An Efficient and Reversible Battery Anode Electrode Derived from a Lead-Based Metal–Organic Framework

Abstract

Metal−organic frameworks (MOFs) are porous crystalline materials with tailorable structural versatility that were recently considered as one of the most promising alternative anode materials for lithium-ion batteries. Herein, we have synthesized lead-based MOFs (Pb-1,3,5-benzenetricarboxylate, Pb-BTC), which had a high efficiency and reversibe lithium storage for anode material in lithium-ion batteries. The Pb-BTC based battery delivers highly reversible lithium storage capacities of 625 and 450 mA h g −1 at current densities of 0.1 and 0.5 A g −1 , respectively, and can maintain its performance up to 150 charging/discharging cycles. The ex situ X-ray photoelectron spectroscopic studies on the electrode materials at different charging/ discharging states and cyclic intervals reveal that the Li + insertion, conversion, and alloying mechanism play central roles on improving the lithium storage capability. The DFT simulation reveals that the Pb sites in MOFs absorb Li atoms efficiently that support the high storage capacity. The electrochemical performance of Pb-BTC in our work is among the best compared with other reported MOF anode electrodes.

Cesium Lead Halide Perovskite Nanocrystals Assembled in Metal‐Organic Frameworks for Stable Blue Light Emitting Diodes

“…[ 32 ] In this study, we choose Pb‐MOF as the Pb source for perovskite nanocrystal synthesis in order to obtain nanocrystals embedded in the MOF matrix. [ 33 ] Figure illustrates the thin film fabrication process and the structure characterizations for Cs‐PeMOF thin films. As illustrated in Figure 1a, the Pb‐MOF thin film is first spin coated on the substrate and is baked at 100 °C for 30 min.…”

“…The Pb‐MOF material was synthesized follow by the previous reported method. [ 33 ] The Pb(NO 3 ) 2 (10 × 10 −3 m , 50 mL) was dissolved in de‐ionic water and 1,3,5‐H 3 BTC (10 × 10 −3 m , 50 mL) was dissolved in ethanol in two separated beakers, then transfer the Pb(NO 3 ) 2 beaker to ultrasonic bath with slowly added the 1,3,5‐H 3 BTC solution with 30 min of sonication. The white precipitations (Pb‐MOF) were filtered and washed with ethanol before vacuumed dried the solvent residue.…”

Enhancing Capacity and Stability of Anionic MOFs as Electrode Material by Cation Exchange

“…In recent years, different types of MOFs have also been investigated as electrode materials for several energy storage devices, including LIBs and sodium-ion batteries (SIBs), showing promising performance while delivering high capacities (Maiti et al, 2015;Hu et al, 2016;Weng et al, 2020;Baskoro et al, 2021;Feng and Wen, 2021). Many of these compounds incorporate transition metal ions such as Mn(II), Co(II), Ni(II), and Cu(II) (Zhang et al, 2014;Calbo et al, 2019;Wang et al, 2020).…”

A novel flower-like hierarchical aluminum-based MOF anode for high-performance lithium-ion batteries

“…In 2006, Chen et al 22 firstly studied the lithium ion storage performance of MOF-177. Since then, more and more MOFs such as Co 2 (OH) 2 BDC, 23 Tb-MOF, 24 Pb-BTC, 25 Ni-Me 4 BPZ 26 etc. have been reported and directly used as anodes for LIBs, demonstrating that MOFs can be a potential anode material for LIBs.…”
