Original Abstract Submitted

A battery module includes: positive and negative terminals disposed on an exterior of a housing of the battery module; groups of cylindrical battery cells, each of the battery cells of each group having a positive and negative terminals, and a vent; and electrically conductive busbars that electrically connect the groups, that electrically connect positive terminals of the battery cells of a first one of the groups with the positive terminal of the battery module, and that electrically connect negative terminals of the battery cells of a second one of the groups with the negative terminal of the battery module; and a thermal runaway protection blanket including: a first surface; a second surface opposite the first surface; and recessed portions that are recessed relative to the second surface and that extend toward the first surface, where the vents of at least a portion of the battery cells face the recessed portions.
