“…In recent years, large energy consumption has made scientists and engineers pay greater attention toward electrochemical materials with superior energy density capabilities, long cycle life, and green nature in order to meet the demand for energy storage devices such as in electronics, transportation, and aerospace equipment. − Currently, a large number of ternary metal oxides with a spinel structure are the focus of ongoing research including NiCo 2 O 4 , ZnMn 2 O 4 , NiMn 2 O 4 , and so forth, facilitating the improvement of several properties, such as electronic conductivity, cycle life, and operating voltage due to the synergistic effect between different cations . Among these, ternary ZnMn 2 O 4 with a spinel-like structure has garnered much attention because of its good cost-efficiency, abundance of Zn and Mn active sites, low pollution to environment, and excellent energy density .…”

In recent years, transition metal oxides have been considered as the most promising anode materials due to their high theoretical capacity, low price, and abundant natural reserves. Among them, zinc manganate is used as an electrode material for anodes, whose application is mostly hindered due to its poor ionic/electronic conductivity. In this work, a series of ZnMn 2 O 4 (ZMO) are synthesized by a hydrothermal technique coordinated with a metal−organic framework-based high-temperature calcination process for their application as an anode in lithium-ion batteries (LIBs). Meanwhile, this study systematically explores the influence of carbon doping and the types of organic ligands and oxygen vacancies on the electrochemical properties of the synthesized ZMO. Density functional theory (DFT) calculations and experimental investigations reveal that the introduction of carbon and oxygen vacancies can enhance electronic conductivity, more active sites and faster Li + adsorption, resulting in better electrochemical performances. As expected, all ZMOs with carbon doping (PMA-ZMO, MI-ZMO, and BDC-ZMO) derived from 1,2,4,5benzenetetracarboxylic acid, 2-methylimidazole, and 1,4-dicarboxybenzene achieve outstanding electrochemical performance. Meanwhile, the introduction of oxygen vacancies can enhance the electronic conductivity and can significantly reduce the activation energy of Li + transport, thereby accelerating the Li + diffusion kinetics in the lithiation/delithiation process. Furthermore, an optimal ZMO anode material synthesized by 2-methylimidazole delivers a high reversible capacity of 1174.7 mA h g −1 after 300 cycles at 0.1 A g −1 and 600 mA h g −1 at 0.5 A g −1 after 300 cycles. After high-rate charge and discharge cycles, the specific capacity rapidly recovers to a value greater than the initial value, which proves the unusual activation and thereby an excellent rate property of the electrode. Hence, we conclude that ZMO provides potential application prospects as an anode electrode material for LIBs.

“…[2] In the past ten years, transition metal oxides (TMOs), like nickel (Ni)/cobalt (Co)-based oxides nanomaterials have received widely attention due to the merits of high theoretical capacity and high natural abundance. [3] As a low-oxidized nickel compound, nickel oxide (NiO) stands out and has received tremendous interest in supercapacitor applications owing to its high theoretical specific capacitance (2584 F g À 1 ). [4] For example, Ren et al utilized the electrospinning technique to prepare NiO nanofibers electrodes for supercapacitor applications, which displayed a specific capacitance of 336 F g À 1 at 5 mA cm À 2 .…”

The rational tailoring of micro‐ and mesoporous distribution for porous transition metal oxide‐based nanomaterials is an important factor to control their electrochemistry performances. Herein, flower‐like hierarchical microspheres assembled by ultrathin nickel oxide (NiO) nanosheets were synthesized by a facile solvothermal route and subsequent annealing process. Theoretical analysis and experimental results demonstrate that NiO ultrathin nanosheets prepared by calcination at 450 °C (N‐450) have the optimal micro‐ and mesoporous distribution. The optimal microstructure provides plenty of ion transport channels and abundant active sites. As expected, the N‐450 electrode delivers an ultrahigh specific capacity of 546.53 F g−1 at a current density of 2 A g−1, which is greater than other electrodes. Remarkably, the assembled N‐450//AC asymmetric supercapacitor (ASC) achieves a high energy density of 29.7 Wh kg−1 (at a power density of 800 W kg−1) and exhibits an excellent cycling stability. This work demonstrates an available avenue to enhance the performance of supercapacitor by accurately controlling calcination temperature to adjust the porous architectures of ultrathin NiO nanosheets.
