1. A battery comprising:

  • a plurality of battery cells arranged in a column, and comprising an alternating series of first cells and second cells, each of the cells having a top and bottom side and a left and right side, each cell having a maximum expected peak temperature caused by thermal runaway;

    an insulator in contact with each cell and preventing direct physical contact between each first cell and an adjacent second cell;

    a first thermal bus having a substantially planar portion to the left side of each first cell and a plurality of flanges extending away from the planar portion, each flange coupled to the top of one of the first cells, the first thermal bus constructed of a metal having a melting point higher than the maximum expected peak temperature; and

    a second thermal bus having substantially planar portion to the right side of each second cell and a plurality of flanges extending away from the planar portion, each flange coupled to the top of one of the second cells, the second thermal bus constructed of a metal having a melting point higher than the maximum expected peak temperature.
