An embodiment is directed to a cylindrical battery cell with a multi-terminal cell side that includes an inner cell head and an outer cell rim, with an insulative ring arranged in a recessed area between the outer cell rim and the inner cell head. Another embodiment is directed to a cylindrical battery cell configured with one or more insulation layers integrated into (e.g., wrapped around) a shaft of the cylindrical battery cell. Another embodiment is directed to a battery module including a set of cylindrical battery cells including shaft-integrated insulation, with exposed non-insulated sections of the set of cylindrical battery cells upon insertion into a battery housing being overlapped by one or more insulative housing ribs of the battery housing.
