Metal‐organic Framework of [Cu₂(BIPA‐TC)(DMA)₂]n: A Promising Anode Material for Lithium‐Ion Battery

Abstract

A copper-based redox-active metal-organic framework (Cu-MOF) is solvothermally synthesized from Cu(NO 3 ) 2 with the ligand 5,5-(1,3,6,8-tetraoxobenzo[Imn] [3,8]phenanthroline-2-7diyl)-bis-1,3-benzenedicarboxylic acid. The as-prepared Cu-MOF is characterized by X-ray diffraction, automatic sphere surface analyzer, field emission scanning electron microscopy, and X-ray photoelectron spectroscopy. The electrochemical properties of Cu-MOF as an anode are investigated for lithium-ion batteries. The Cu-MOF exhibits superior performance including high reversible capacity and excellent cyclic stability. The Cu-MOF shows high initial charge capacity of 753.7 mAh g À 1 , and still remains approximately 53% of its capacity after 500 cycles. In addition, it is revealed that the oxidation/reduction of copper ion in Cu-MOF occurred during charge and discharge process. Figure 8.

Recent advances in process engineering and upcoming applications of metal–organic frameworks

“…Full battery devices constructed with the Cu-CAT NW anode and LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) cathode achieved a high power density of 275 Wh kg −1 . Another copper-based MOF ([Cu 2 (BIPA-TC)(DMA) 2 ] n , denoted as Cu-MOF) showed redox-activity and excellent performance as a LIB anode material [366] . It had a high initial charge capacity of 753.7 mAh g −1 at 0.1 A g −1 and retained 53% of its initial capacity over 500 cycles.…”

Recent Advances in Cu-Based Metal–Organic Frameworks and Their Derivatives for Battery Applications

“…Luo et al used copper nitrate and the H 4 BIPA-TC ligand to synthesize a copper-based [Cu 2 (BIPA-TC) (DMA) 2 ] n MOF. 56 Compared with previous materials, this material has amazing electrochemical performance, and the initial capacity even reached 753.7 mA h g −1 at a current of 0.1 A g −1 . After 500 cycles, the capacity was still about 400 mA h g −1 with a capacity retention rate of 53% (Figure 3g,f).…”

Metal-Organic Frameworks for Metal-Ion Batteries: Towards Scalability

“…This makes it possible to increase the effective anode area without changing the dimensional characteristics of the device, which, in its turn, promises miniaturization of existing batteries. A number of papers [41][42][43][44][45][46][47][48], considering such an approach, demonstrate the achievement of significant results in current densities, charge capacity, and cyclic stability. The mechanism of insertion/extraction of ions is also described in details in [44] using the example of aluminumbased MOF (Fig.…”
