Abstract

Here, a tetrakaidecahedron-shaped Cu four-core supramolecule was designed to overcome the defects of supramolecules for lithium-ion batteries. With multiple metal centers, conductive ligands and abundant hydrogen bonds, this novel electrode shows excellent rate capability (459.4 mA h g⁻¹ at 2000 mA g⁻¹) and cyclicality (494.5 mA h g⁻¹ after 700 cycles).
