A battery module (100; 300), comprises:a set of cylindrical battery cells (2000) that each include one or more insulation layers (2005) integrated into a shaft of the cylindrical battery cell; anda battery housing (2100) into which the set of cylindrical battery cells are inserted, the set of cylindrical battery cells being arranged into a plurality of battery cell groups, each of the battery cell groups including a plurality of cylindrical battery cells connected to each other in parallel, each of the battery cell groups being connected to each other in series;wherein the one or more insulation layers for a given cylindrical battery cell in a first battery cell group that is adjacent to at least one cylindrical battery cell in a second battery cell group is offset from at least one end of the given cylindrical battery cell so as to define at least one region of the shaft of the given cylindrical battery cell in proximity to the at least one end that does not include the one or more insulation layers, wherein the at least one offset is configured to provide at least one exposed portion (2135) of the given cylindrical battery cell that does not include the one or more insulation layers upon insertion into the battery housing, andwherein the battery housing includes at least one insulative housing rib (2125; 2210D; 2215D) arranged between the given cylindrical battery cell and the at least one adjacent cylindrical battery cell that overlaps with the at least one exposed portion to increase electrical insulation between the first and second battery cell groups.
