THIN, SEALED LEAD-ACID BATTERY

摘要

PURPOSE:To provide a thin, sealed lead-acid battery having high reliability in a soldered part and capable of using in an environment where temperature change is remarkably large. CONSTITUTION:A plurality of cells 1 are arranged in the flat direction on a circuit board 2. The arranged part of each cell 1 on the circuit board 2 is formed as a space 3 except for the periphery of the cell 1. The periphery of the space 3 on the circuit board 2 is used as a cell supporting frame 2a and a cell-to-cell connecting frame 2b. A cell terminal connecting pattern layer 4a in which cathode cell terminals of the cells 1 are connected with a soldered part 6a and cell terminal connecting pattern layer 4b in which anode cell terminals 1b are connected with a soldered part 6b are installed at a distance of an insulating spacing part 5 in the cell-to-cell connecting frame 2b. A slit 7 which separates the soldered part 6a of the cathode cell terminal 1a from the soldered part 6b of the anode cell terminal 1b is installed in the insulating spacing part 5 in the cell-to-cell connecting frame 2b. By the slit 7, the stress is relaxed.
