1. A battery cell assembly, comprising:
a plurality of battery cells;
a bus-bar assembly to which electrode leads of the plurality of battery cells are coupled; and
a barrier interposed between the plurality of battery cells and coupled to the bus-bar assembly,
wherein the barrier is formed of a material including mica,
wherein the bus-bar assembly includes:
a bus-bar frame having a lead hole into which the electrode lead is inserted; and
a support tab protruding from the bus-bar frame toward the battery cells,
wherein an end of the barrier is inserted into the support tab, and
wherein the support tab includes:
a pair of side tabs protruding to oppose both side surfaces of the end of the barrier, respectively; and
a blocking tab opposing at least one of an upper portion and a lower portion of the end of the barrier and configured to connect the pair of side tabs to each other,
wherein the pair of side tabs are formed such that a lower end thereof protrudes further than an upper end from the bus-bar frame in a direction of the at least one of the battery cells,
wherein the upper end and the lower end of the side tab are disposed along a surface of the bus-bar frame, and
wherein the pair of side tabs are spaced apart from each other and form a gap, and a width of the gap of the lower end is greater than a width of the gap of the upper end.
