Special Issue Information

Dear Colleagues,

Widespread application of fossil fuels for energy generation and transportation purposes during the past few decades has dramatically increased the concentration of greenhouse gases in the atmosphere, causing an unprecedented rise in the Earth’s temperature and acidification of the oceans. Therefore, there is an urgent need to reduce the devastating consequences of global warming, as highlighted in the Global Summit on Climate Change (Paris Agreement), as well as the European Commission. Replacing conventional fossil fuels with renewable sources of energy has been recognized as one of the crucial actions required. In this regard, a switch from internal combustion engines (ICE) to electric vehicles (EVs) has recently attracted great attention as the major portion of fossil fuels is consumed for transportation purposes. Meanwhile, transition metal compounds are also rich in physical and chemical properties and widely used in the electrochemical energy storage. They are key materials for chemical power supply, such as lithium/sodium–ion batteries, lithium–sulfur batteries, metal air batteries, supercapacitors, etc. Transition metal compounds are usually of variable valence, composition and structure, involved in complex chemical reactions and structure–activity relationships. Developing their controllable preparatory methods, revealing the laws of physical properties, building battery devices, and achieving high-density energy storage have been the hot spots and focuses of cross-disciplinary research in chemistry, materials, energy and other disciplines. Different surface modification methods, such as atomic layer deposition, chemical vapor deposition, ion beam sputtering, wet chemistry method, solvent casting method, etc., have been used to fabricate high-performance transition metal-based electrodes for electrochemical energy storage.

We are pleased to invite you to contribute original research articles and reviews that will stimulate further research activities in this area and improve our understanding of the key scientific and technological problems in surface modification of advanced transition metal-based materials for electrochemical energy storage. We are particularly interested in articles describing advanced materials with effective surface modifications for energy-storage devices (Li/Na/K/Zn/Mg ion batteries, metal–sulfur batteries, metal-air batteries, supercapacitors) and other transition metal-based electrodes for electrochemical energy storage.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

Advanced electrode materials with surface modifications for Li/Na/K/Zn/Mg-ion batteries and supercapacitors;
Surface-defect-rich nanostructured electrode materials for lithium–sulfur and metal-air batteries;
Novel design and advanced surface modification techniques of electrodes;
Materials analytics, structure characterization and functional evaluation;
Theoretical and experimental understanding of the relationships between structure and performance;
The structure evolution during the electrochemical reactions of the related materials.

We look forward to receiving your contributions.

Abstract

Nickel-element-doped zinc cobaltate/carbon fiber composites (Ni-ZnCo₂O₄/CF) were prepared on carbon cloth (made of a combination of carbon fibers) conductive substrates using a simple ambient stirring method combined with heat treatment. Characterization tests of the materials revealed that the prepared products were porous Ni-ZnCo₂O₄/CF mesh structures. This porous network structure increases the surface area of the material and helps shorten the diffusion path of ions and electrons. The samples were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) methods to investigate the effect of Ni elemental doping on the stability of the materials. The results show that there are no other impurity peaks and no other impurity elements in the Ni-ZnCo₂O₄/CF electrode material, which indicates that the sample purity is high. Meanwhile, the electrochemical properties of Ni-ZnCo₂O₄/CF electrode materials were studied. Under the condition of 15 A·g⁻¹, the specific capacitance of Ni-ZnCo₂O₄/CF electrode material is 1470 F·g⁻¹, and after 100 cycles, its specific capacity reaches 1456 F·g⁻¹, which is 99.0% of the specific capacity of 1470 F·g⁻¹, indicating that the electrode material has good stability. In addition, we assembled asymmetric supercapacitors (Ni-ZnCo₂O₄/CF//CNTs) with Ni-ZnCo₂O₄/CF as the positive material and carbon nanotubes (CNTs) as the negative material. In the cyclic stability experiment of Ni-ZnCo₂O₄/CF/CNTs devices, when the current density was 1 A·g⁻¹, the specific capacitance was 182 F·g⁻¹. After 10,000 cyclic charge–discharge tests, the specific capacity became 167 F·g⁻¹, which was basically unchanged compared with the initial specific capacity, reaching 91.8%. It shows that it has higher charge–discharge performance and higher cycle stability. Full article

Abstract

La-CoMoO₄ was prepared as the electrode material for supercapacitors using the freeze-drying method. The physical and structural properties of the prepared electrode La-CoMoO₄ were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). We further investigated the electrochemical performance of La-CoMoO₄ electrode materials through cyclic voltammetry, constant current charge–discharge, and electrochemical impedance spectroscopy. The research results indicate that compared with CoMoO₄ material (1400 F/g), La-CoMoO₄ material has a high specific capacitance of 2248 F/g at a current density of 1 A/g. In addition, La-CoMoO₄ has a high stability, with a capacitance retention rate of up to 99.2% after 5500 cycles. Finally, supercapacitor devices using La-CoMoO₄ material as the positive electrode have a high energy density of 55 Wh/Kg (power density of 1000 W/Kg), making them a promising electrode material.

Abstract

ZrO₂ is an excellent ceramic preparation material that can maintain chemical stability in medium–strong acid and alkali environments. The sintering impregnation method was used to prepare the ZrO₂/TiO₂/Al₂O₃ composite nanofiltration membrane (ZTA membrane). Nano-ZrO₂, submicron TiO₂, and microporous Al₂O₃ were used as the surface layer, the transition layer, and the support layer, respectively. The structure and phase of the membrane were measured by scanning electron microscopy (SEM) and X-ray diffractometer (XRD). The composite membrane’s retention, hydrophilic and hydrophobic properties were characterized and evaluated using a UV–Vis spectrophotometer, a water contact angle tester (WCA), and a dead-end filtration device. With the increase in separation layer deposition time, the retention rate of methyl blue increased, and the water flux decreased. At a deposition time of 75 min, the retention rate of methyl blue was more than 80%, and the water flux reached 337.5 L·m⁻² h⁻¹ bar⁻¹ at −1 bar transmembrane pressure. The membranes are hydrophilic and have different interception abilities for metal ions, and the order of retention effect is Ag⁺ > Cu²⁺ > Mg²⁺ > Na⁺, and Ag⁺ and Cu²⁺ reached 65.3% and 50.5%, respectively. The prepared ZTA composite nanofiltration membrane has potential application value in heavy metal ion filtration. Full article

Abstract

Aqueous zinc ion batteries (AZIBs) are considered as one of the most promising energy storage technologies due to their advantages of being low in cost, high in safety, and their environmental friendliness. However, dendrite growth and parasitic side reactions on the zinc metal anode during cycling lead to a low coulombic efficiency and an unsatisfactory lifespan, which seriously hinders the further development of AZIBs. In this regard, metal–organic frameworks (MOFs) are deemed as suitable surface modification materials for the Zn anode to deal with the abovementioned problems because of their characteristics of a large specific surface area, high porosity, and excellent tunability. Considering the rapidly growing research enthusiasm for this topic in recent years, herein, we summarize the recent advances in the design, fabrication, and application of MOFs and their derivatives in the surface modification of the zinc metal anode. The relationships between nano/microstructures, synthetic methods of MOF-based materials, and the enhanced electrochemical performance of the zinc metal anode via MOF surface modification are systematically summarized and discussed. Finally, the existing problems and future development of this area are proposed. Full article
