Faradaic reactions including charge transfer are often accompanied with diffusion limitation inside the bulk. Conductive two‐dimensional frameworks (2D MOFs) with a fast ion transport can combine both—charge transfer and fast diffusion inside their porous structure. To study remaining diffusion limitations caused by particle morphology, different synthesis routes of Cu‐2,3,6,7,10,11‐hexahydroxytriphenylene (Cu3(HHTP)2), a copper‐based 2D MOF, are used to obtain flake‐ and rod‐like MOF particles. Both morphologies are systematically characterized and evaluated for redox‐active Li+ ion storage. The redox mechanism is investigated by means of X‐ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry and impedance spectroscopy. A significant influence of particle morphology for 2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed. This study opens the path for optimization of redox active porous structures to overcome diffusion limitations of Faradaic processes. [ABSTRACT FROM AUTHOR] |
