Cylindrical battery cell configured with insulation component, and battery module containing the same

A cylindrical battery cell configured for deployment in a battery housing of a battery module that includes a plurality of battery cells, comprising:

• a first end at which both a positive terminal of the cylindrical battery cell and a negative terminal of the cylindrical battery cell are arranged;
• a second end opposite the first end;
• and
• one or more insulation layers integrated into a shaft of the cylindrical battery cell,
• wherein the one or more insulation layers are offset at least from the first end so as to define a first region of the shaft in proximity to the first end that does not include the one or more insulation layers.

A battery module, comprising:

• a set of cylindrical battery cells that each include one or more insulation layers integrated into a shaft of the cylindrical battery cell;
• and
• a battery housing 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 of the given cylindrical battery cell that does not include the one or more insulation layers upon insertion into the battery housing, and
• wherein the battery housing includes at least one insulative housing rib 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.
