Abstract:
A method of producing a battery cell structure comprising the steps of:(a) providing a continuous cylindrical thermal sleeve extending between proximal and distal ends and having a longitudinal axis comprised of a plurality of substantially unidirectional longitudinally extending elongated heat conduction fibers being embedded in an adhesive matrix;(b) attaching the thermal sleeve onto the outer peripheral surface of a cylindrical battery cell in a contiguous relationship thereto; and(c) attaching a cylindrical base member having an upstanding annular flange onto the thermal sleeve for reception thereon of the distal ends of the thermal sleeve being contiguous with the upstanding annular flange whereby the upstanding annular flange operates as a heat shunt for drawing heat away from the thermal sleeve by conduction between the heat conduction fibers and the upstanding annular flange.
