Earlier work from our lab on nickel-based electrodes – published in Desalination [link] – showed a preference for the intercalation of monovalent ions, so the selectivity can be tuned by choosing the proper transition metal. In the current work qantum-chemical computations were performed to rationalize the selectivity that we found experimentally.
