Abstract
A thin battery includes a flat battery body having a positive electrode and a negative electrode having an electrolyte layer disposed between the electrodes. A flexible encapsulating bag seals the battery body with a sealing portion. A positive electrode collector tab and a negative electrode collector tab are respectively connected to the positive and negative electrodes. The tabs penetrate the encapsulating bag. At least one of the tabs includes first and second collector tabs and a safety device so that an electrical connection between the first and second collector tabs may be interrupted when the internal pressure of the encapsulating bag exceeds a predetermined value.
