Manganese-Resorcin[4]Arene-Based Metal-Organic Framework: Syntheses, Structure and Lithium-Ion Battery Application

Abstract

By employing a dodecarboxylic acid substituted resorcin[4]arene ligand (L), a new metal-organic framework (MOF), [Mn₆(L)(H₂O)₁₄] ⋅ DMA ⋅ 5H₂O (defined as Mn-L) has been synthesized under solvothermal conditions. Mn-L shows a 3D framework with abundant carboxyl groups, which result in the excellent electrochemical performance as anode materials in lithium ion batteries (LIBs). The activated Mn-L maintains the specific capacities of 598 mAh/g at 200 mA/g after 150 runs and 420 mAh/g at 500 mA/g after 350 runs. The excellent rate capacity, cyclic stability enable Mn-L to be prospective anode material for LIBs.
