A mechanical design of a rechargeable battery cell (e.g., a Lithium-ion battery) disposed inside of a prismatic can, for use in electric vehicles and other electric-powered devices. The improved design uses a thermally conductive insert to divide the battery cell into two adjacent volumes that each hold a pair of stacked layers of a battery cell. This thermally conductive insert conducts heat from the center of the battery cell during battery recharging to actively-cooled channels disposed in a pair of cooling manifolds that are disposed on two vertical sides of the battery cell. Alternatively, or additionally, an actively-cooled bottom cold plate can be used. The pair of stacked battery layers can each be wound in a 'jelly-roll' geometric configuration. The thermally conductive insert may be made of aluminum, aluminum alloy, copper, or copper alloy, and combinations thereof.
