a Schematic representation of the MOF synthesis process incorporating various 3d metal ions (Co, Ni, Mn, Fe, Cu, and Zn) with TPDC and BDC ligands. Initial coulombic efficiency (ICE) of 3d metal ion-MOFs with TPDC (b) and BDC (c) ligands plotted against the 1st charge capacity in half-cells. Initial capacity retention (ICR) of 3d metal ion-MOFs with TPDC (d) and BDC (e) ligands plotted against the 5th charge capacity in half-cells. All samples were cycled at a current density of 0.3 mA cm−2.
