1. A cell assembly comprising:
a) a plurality of first electrodes, wherein each first electrode comprises a first electrode tab extended therefrom;
b) a solid electrolyte layer comprising a first protrusion; and
c) a second electrode,
wherein the solid electrolyte layer is positioned between one of the plurality of first electrodes and the second electrode, and
wherein the first electrode tab of the one of the plurality of first electrodes contacts another of the plurality of first electrodes, and
wherein the first protrusion of the solid electrolyte layer is positioned, upon folding, to separate the first electrode tab of the one of the plurality of first electrodes from the second electrode to prevent a short circuit therebetween.
