Low‐cost and Non‐flammable Eutectic Electrolytes for Advanced Zn‐I2 Batteries
Publisher: Wiley
Date: 18-08-2023
Abstract: As a burgeoning electrolyte system, eutectic electrolytes based on ZnCl 2 /Zn(CF 3 SO 3 ) 2 /Zn(TFSI) 2 have been widely proposed in advanced Zn‐I 2 batteries however, safety and cost concerns significantly limit their applications. Here, we report new‐type ZnSO 4 ‐based eutectic electrolytes that are both safe and cost‐effective. Their universality is evident in various solvents of polyhydric alcohols, in which multiple −OH groups not only involve in Zn 2+ solvation but also interact with water, resulting in the high stability of electrolytes. Taking propylene glycol‐based hydrated eutectic electrolyte as an ex le, it features significant advantages in non‐flammability and low price that is /200 cost of Zn(CF 3 SO 3 ) 2 /Zn(TFSI) 2 ‐based eutectic electrolytes. Moreover, its effectiveness in confining the shuttle effects of I 2 cathode and side reactions of Zn anodes is evidenced, resulting in Zn‐I 2 cells with high reversibility at 1 C and 91.4 % capacity remaining under 20 C. After scaling up to the pouch cell with a record mass loading of 33.3 mg cm −2 , super‐high‐capacity retention of 96.7 % is achieved after 500 cycles, which exceeds other aqueous counterparts. This work significantly broadens the eutectic electrolyte family for advanced Zn battery design.
The Dynamic Formation from Metal‐Organic Frameworks of High‐Density Platinum Single‐Atom Catalysts with Metal‐Metal Interactions
Publisher: Wiley
Date: 27-10-2022
Abstract: Single‐atom catalysts (SACs) hold great promise for highly efficient heterogeneous catalysis, yet the practical applications require the development of high‐density active sites with flexible geometric structures. The lack of understanding in the dynamic formation process of single atoms in the host framework has been plaguing the controllable synthesis of next generation SACs. Here using Co‐based metal‐organic frameworks (MOFs) as a starting substrate, we fully elucidated the formation of high‐density Pt single atoms with inter‐site interactions in derived Co 3 O 4 host. The cation exchange process and dynamic evolution of Pt−Pt interactions, organic ligand cleavage and Pt‐oxygen coordination formation during the pyrolysis process have been unambiguously interpreted by a series of in situ/ex situ spectroscopic measurements and theoretical computation. These findings would direct the synthesis of high‐density SACs with metal‐metal interactions, which demonstrate significantly enhanced structural flexibility and catalytic properties.
The Application of Hollow Structured Anodes for Sodium‐Ion Batteries: From Simple to Complex Systems
Publisher: Wiley
Date: 04-07-2018
Abstract: Hollow structures exhibit fascinating and important properties for energy-related applications, such as lithium-ion batteries, supercapacitors, and electrocatalysts. Sodium-ion batteries, as analogs of lithium-ion batteries, are considered as promising devices for large-scale electrical energy storage. Inspired by applications of hollow structures as anodes for lithium-ion batteries, the application of these structures in sodium-ion batteries has attracted great attention in recent years. However, due to the difference in lithium and sodium-ion batteries, there are several issues that need to be addressed toward rational design of hollow structured sodium anodes. Herein, this research news article presents the recent developments in the synthesis of hollow structured anodes for sodium-ion batteries. The main strategies for rational design of materials for sodium-ion batteries are presented to provide an overview and perspectives for the future developments of this research area.

Initiating Jahn-Teller Effect in Vanadium Diselenide for High Performance Magnesium-Based Batteries Operated at-40 degrees C
Publisher: Wiley
Date: 12-02-2023
Abstract: Poor electronic and ionic conductivity of electrode materials at low temperatures of −20 °C and below has significantly impeded development of batteries for cold conditions. However, for the first time, layer‐structured metallic vanadium diselenide (1T‐VSe 2 ) is reported as a cathode material for low‐temperature Mg 2+ /Li + hybrid batteries. A high electronic conductivity and fast ion diffusion kinetics for 1T‐VSe 2 are demonstrated at selected temperatures, and a very safe 1T‐VSe 2 /Mg battery for operation at temperatures to −40 °C. The battery exhibits 97% capacity retention over 500 cycles, which is better performance than reported Mg‐based batteries. The Jahn–Teller effect in compressed configuration is initiated in 1T‐VSe 2 with the change of electronic state occurring on electrochemical intercalation of alkali metal ions. Using combined experiment and theory via operando synchrotron X‐ray diffraction, ex situ X‐ray absorption spectroscopy and DFT computation, it is confirmed that the weak Jahn–Teller distortion contributes significantly to fast‐overall kinetics, structural stability, and high electronic conductivity of the electrode. Understanding at an atomic level of the mechanism is demonstrated, that provides valuable guidance in designing high‐performance electrode materials for low‐temperature batteries.

