Nanoflake Ni-MOF anchored octahedral nickel-porphyrins as a high-performance anode for lithium-ion batteries

Metal-organic framework materials (MOFs) have great potentials as organic electrode materials for lithium-ion batteries due to their amiable porous structure and property tunability. However, the structure instability and poor electrochemical durability of MOFs hinders their application. An interesting metal–organic composite composed of Ni-MOF and Nickel (II)meso-Tetraphenylporphyin (NiTPP) is strategically proposed and configured in this study. The synergic integration of Ni-MOF and NiTPP presents a stable electrochemical cycling performance with a high retention capacity up to 840 mAh/g after 200 cycles, ascribed to the facilitation of the charge transfer capability and the diffusion kinetics. The configured metal–organic composites provide an explorative approach for organic alternatives for nonaqueous metal-ion batteries.
