The present application discloses a layer-built cell comprising: a cell assembly formed by putting together a plurality of elemental cells each having thereon a positive terminal and a negative terminal, such that the positive terminals and the negative terminals of the respective elemental cells are located on the same plane; a first insulating plate disposed on the cell assembly and having therein a plurality of through-bores; connecting pieces located on the first insulating plate and passing through the through-bores to connect the elemental cells to one another in series; a second insulating plate disposed on the connecting pieces and having two through-bores; positive and negative lead pieces passing through and projected from the through-bores in the first and second insulating plates; and a terminal plate disposed on the second insulating plate and having thereon a positive external terminal connected to the positive lead piece and a negative external terminal connected to the negative lead piece. Thus, according to the layer-built cell of the present invention, it is possible to prevent undesired electrical connects between the plurality of connecting pieces and the positive and negative lead pieces. Furthermore, according to the present invention, since all elemental cells can be used in the same positional direction, the assembling work may be very simplified. |
