Abstract: A battery cell stack assembly for a prismatic battery includes a plurality of monocells and two current collector bracket assemblies. Each monocell includes an anode electrode sheet having an outer perimeter and an anode cell tab and a cathode electrode sheet having a cathode cell tab. One of the current collector bracket assemblies electrically connect each of the anode cell tabs with one another and a remaining current collector bracket assembly electrically connects each of the cathode cell tabs with one another, and each current collect bracket assembly includes at least one arm that is positioned to electrically connect either two or more of the anode cell tabs or two or more of the cathode cell tabs to one another.
