1. An assembly of battery components comprising:
a battery cell stack in which a plurality of battery cells are stacked along a stacking direction,
a first frame member accommodating the battery cell stack and having an open upper portion, and
a second frame member covering the battery cell stack and arranged to extend over the open upper portion of the first frame member,
wherein a surface of the battery cell stack extending parallel to the stacking direction is attached to a bottom portion of the first frame member, the bottom portion being opposite the open upper portion,
wherein a first region of the bottom portion of the first frame member at at least one end of the bottom portion has a step formed therein, the bottom portion including a second region spaced away from the at least one end, wherein the step is defined by a recessed surface of the bottom portion spaced further away from the open upper portion of the first frame member than a surface of the bottom portion in the second region, wherein the battery cells include a protrusion protruding toward and received within the step, and
wherein the first frame member includes an insulating sheet positioned entirely within the step, such that the insulating sheet is arranged to come into contact with the protrusion of the battery cells.
