Abstract

The invention relates to a button cell and a manufacturing method thereof. The button cell comprises a shell and an electrode isolation assembly arranged in the shell, and the electrode isolation assembly comprises at least one positive electrode and at least one negative electrode; the shell comprises a wall part, at least one protruding part protruding from the surface of the wall part towards or away from the electrode isolation assembly, and at least one lead-out hole respectively penetrating through the wall part and the at least one protruding part; the button cell further comprises at least one electric conductor arranged in the at least one lead-out hole and at least one insulation sealing body arranged between the hole wall of the at least one lead-out hole and the at least one electric conductor, and the at least one electric conductor is electrically connected with the at least one positive electrode or the at least one negative electrode. The positive electrode and the negative electrode of the button cell can be positioned on the same side through the at least one electric conductor arranged on the wall part, so that the space utilization rate is improved; and the at least one insulating sealing body is in interference fit with the at least one lead-out hole, so that the fixing of the at least one insulating sealing body and the sealing of the at least one lead-outhole are realized.

Description

technical field [0001] The invention relates to a battery, more specifically, to a button battery and a manufacturing method thereof. Background technique [0002] Button cells of the related art generally include a case composed of two electrically conductive case halves, a lower case and an upper case, respectively. Usually, the lower shell has positive polarity, the upper shell has negative polarity, and the positive and negative poles are located at the two ends of the button battery. In some applications, when the circuit board needs to be installed, the positive and negative terminals of the circuit board need to be electrically connected to the positive and negative terminals of the button battery respectively, so the negative terminal of the circuit board is drawn from the upper shell, while the positive terminal is drawn from the lower shell. The shell is drawn out and wound along the shell to above the upper shell, and the space utilization rate is low. Contents...
