form of a ring, which requires the current collecting network 10 to be in direct contact with the separator 3.

摘要： PURPOSE:To obtain a flat sealed battery capable of the long term usage and having the high sealability by pressing-in a revet shaped sealing body, which consists of a shank and a head part having a diameter larger than that of the shank, in an electrolyte filler hole of a battery vessel, and welding the outer peripheral part of the head part to the bottom part of the battery vessel. CONSTITUTION:A cylindrical or taper tubelous electrolyte filler hole 12 is provided at the center of a bottom part 5a of a battery vessel 5, and after the filling of the electrolyte, a shank 13 of a sealing body 13 is pressed-in the electrolyte filler hole 12. Under the condition that the electrolyte filler hole 12 is sealed by the shank 13a of the sealing body 13, the outer poripheral part of a head part 13b of the sealing body 13 is welded to the bottom part 5a of the battery vessel 5. Thereby, at the time of welding of the head part 13b of the sealing body 13 to the bottom part 5a of the vessel part 5, the vaporized material is not leaked out to the part to be welded so as to enable the secure welding without a pin hole, the electrolyte filler hole 12 is perfectly sealed and the battery having the high sealability can be thus obtained.

摘要： PURPOSE:To improve the pulse closed-circuit voltage property, by furnishing a lithium alloy layer at the side opposing to a separator of a lithium layer of a negative electrode, and making the space rate of a positive electrode at a specific value. CONSTITUTION:In a lithium cell with a negative electrode active substance of lithium and a positive electrode active substance of a mixture of iron sulfide and copper oxide, is furnished a lithium alloy layer 3b, which consists of a lithium alloy made electrochemically from lithium and a metal to be alloyed with lithium electrochemically, at the side opposing to a separator 4 of a lithium layer 3a of a negative electrode 3, and moreover, the space rate of a positive electrode 1 is made 40 to 57 volume%. The pulse closed-circuit voltage property of a cell increases the reaction area of the negative electrode 3 side, and when the polarization of the negative electrode 3 side is reduced, then, the pulse closed-circuit voltage property is controlled by the polarization of the positive electrode side. Therefore, the pulse closedcircuit voltage property is made to improve by converting the space rate of the positive electrode 1.

摘要： PURPOSE:To obtain a sharp display having a high coloring density by forming a metallic plating layer on the transparent conductive film in the lead terminal attaching part of a display electrode substrate without staining the content in an electrochromic display element in the stage of the parts of said element. CONSTITUTION:A protective film 8 consisting of an SiO2 film is formed by forming the transparent conductive film 1b consisting of ITO on a transparent glass substrate 1a, patterning the same to form the display electrode substrate 1 and masking 31 the peripheral edge thereof. After the mask 31 is removed, a photoresist film 32 is formed on a protective film 8 and a mask 33 consisting of a self-adhesive tape is disposed thereto; thereafter, a plating layer 5 is formed on the transparent conductive film 1b in the peripheral edge part of the display electrode substrate 1. Since plating is executed in the stage before the formation of the electrochromic material layer 7 on the display electrode substrate 1, the staining of the electrochromic material by a plating bath and resist film is obviated.
