Lead-Based Metal-Organic Framework with Stable Lithium Anodic Performance.

A microporous Pb-based metal-organic framework (MOF) [Pb(4,4'-ocppy)]·7HO (Pb-MOF) has been constructed from 4-(4-carboxyphenyl)pyridine N-oxide and Pb(NO). Structural analysis reveals that the Pb-MOF possesses three-dimensional framework with a one-dimensional rhombic channel. When tested as a lithium-ion battery anode, a reversible lithium storage capacity of 489 mAh g was maintained after 500 cycles at 100 mA g as well as excellent cycling stability.
