Original Abstract Submitted

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.
