Summary:A battery pack includes a plurality of cell assemblies each of which include one or more prismatic batteries. A frame has legs sized and configured to be positioned around the prismatic batteries. At least one leg includes a rear face, curved outer edge and a side face. A thermal transfer sheet is made from a sheet of a compressed mass of exfoliated graphite particles.
