1. An energy storage device comprising:
an outer casing lined with a conductive thermal foam; and
a cell assembly comprising at least one cell holder structure and a plurality of energy storage cells held in the cell holder structure, wherein
the plurality of energy storage cells are thermally connected by a phase change material,
the cell assembly are contained within the outer casing;
the conductive thermal foam and the phase change material fill empty spaces within the outer casing in a ratio of 15% to 85%,
the phase change material is between each of the plurality of energy storage cells,
the phase change material is between the cell holder structure and the plurality of energy storage cells,
the conductive thermal foam is between the cell assembly and the outer casing,
the outer casing lined with the conductive thermal foam is configured to provide heat dissipation from the plurality of energy storage cells to the outer casing through the conductive thermal foam,
the conductive thermal foam is configured to prevent leakage of the phase change material from the outer casing when the phase change material melts, and
the phase change material surrounds the plurality of energy storage cells.