Reversible electrochemical oxidation of sulfur in ionic liquid for high-voltage Al−S batteries
Publisher: Springer Science and Business Media LLC
Date: 29-09-2021
DOI: 10.1038/S41467-021-26056-7
Abstract: Sulfur is an important electrode material in metal−sulfur batteries. It is usually coupled with metal anodes and undergoes electrochemical reduction to form metal sulfides. Herein, we demonstrate, for the first time, the reversible sulfur oxidation process in AlCl 3 /carbamide ionic liquid, where sulfur is electrochemically oxidized by AlCl 4 − to form AlSCl 7 . The sulfur oxidation is: 1) highly reversible with an efficiency of ~94% and 2) workable within a wide range of high potentials. As a result, the Al−S battery based on sulfur oxidation can be cycled steadily around ~1.8 V, which is the highest operation voltage in Al−S batteries. The study of sulfur oxidation process benefits the understanding of sulfur chemistry and provides a valuable inspiration for the design of other high-voltage metal−sulfur batteries, not limited to Al−S configurations.
Reducing Overpotential of Solid‐State Sulfide Conversion in Potassium‐Sulfur Batteries
Publisher: Wiley
Date: 20-04-2023
Abstract: Improving kinetics of solid‐state sulfide conversion in sulfur cathodes can enhance sulfur utilization of metal‐sulfur batteries. However, fundamental understanding of the solid‐state conversion remains to be achieved. Here, taking potassium‐sulfur batteries as a model system, we for the first time report the reducing overpotential of solid‐state sulfide conversion via the meta‐stable S 3 2− intermediates on transition metal single‐atom sulfur hosts. The catalytic sulfur host containing Cu single atoms demonstrates high capacities of 1595 and 1226 mAh g −1 at current densities of 335 and 1675 mA g −1 , respectively, with stable Coulombic efficiency of ≈100 %. Combined spectroscopic characterizations and theoretical computations reveal that the relatively weak Cu‐S bonding results in low overpotential of solid‐state sulfide conversion and high sulfur utilization. The elucidation of solid‐state sulfide conversion mechanism can direct the exploration of highly efficient metal‐sulfur batteries.
Synchrotron X-ray Spectroscopic Investigations of In-Situ-Formed Alloy Anodes for Magnesium Batteries
Publisher: Wiley
Date: 20-01-2022
Abstract: Magnesium batteries present high volumetric energy density and dendrite‐free deposition of Mg, drawing wide attention in energy‐storage devices. However, their further development remains stagnated due to relevant interfacial issues between the Mg anode and the electrolyte and sluggish solid‐state diffusion kinetics of Mg 2+ ions. Herein, an in situ conversion chemistry to construct a nanostructured Bi anode from bismuth selenide driven by Li + is proposed. Through the combination of operando synchrotron X‐ray diffraction, ex situ synchrotron X‐ray absorption spectroscopy, and comprehensive electrochemical tests, it is demonstrated that the nanosize of the in‐situ‐formed Bi crystals contributes to the fast Mg 2+ diffusion kinetics and highly efficient Mg–Bi alloingy/de‐alloying. The resultant Bi anodes exhibit superior long‐term cycling stability with over 600 cycles under a high current density of 1.0 A g ‐1 . This work provides a new approach to construct alloy anode and paves the way for exploring novel electrode materials for magnesium batteries.
Unraveling the Catalyst‐Solvent Interactions in Lean‐Electrolyte Sulfur Reduction Electrocatalysis for Li−S Batteries
Publisher: Wiley
Date: 22-11-2022
Abstract: Efficient catalyst design is important for lean‐electrolyte sulfur reduction in Li−S batteries. However, most of the reported catalysts were focused on catalyst‐polysulfide interactions, and generally exhibit high activity only with a large excess of electrolyte. Herein, we proposed a general rule to boost lean‐electrolyte sulfur reduction by controlling the catalyst‐solvent interactions. As evidenced by synchrotron‐based analysis, in situ spectroscopy and theoretical computations, strong catalyst‐solvent interaction greatly enhances the lean‐electrolyte catalytic activity and battery stability. Benefitting from the strong interaction between solvent and cobalt catalyst, the Li−S battery achieves stable cycling with only 0.22 % capacity decay per cycle with a low electrolyte/sulfur mass ratio of 4.2. The lean‐electrolyte battery delivers 79 % capacity retention compared with the battery with flooded electrolyte, which is the highest among the reported lean‐electrolyte Li−S batteries.
Metal-metal interactions in correlated single-atom catalysts
Publisher: American Association for the Advancement of Science (AAAS)
Date: 29-04-2022
Abstract: Single-atom catalysts (SACs) include a promising family of electrocatalysts with unique geometric structures. Beyond conventional ones with fully isolated metal sites, an emerging class of catalysts with the adjacent metal single atoms exhibiting intersite metal-metal interactions appear in recent years and can be denoted as correlated SACs (C-SACs). This type of catalysts provides more opportunities to achieve substantial structural modification and performance enhancement toward a wider range of electrocatalytic applications. On the basis of a clear identification of metal-metal interactions, this review critically examines the recent research progress in C-SACs. It shows that the control of metal-metal interactions enables regulation of atomic structure, local coordination, and electronic properties of metal single atoms, which facilitate the modulation of electrocatalytic behavior of C-SACs. Last, we outline directions for future work in the design and development of C-SACs, which is indispensable for creating high-performing new SAC architectures.

