Abstract
Electrochemical cell battery systems and associated methods of operation are provided based on the incorporation of a thermal management matrix including a supply of phase change material disposed at least in part in a heat conductive lattice member to effectively dissipate heat produced or generated by or in the battery system such as to minimize or prevent thermal runaway propagation in the electrochemical cells of the system.
