Abstract
A system includes a first battery cell, a second battery cell, and thermally conductive material that couples to the battery cells. In turn, the thermally conductive material dissipates heat between the first battery cell and the second battery cell, thus reducing a temperature differential between the first battery cell and the second battery cell.
