The　extraordinary　thermal-to-electricity　conversion　efficiency　of　thermally　regenerative　electrochemical　cycle　triggers　interest　in　its　reverse　counterpart,　namely　thermally　regenerative　electrochemical　refrigerator　(TRER),　a　promising　alternative　to　conventional　cooling　devices.　Nevertheless,　due　to　three　fundamental　obstacles,　the　practically　feasible　TRER　model　is　still　absent,　which　hinders　the　development　of　follow-up　research.　To　break　this　bottleneck,　heating　by　discharging　and　cooling　by　charging　effects　are　innovatively　utilized　to　construct　TRER　models　where　the　electrochemical　counterparts　of　traditional　adiabatic　compression　and　expansion　processes,　namely　adiabatic　pre-charging　and　pre-discharging　processes,　are　proposed　and　introduced.　Significantly,　the　maximum　coefficient　of　performance　(COP)　and　the　COP　at　maximum　cooling　power　are　predicted　to　achieve　up　to　40%　and　5%　of　Carnot　COP,　respectively　for　the　given　values　of　parameters.　Moreover,　the　great　potential　for　efficient　refrigeration　is　highlighted　by　comparing　the　obtained　results　with　various　refrigeration　systems.　This　work　lays　the　foundation　for　further　experimental　investigations　and　opens　a　new　avenue　for　constructing　other　novel　electrochemical　cycles.　©　2023　Elsevier　Ltd
