Reversible Metal and Ligand Redox Chemistry in Two-Dimensional Iron–Organic Framework for Sustainable Lithium-Ion Batteries

. Benefiting from the intrinsic robust Fe-N(O) bonds and reinforced Li-N(O) bonds during cycling, Fe-TABQ delivers high capacity retentions over 95% after 200 cycles at various current densities. This work will enlighten more investigations for the molecular designs of advanced MOF-based electrode materials.
