Batteries and Supercaps

Over recent decades, rapid advancements in energy technology have transformed human life. Lithium‐ion batteries (LIBs) have played a pivotal role nevertheless concerns about limited lithium resources and price fluctuations underscore the need for sustainability. Sodium‐ion batteries (SIBs), operating on principles akin to LIBs, have emerged as promising candidates for rechargeable batteries in the next generation of energy storage systems, primarily due to their cost‐effectiveness and sustainable attributes. Analogous to LIBs, the cathode in SIBs assumes a critical role in dictating the electrochemical performance of the battery. Therefore, the research and development of cathode materials for SIBs take on paramount significance. O3‐type SIB cathodes, inspired by the successful O3‐type LIB cathodes (e. g., LiCoO2and NMC variants), hold promise for commercial applications. This comprehensive overview offers an in‐depth exploration of various unary‐metal oxide cathode materials characterized by an O3‐layered structure. Subsequently, nickel (Ni), manganese (Mn), and Ni/Mn‐based O3 cathode materials are conducted a comprehensive study, assessing the effects of element substitution and doping on capacity, phase transitions, and cycle life. In light of the current challenges, advancing SIB cathode materials of future directions will propose, addressing key considerations in the pursuit of enhanced performance and sustainable energy storage solutions.

O3‐Type Cathodes for Sodium‐Ion Batteries: Recent Advancements and Future Perspectives

用于钠离子电池的O3型正极材料：最新进展与未来展望

Advanced coatings for improving the electro‐chemo‐mechanical stability of high‐capacity, layered Ni‐rich oxide cathode materials play an important role in modern battery technology. Vanadium‐based protective coatings are particularly promising owing to their ability to provide high ionic conductivity and their intrinsic robustness. In addition, diminishing or eliminating residual lithium through surface coating shows great promise in mitigating capacity losses and addressing associated challenges. Herein, we report on a strategic exploration of a facile coating approach for Ni‐rich LiNixCoyMn1−x−yO2 (NCM851005, 85% Ni content) utilizing polyoxovanadate. Specifically, TBA3H3[V10O28] was applied due to its solubility in non‐aqueous media, avoiding H2O‐induced side reactions and achieving a more uniform surface coverage. The cycling performance of NCM851005 before and after modification was tested in conventional Li‐ion cells, as well as in all‐solid‐state batteries with a lithium thiophosphate superionic electrolyte. Our findings highlight the potential of polyoxovanadate‐derived protective coatings for improving the cyclability of Ni‐rich cathodes.

Polyoxovanadates as Effective Coating Materials for Layered Ni‐rich Oxide Cathodes in Liquid‐ and Solid‐State Batteries

多氧钒酸盐作为液体和固态电池层状富镍氧化物正极的有效涂层材料

Germanium (Ge) is demonstrated to be prospective as a lithium‐ion battery anode material, yet the cycling stability is undermined by substantial volume fluctuations, restricting its viability for practical applications. Here, we present a facile Zn‐based metal−organic framework (MOF) engaged route to produce Ge nanoparticles in situ encapsulated in nitrogen‐doped mesoporous carbon (denoted as Ge@N‐C) as an anode material. This method uses a zinc‐triazolate MOF (MET‐6) and commercial GeO2 as the hybrid carbon and Ge precursors. After a heating treatment, the Ge@N‐C composite is readily obtained along with the simultaneous thermal decomposition of MET‐6 and the reduction of GeO2. Benefiting from the mesoporous structure and high electrical conductivity of N‐C, along with the strong interaction between Ge and N‐C, the obtained Ge@N‐C electrode exhibits a significant reversible charge capacity of 1012.8 mAh g‐1 after 150 cycles at 0.1 A g‐1, and excellent rate capability. Furthermore, a reversible charge capacity of 521.1 mAh g‐1 can be maintained at 5.0 A g‐1 after 1000 cycles.

