Systems and methods for improved battery assemblies for eVTOL aircraft

This disclosure relates generally to an apparatus for organizing battery cells. The apparatus includes a block including: sleeves forming chambers, a first sheet configured to locate the sleeves, and a foam structure surrounding the sleeves. Each chamber is configured to accommodate a battery cell. The block is configured to: organize the battery cells into battery cell groups, separate each battery cell group from its adjacent battery cell groups using a thermally insulating material, and prevent gas from entering into each battery cell group from its adjacent battery cell groups. Each battery cell group includes a plurality of the battery cells, each of the battery cells in the battery cell group is adjacent to at least another of the battery cells in the battery cell group. Each battery cell group is adjacent to at least another battery cell group.
