  "textContent": "A battery cell including a prismatic cell can housing includes a plurality of walls forming a cell stack receiving zone, one of the plurality of walls including an opening having a first dimension. A vent is positioned across the opening. The vent is configured to open when pressure within the cell stack receiving zone exceeds a predetermined pressure value. An intercell connect board (ICB) is arranged on the one of the plurality of walls. The ICB includes a port that aligns with the opening. A multi-layer vent cover is supported on the ICB. The multi-layer vent cover includes an inner layer supported on the ICB and an outer layer supported on the inner layer. The inner layer includes a first frangible cover and the outer layer including a second frangible cover that is larger than the first frangible cover.",
