Systems and Methods for Conducting Battery Heat Using Pouch Cells

摘要

The present disclosure relates to apparatuses for conducting battery heat comprising an active material positioned between a first cover portion and second cover portion, each portion comprising a thermal conductive material and protection material connected to the thermal conductive material. Also included are systems for conducting heat includes a plurality of pouch cells each comprising an active material positioned between a first cover portion and second cover portion and a plurality of frames, at least one frame positioned between each of the plurality of pouch cells. Finally included are methods, for assembling a pouch cell structure for use in conducting battery heat, comprising constructing a pouch cell assembly by alternating a sequence of pouch cells and frames; positioning a first contact edge of each of pouch cell proximal to a first heat sink and a second contact edge of each pouch cells proximal to a second heat sink opposite the first contact edge; and connecting the first heat sink to the first contact edge of each of the plurality of pouch cells and connecting the second heat sink to the second contact edge of each of the plurality of pouch cells.
