A vehicle traction battery cell retainer includes a sidewall defining a plurality of windows each surrounded by a window flange extending therefrom, a top channel extending from the sidewall and terminating in a top flange, and a bottom channel extending from the retainer sidewall, defining a plurality of air bypass windows, and terminating in a bottom flange, the top and bottom flanges arranged for interlocking with an adjacent retainer of the traction battery. A vehicle traction battery assembly includes first and second adjacent battery cell arrays each having associated first and second retainers having a sidewall defining air flow windows and integrated top and bottom channels formed of unitary construction with interlocking flanges to couple the first and second arrays.

1. A vehicle traction battery cell retainer, comprising: a sidewall defining a plurality of windows, each surrounded by a window flange extending therefrom,a top channel extending from the sidewall and terminating in a top flange, anda generally U-shaped bottom channel extending from the sidewall, defining a plurality of air bypass windows, and terminating in a bottom flange, the top and bottom flanges arranged for interlocking with an adjacent retainer of a vehicle traction battery. 2. The retainer of claim 1 further comprising a first contoured section between the sidewall and the top flange and a second contoured section between the sidewall and the bottom flange, the first contoured section and the second contoured section adapted to cooperate with edges of a plurality of vehicle traction battery cells. 3. The retainer of claim 1 wherein the sidewall, top channel, and bottom channel are formed from a single material of unitary construction. 4. The retainer of claim 1 wherein the plurality of windows includes windows of alternating shapes. 5. The retainer of claim 1 wherein the top flange comprises at least one tab adapted to interlock with a flange of a neighboring retainer. 6. The retainer of claim 1 further comprising a plurality of integrated reinforcing ribs formed between the top channel and the top flange. 7. The retainer of claim 1 wherein the sidewall, the top channel, and the bottom channel are formed from a single piece of stamped metal. 8. A vehicle traction battery assembly comprising: a first battery cell array having first and second retainers;a second battery cell array positioned adjacent to the first battery cell array and having third and fourth retainers;wherein each of the first, second, third, and fourth retainers includes a sidewall defining air flow windows and having integrated top and bottom channels formed of unitary construction with interlocking flanges to couple the first and second arrays, andwherein each of the bottom channels of the retainers is generally U-shaped and includes at least one air bypass window. 9. The vehicle traction battery assembly of claim 8 wherein each of the air flow windows is surrounded by a flange protruding from the sidewall. 10. The vehicle traction battery assembly of claim 8 wherein the retainers are formed by stamping. 11. The vehicle traction battery assembly of claim 10 further comprising a plurality of integrated reinforcing ribs extending between the interlocking flanges and respective sidewalls. 12. The vehicle traction battery assembly of claim 8 wherein each of the retainers includes a first contoured section between the sidewall and the top channel, a second contoured section between the sidewall and the bottom channel, the first contoured section and the second contoured section cooperating with respective battery cells. 13. A method of assembling a traction battery comprising: connecting battery cells to form an array; andattaching first and second retainers to opposite sides of the array, each retainer comprising a wall that defines a window having a flange, a first flange extending from a first end of the wall, and a second flange extending from an end opposite the first end, the second flange defining a U-shaped channel having an air bypass window. 14. The method of claim 13 further comprising welding a gusset to top and bottom ends of the first and second retainers. 15. The method of claim 14, further comprising: connecting a plurality of cells to form a second array, the second array having a first side and a second side;attaching a third retainer to the first side of the second array;attaching a fourth retainer to the second side of the second array, the third and fourth retainers being the same shape as the first and second retainers; andconnecting the array and the second array.
