THIN BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a thin battery which can reduce aspect dimension of the battery and contain a laminated electrode in an armor case made of a resin film-based laminate sheet without dead space. SOLUTION: A thin laminated electrode 4 in which a film-like or sheet-like positive electrode plate 1, a separator 3 and a negative electrode plate 2 are integrally laminated is mounted on one side of a resin film-based laminate sheet constituting an armor case 7 to be contained in electrodes containing recessed part 11 corresponding to the electrode 4. The electrode 4 is sealed in the case 7 by heat-welding the periphery where one side and another side of the laminate sheet are overlapped.
