Battery assembly with high thermal conductivity

A high thermal conductivity battery assembly, comprising:

• a metal case, having a hollow accommodation cavity formed therein;
• a plurality of battery cells, the plurality of battery cells arranged in a first row of battery cells and a second row of battery cells, the first row and the second row installed parallel to one another within the metal case, each of the battery cells having two electrodes with a first electrode of each of the plurality of battery cells in the first row and the second row being connected in a thermally conductive manner to the metal case such that heat generated by each of the plurality of battery cells transfers along an axial direction of the battery cell through the first electrode to the metal case, the first electrode of each of the plurality of battery cells in the first row and the second row connected to the metal case whereby the metal case functions as a common ground;
• a first common electrode extending along a central portion of the hollow accommodation cavity for connection to a second electrode of each of the battery cells, wherein the second electrode of each of the battery cells of the first row are opposed to a first surface of the first common electrode and wherein the second electrode of each of the battery cells of the second row are opposed to a second surface of the first common electrode;
• a second common electrode coupled to a surface of the metal case and the first electrode of each of the plurality of battery cells;
• a thermally conductive flexible gasket having a first surface coupled to the second common electrode and a second surface coupled to the surface of the metal case;
• and
• a fuse device coupled between each second electrode of each of the battery cells and the first common electrode, such that melting a portion of the fuse device isolates a single one of the battery cells.
