Without access to the paper, and only (derivatives of) obfuscating university press releases, the supplementary material [1] allows fumbling together a naive idea of what this is about.
On page 13 a model system is provided with a "SI.6 Thermodynamic Analysis of Ideal Ionocaloric Cycle with Regeneration" diagram to stare at. Alternative substances to ethylene carbonate are described on page 5. Sodium iodide is selected as the salt that is needed in high concentration "to move the phase boundaries".
The mechanism of regeneration seems to be electrodialysis [2], which "is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential difference", a word completely missing in TFA.
There's a nice exploded view of the "Figure SI.10 Electrodialysis Experimental Setup" on page 23, after which the specific Nafion NRE-212 cation exchange membrane [3] and Fujifilm AEM Type 1 anion exchange membrane [4] are listed.
The 2015 article "Present and future caloric refrigeration and heat-pump technologies" [5] is listed as reference, which gives an overview of different "caloric energy conversion" methods and states that "elastocaloric refrigeration represents the most promising alternative, and magnetocaloric refrigeration is a very promising alternative for future applications."
