Abstract

DC60, a cylindrical cell, was revealed, which was formed in such a way that an insulating ring (12) was positioned on the outside of the sealed portion of the cell shell opening (1). Negative (9) small tracts are pressed under the outer surface. The surface tabs (10) covering the insulating ring (12) and the gas vent (8) formed in the negative electrode (9) are covered by an insulating ring (12). It prevents cells from allowing current flow to adjacent cells. And therefore from being charged by adjacent cells Because the cells use parts on the surface That is an insulator that can shrink heat. It will have improved reliability in Covering Although a number of these cells have the structure described The above is used by being placed in series. And some cells are connected incorrectly. Where the direction of its polarity is reversed with the rest of the cells The possibility of Cells connected in reverse that allow a flow of current to the remaining cells. And therefore will be charged by the remaining cells will be eliminated. And the possibility of The device, when in use, will be contaminated and damaged by the electrolyte, in addition to leakage when the reverse-connected cell is charged, the remaining cells are eliminated. Exposed, which is made up in such a way that the insulating ring (12) is positioned on the outside of the sealed portion of the cell shell opening (1), the negative electrode terminal surface (9) is Pressed under the surface of the surface tab (10), the insulating ring cover (12) and the gas vent (8) formed in the negative electrode (9) are covered with an insulating ring. (12) This structure prevents cells from allowing current flow to adjacent cells and from being charged by adjacent cells. This is because the cell uses an insulating surface component that can shrink heat. It will have improved reliability in the outer covering. Although a number of such cells with the structure described above are used in a series configuration, And some cells are incorrectly connected, where the direction of their polarity is reversed with the rest of the cells, the possibility of reverse-connected cells that allow current flow to The remaining cells and will be charged by the remaining cells are eliminated and the possibility of the device when in use it will be contaminated and damaged by electrolytes. In addition to leakage, when cells that are reverse-connected are charged, the remaining cells are eliminated.
