Insights into the Capacity and Rate Performance of Transition‐Metal Coordination Compounds for Reversible Lithium Storage

Abstract

Coordination compounds are well‐known compounds that are being used as new materials for lithium storage because of their unique advantages, that is, designable structures, abundant active sites, and facile as well as mild synthetic routes. However, the electrode stability, low rate performance, and cycle life of coordination compounds are currently the main issues preventing their application as electrode materials, and the lithium‐storage mechanism in coordination networks is not well understood. Herein, isostructural one‐dimensional coordination compounds were synthesized to study their lithium‐storage performance. Co‐HIPA and Ni‐HIPA showed superior electrolyte stability than other M‐HIPAs, and Co‐HIPA displayed a superior reversible capacity and cycle stability, excellent rate performance, and clear voltage platform. DFT calculations and kinetic analysis revealed the influence of the metal center with different electronic structures on the lithium‐storage mechanism.

In Situ Constructing Coordination Compounds Interphase to Stabilize Zn Metal Anode for High‐Performance Aqueous Zn–SeS2 Batteries

“…Therefore, developing a facile and scalable approach to precisely regulate the anode/ electrolyte interface and suppress side reaction toward stabilized Zn anode is a critical necessity.Coordination compounds, formed by metal centers and organic ligands via coordination bonds, have been applied in numerous fields due to their well-defined compositions and variable structures, abundant active sites, rich functional groups, as well as mild synthetic routes. [18,19] It is worth mentioning that coordination compounds with rich functional groups and ordered open channels exhibits strong affinity for metal ion as well as enable fast and uniform ion flux. [20,21] In addition, coordination bonds can effectively buffer the volume change during charge-discharge processes.…”

High Mass Loading 3D‐Printed Sodium‐Ion Hybrid Capacitors

“…Generally, the potential pseudocapacitive behavior of the electrode has been widely regarded as a superior factor for high‐rate capability and enhanced electrochemical kinetics upon continuous cycling process, which can be quantified by the following analysis (The detailed information is supplied in Supporting Information). [ 18 ] The CV scans were first tested at various scan rates from 0.2–1.2 mV s −1 (Figure S22a, Supporting Information). From that we can obtain the b value (Figure S22b, Supporting Information) of ZnV 2 O 4 NFs@N‐PC in different potentials is 0.78, 1.01, 0.93, 0.86, 0.91, and 0.85, respectively, manifesting its fast surface‐dominated capacitive behaviors.…”

Metal‐organic frameworks and their derivatives as anode material in lithium‐ion batteries: Recent advances towards novel configurations

“…Moreover, the studies on the internal electrochemical mechanism and structural changes being continuously made in this area for further developments. Du et al reported the electrode stability, rate performance, and cycle life for reversible lithium storage of five different one dimensional isostructural MOFs [M(HIPA)(H 2 O) 3 ]n (MHIPAs, M = Mn, Fe, Co, Ni and Zn; H3IPA = 5‐hydroxyisophthalic acid) 39 . The electrode stability based on these five coordination compounds depends upon the metal centre governing the strength of the coordination bonds.…”
