Abstract: 
To improve energy efficiency and reduce greenhouse gas emissions, energy storage technologies are of paramount importance. Thermochemical energy storage (TCES) materials offer high energy storage densities, and systems based on the dehydration of common salt hydrates like MgSO₄ · 7 H₂O have been extensively investigated, though frequent problems such as agglomeration and unfavorable kinetics highlight the need for further material development. We consulted our VIENNA TCES-database and became aware of the Tutton salts, M₂M'(SO₄)₂ · 6 H₂O, which have also been previously investigated as TCES materials, although their cycle stability had remained poorly characterized. Herein, we report the synthesis, characterization, and cycle stability of a wide variety of mixed Tutton salts M₂M'₁₋ₓM''ₓ(SO₄)₂ · 6 H₂O.