Abstract NaVPO 4 F has garnered significant attention as a promising cathode material for non‐aqueous sodium‐ion batteries due to its high theoretical specific capacity and appropriate potential. However, the dissolution of vanadium component of NaVPO 4 F in aqueous electrolytes has restricted its application in aqueous sodium‐ion batteries (ASIBs). Herein, we report the use of carbon‐coated NaVPO 4 F as a cathode material in ASIBs. This cathode material exhibited a discharge capacity of 111 mAh g −1 at 0.5 A g −1 in a concentrated 17 m NaClO 4 aqueous solution and demonstrated capacity retention of 74.4 % over 100 cycles. The experimental results confirmed that the carbon coating on NaVPO 4 F and high‐concentration NaClO 4 aqueous electrolyte exhibited positive effects in restraining vanadium dissolution. Additionally, when configuration with NaTi 2 (PO 4 ) 3 @C as anode, the full cell exhibited a capacity of 43.9 mAh g −1 with an average operating voltage of 1.2 V at a current density of 0.5 A g −1 in a concentrated 17 m NaClO 4 aqueous electrolyte. These outcomes underscore the potential of NaVPO 4 F@C as a promising cathode material for ASIBs.

Carbon‐Coated NaVPO<sub>4</sub>F as a High‐Capacity Cathode for Aqueous Sodium‐Ion Battery

碳包覆NaVPO<sub>4</sub>F作为水系钠离子电池的高容量阴极材料

Ionic covalent organic frameworks (iCOFs) have garnered significant attention as potential single‐ion conductive solid‐state electrolytes, where researchers have made great efforts in designing iCOF‐based composites, aiming to improve their intrinsic low conductivity. One successful case is to fill iCOF channels with lithium salts, such as lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). However, the ion transport mechanisms in these composite electrolytes are still largely unknown, hindering their further improvement. Here molecular dynamics simulations were employed to systematically predict the ion diffusivity in iCOF (e.g., TpPa‐SO3Li COF)‐LiTFSI composite electrolytes with varying LiTFSI compositions at different temperatures. A positive correlation was seen between Li+ diffusivity and LiTFSI:iCOF ratio, which was also verified by our experiments. Interestingly, the Li+ diffusion energy barrier obtained by the Arrhenius equation exhibited nearly no dependency on the LiTFSI concentration, indicating the importance of temperature insensitive microstructural related factors. Radial distribution functions show that with a higher LiTFSI proportion, the coordination number of SO3‐ decreases, while that of TFSI‐ increases, suggesting a competition between these two species in the Li+ solvation shell. Furthermore, configurational entropy and bond orientational order parameter calculations examined the degree of disorder in the Li+ solvation structure. These results should improve our mechanistic understandings of iCOF‐based electrolytes.

Atomistic Transport Mechanisms in Lithium Salt‐Doped Ionic Covalent Organic Framework Electrolytes

锂盐掺杂离子共价有机框架电解质中的原子传输机制

Electrodeposition is a popular method for preparing α‐Co(OH)2 as an electrode material for electrochemical energy storage. However, the preparation of technically important β‐Co(OH)2 through electrodeposition remains lacking thus far. Herein, we successfully prepared Co(OH)2 in two phases, α‐ and β‐Co(OH)2, by simply adjusting the electrodeposition potentials, as evidenced by a package of microcopy and spectroscopy analysis. Benefited from a delicate embedding and sectioning technique that may inhibit the loss of interlayer water in microscopy analysis, we find the presence of Co tetrahedron in the interlayer of α‐Co(OH)2 results in a large interlayer spacing of 7.2 Å for the crystal plane (003) compared to β‐Co(OH)2, as well as a higher chemical valence of cobalt in electrodeposited β‐Co(OH)2. The large interlayer spacing creates wider ion channels and more active storage sites for effective energy storage. Consequently, the α‐Co(OH)2 electrode exhibits more competitive electrochemical performance compared to its β counterpart.

