Abstract: Electrochemical cell battery systems and associated methods of operation are provided based on the incorporation of a thermal suppression construct including a supply of an electrically non-conductive hydrofluoroether dispensed directly to and in intimate contact with one or more cells disposed within a sealed enclosure should that one or more cells attain an unsafe thermal state. Excessive heat generated by the one or more cells causes the fluid to boil, generating vapor that removes heat from the one or more cells and ventilates outside of the sealed enclosure through a valve.
