Battery module having thermally conductive adhesive tape for battery cells

Abstract

The present disclosure includes a battery module that includes a housing having a stack of battery cells. Each battery cell of the stack of battery cells includes a terminal end having at least one cell terminal and a face oriented transverse to the terminal end. The battery module also includes adhesive tape disposed between a first face of a first battery cell of the stack of battery cells and a second face of a second battery cell of the stack of battery cells, and where the adhesive tape fixedly couples the first battery cell to the second battery cell, and where a first terminal end of the first battery cell is substantially aligned with a second terminal end of the second battery cell.
