A safety structure for a battery pack assembly includes: an inner layer adapted to be disposed proximate to a plurality of cells of the battery pack assembly, wherein the inner layer defines at least one hollow channel open towards the plurality of cells and configured to vent any of heat, gas, particles, and fire away from selected ones of the plurality of cells; an outer layer adapted to be disposed distal to the plurality of cells of the battery pack assembly; and a resilient layer disposed between the inner layer and the outer layer. The inner layer is a fire-resistant layer comprising a heat-resistant and/or flame-resistant material. The outer layer is a structural layer comprising a substantially rigid material. The resilient layer is adapted to decouple the inner layer from deformation of the outer layer.