2D MoN-VN Heterostructure To Regulate Polysulfides for Highly Efficient Lithium-Sulfur Batteries
Publisher: Wiley
Date: 07-11-2018
Abstract: Lithium-sulfur batteries hold promise for next-generation batteries. A problem, however, is rapid capacity fading. Moreover, atomic-level understanding of the chemical interaction between sulfur host and polysulfides is poorly elucidated from a theoretical perspective. Here, a two-dimensional (2D) heterostructured MoN-VN is fabricated and investigated as a new model sulfur host. Theoretical calculations indicate that electronic structure of MoN can be tailored by incorporation of V. This leads to enhanced polysulfides adsorption. Additionally, in situ synchrotron X-ray diffraction and electrochemical measurements reveal effective regulation and utilization of the polysulfides in the MoN-VN. The MoN-VN-based lithium-sulfur batteries have a capacity of 708 mA h g

Studying the Conversion Mechanism to Broaden Cathode Options in Aqueous Zinc‐Ion Batteries
Publisher: Wiley
Date: 21-10-2021
Abstract: Aqueous Zn‐ion batteries (ZIBs) are regarded as alternatives to Li‐ion batteries benefiting from both improved safety and environmental impact. The widespread application of ZIBs, however, is compromised by the lack of high‐performance cathodes. Currently, only the intercalation mechanism is widely reported in aqueous ZIBs, which significantly limits cathode options. Beyond Zn‐ion intercalation, we comprehensively study the conversion mechanism for Zn 2+ storage and its diffusion pathway in a CuI cathode, indicating that CuI occurs a direct conversion reaction without Zn 2+ intercalation due to the high energy barrier for Zn 2+ intercalation and migration. Importantly, this direct conversion reaction mechanism can be readily generalized to other high‐capacity cathodes, such as Cu 2 S (336.7 mA h g −1 ) and Cu 2 O (374.5 mA h g −1 ), indicating its practical universality. Our work enriches the Zn‐ion storage mechanism and significantly broadens the cathode horizons towards next‐generation ZIBs.

A Mo5N6 electrocatalyst for efficient Na2S electrodeposition in room-temperature sodium-sulfur batteries
Publisher: Springer Science and Business Media LLC
Date: 10-12-2021
DOI: 10.1038/S41467-021-27551-7
Abstract: Metal sulfides electrodeposition in sulfur cathodes mitigates the shuttle effect of polysulfides to achieve high Coulombic efficiency in secondary metal-sulfur batteries. However, fundamental understanding of metal sulfides electrodeposition and kinetics mechanism remains limited. Here using room-temperature sodium-sulfur cells as a model system, we report a Mo 5 N 6 cathode material that enables efficient Na 2 S electrodeposition to achieve an initial discharge capacity of 512 mAh g −1 at a specific current of 1 675 mA g −1 , and a final discharge capacity of 186 mAh g −1 after 10,000 cycles. Combined analyses from synchrotron-based spectroscopic characterizations, electrochemical kinetics measurements and density functional theory computations confirm that the high d -band position results in a low Na 2 S 2 dissociation free energy for Mo 5 N 6 . This promotes Na 2 S electrodeposition, and thereby favours long-term cell cycling performance.
