STRUCTURAL UNIT OF BATTERY OF ELECTROCHEMICAL DEVICE AND PROCESS OF ITS MANUFACTURE Russian patent published in 1995 - IPC

FIELD: high-temperature electrochemical devices. SUBSTANCE: structural unit of battery of electrochemical device has discretely placed elements of layer 1 of solid electrolyte produced in the form of granules 2 and means of their binding into monolithic gas-tight layer. Binding means of granules 2 are manufactured from electron-conductive material exhibiting restoring plastic properties in the form of matrix 3 with cells to carry granules 2 arranged in it. Granules are installed in cells of matrix with interference over conjugated surface and have open sections 4 located on one of sides of matrix. There are provided different design variants of manufacture of matrix 3 and granules 2. Process of manufacture of structural unit of battery of electrochemical device includes formation of discrete elements of layer 1 of solid electrolyte from electron-conductive material displaying restoring and plastic properties in the form netted matrix 3 of metal and application of of layer of material of solid electrolyte at least on one surface of matrix 3. This is followed by packing of mentioned layer up to specified thickness with formation of granule-like elements in spaces of cells of matrix 3 and their baking under pressure till gas-tight structure is produced. After baking layer of material of solid electrolyte is removed by one of know methods from one side of matrix up to appearance of matrix surface. Invention provides for other versions of process of manufacture of structural unit. Given structural make of unit realized by described process makes it possible to enhanced its reliability and technology effectiveness with expansion of operational capabilities thanks to increase of thermal and mechanical characteristics of elements of structural unit and provision for use of matrix 3 as means of electric commutation of electrochemical cells of battery and means of independent heating to bring electrochemical device to operating temperature condition. EFFECT: enhanced reliability and technological effectiveness. 36 cl, 7 dwg
