Dereje’s paper, with contributions from Ankit Kumar as well, on evaluating the sodium superionic conductor (NaSICON) frameworks as Ca cathodes, was published today in Chemistry of Materials. The study evaluates the intercalation voltages, theoretical gravimetric capacities, 0 K thermodynamic stabilities, and Ca-migration barriers in silicate, phosphate, and sulfate NaSICON frameworks containing redox-active 3d transition metals. Importantly, our work identified three NaSICON chemistries, namely, Ca_xV₂(PO₄)₃, Ca_xMn₂(SO₄)₃, and Ca_xFe₂(SO₄)₃, to be promising Ca-cathode candidates. The work was led by Prof. Sai Gautam Gopalakrishnan, in collaboration with Prof. Piero Canepa of the National University of Singapore.
