Folding sheet button cell

Abstract

The utility model discloses a folding sheet button cell, which comprises a ceramic shell and an insulation isolation sealing structure arranged at the opening of the ceramic shell, the ceramic shell and the insulation isolation sealing structure are enclosed to form a mounting cavity, a folding cell sheet is arranged in the mounting cavity, the folding cell sheet comprises a substrate, the substrate comprises an isolation film, and the isolation film is arranged in the mounting cavity. One side surface of the isolation film is provided with an anode film, and the other side surface of the isolation film is provided with a cathode film; the substrate is bent towards one side of the positive electrode film to form a first bent part and is bent towards one side of the negative electrode film to form a second bent part; a positive terminal and a negative terminal are embedded in the ceramic shell at intervals, the positive terminal is conductively connected with the first bending part, and the negative terminal is conductively connected with the second bending part; a control circuit PCB located on the outer side of the insulation isolation sealing structure is installed on the ceramic shell, and the positive terminal and the negative terminal are electrically connected with the control circuit PCB. The folding thickness is effectively reduced; and the internal resistance is reduced.
