1. A battery assembly comprising:
a plurality of battery cells, each battery cell having a generally cylindrical shape, two cell ends, and a cylindrical cell wall extending in an axial direction between the two cell ends, the cylindrical cell wall defining a cell wall surface area;
a plurality of thermal storage devices, each thermal storage device comprising a plastic material, each thermal storage device defining one or more cell receiving spaces for receiving the one or more battery cells, each cell receiving space having a contact surface wherein the contact surface is curved, wherein the contact surface is configured to be in tight contact with a portion of the cylindrical cell wall, and wherein the contact surface comprises the plastic material; and
a lattice arrangement of the battery cells and thermal storage devices, wherein:
an axially extending portion of each cell wall is not in contact with any of the thermal storage devices when the battery cells are inserted into the thermal storage device;
the cell walls of any two neighboring battery cells are not in contact; and
the battery assembly defines air gaps between neighboring thermal storage devices in the lattice arrangement.
