Zusammenfassung:A sealed secondary battery cell that is chargeable between a charged state and a discharged state is provided. The sealed secondary battery cell comprises a hermetically sealed enclosure comprising a polymer enclosure material, an electrode assembly enclosed by the hermetically sealed enclosure, a set of electrode constraints, and a rated capacity of at least 100 mAmp.hr. A thermal conductivity of the secondary battery cell along a thermally conductive path between the vertically opposing regions of the external vertical surfaces of hermetically sealed enclosure in the vertical direction is at least 2 W/m.K.