Electrodeposition‐Potential Tuning Rejuvenates the Concurrent Preparation from α‐Co(OH)2 with Larger Interlayer‐Spacings to β‐Co(OH)2

电沉积-电位调控使具有较大层间距的α-Co(OH)2同时制备为β-Co(OH)2

The formation of lithium dendrites, driven by the non‐uniform deposition of lithium, remains a critical challenge for the performance and safety of lithium metal batteries. To address this issue, we engineer the surface of copper current collectors by depositing ultra‐thin 2D TiO2 nanosheets with varying thicknesses (0–1200 nm) as a protective layer. Half‐cells without the 2D TiO2 coating exhibit a significant decline in Coulombic efficiency after only 65 charge‐discharge cycles. In contrast, the modified current collector with the smoothest surface achieves remarkable cycling stability, maintaining ~97.6% Coulombic efficiency after 200 cycles. Full cells incorporating these nanosheets demonstrate a good discharge capacity of ~134 mAh/g after 150 cycles at a 1C rate. The improved electrochemical performance is attributed to the high lithium affinity and reduced surface roughness of the current collector facilitated by the 2D TiO2 buffer layer. These findings emphasize the crucial role of 2D TiO2 nanosheets in regulating Li‐ion deposition, thereby significantly improving the cycling stability and performance of lithium metal batteries.

Engineering Current Collector with 2D TiO2 Nanosheets for Stable Lithium Metal Batteries

用于稳定锂金属电池的二维TiO2纳米片工程集流体

Sodium metal batteries (SMBs) have attracted significant attention due to their high theoretical capacity and abundant resources. However, commercialization for this cell is challenged by the high reactivity of sodium metal, leading to detrimental side reactions with electrolytes, dendritic growth, and severe volume changes over charging/discharging cycles. These issues shorten the cycle life, reduce efficiency, and increase the risk of internal short circuits and thermal runaway. A stable solid electrolyte interphase (SEI) is key to addressing these challenges by preventing dendrite growth, homogenizing sodium ion transport, and maintaining chemical stability. This study investigates an artificial SEI(ASEI) composed of polyvinylidene fluoride (PVDF) and ZnF2, which forms a durable organic‐inorganic double‐layer structure. The outer organic PVDF layer enhances mechanical strength, while the inner inorganic ZnF2 layer improves sodium ion flux, preventing dendritic growth. The ASEI significantly extends cell life and enhance electrochemical performances. The NVP||50‐4%+100‐8% PVDF‐ZnF2/Na cell demonstrates stable cycling for over 3000 cycles. This novel ASEI design offers promising potential for improving the energy storage properties and safety of sodium metal batteries.

Artificial Solid‐Electrolyte Interphase with PVDF‐ZnF2 Double‐Layer Structures Enhancing Electrochemical Performance of Sodium Metal Batteries

具有PVDF-ZnF2双层结构的人工固态电解质界面相提升钠金属电池的电化学性能

Olivine LiMnxFe1−xPO4 (LMFP) cathodes are gaining attention as a promising alternative to LiFePO4 (LFP) for lithium‐ion batteries (LIBs), offering higher energy density while maintaining lower costs and improved safety compared to traditional layered oxide cathodes. However, their low electronic conductivity remains a challenge. One effective strategy to enhance electrode kinetics is incorporating carbon additives during fabrication. This study examines the role of conductive additives optimization in LiMn0.7Fe0.3PO4 (LMFP73) electrodes and evaluates the impact of refining the electrode manufacturing to improve performance under practical conditions. Electrodes with 0.5% single‐walled carbon nanotubes (SWCNTs) dispersion demonstrated improved performance. Optimization of mixing protocol, solid content, and coating speed, significantly enhanced the electrode’s microstructure, mechanical integrity, and electrochemical response, producing thick electrodes suitable for industrial use. Upscaling to Graphite|LMFP73 single‐layer pouch (SLP) cells with 200 GSM cathode loading resulted in 110 mAh g⁻¹ at C/2, retaining 93% of the initial capacity after 100 cycles. This work provides practical process parameters to reduce the gap between academic and industrial perspectives in electrode performance assessment under realistic conditions, tackling challenges in performance improvement while taking into account high areal loadings, mechanical properties of the coatings, practical electrode balancing, and electrolyte amount in the cell fabrication process.
