1. A rechargeable battery comprising:

  • a plurality of individual sealed battery cells;

    a chassis for containing the battery cells, the chassis including;

    a frame defining an interior space;

    upper and lower fixation plates provided at a top and a bottom, respectively, of the frame and formed of a non-conductive material, the upper fixation plate fastened to the frame;

    an imperforate dielectric separator disposed in the frame and configured to divide the frame interior space into a plurality of openings, the dielectric separator being formed of a fiber composite;

    wherein each opening of the plurality of openings receives an associated, single battery cell and is bounded by the dielectric separator, the frame, and the upper and lower fixation plates; and

    wherein the dielectric separator, the frame, and the upper and lower fixation plates are sized to completely enclose each opening, thereby covering an entire surface area of the single, associated battery cell disposed within each opening to create a complete thermal barrier between adjacent openings and to electrically isolate each battery cell from all other battery cells to prevent current paths between the battery cells.
