Abstract ：
Development of ionic liquid electrolytes (ILEs) plays a key role in achieving high safety and high energy density in lithium metal batteries. While introducing cosolvents can reduce the viscosity of ILEs and enhance Li+ transport ability, the impact of the solvating ability of cosolvents on the solvation structure of ILEs remains unclear. In this work, we rationally design the solvating ILEs, with different solvation abilities of cosolvents, and reveal the correlation between solvation structure and electrochemical performance. We found that introducing cosolvents with moderate solvating ability, such as ethyl acetate (EA), into the ionic liquid electrolyte can regulate the solvation structure of ILEs, thereby optimizing Li+ transport ability and enhancing the stability of the electrode/electrolyte interface. With our designed ionic liquid electrolytes (ILEs), the Li||Ni0.8Co0.1Mn0.1O2 battery cell demonstrates exceptional capacity retention of 84.8% after 800 cycles at 1.0C, significantly outperforming the battery with a conventional ester electrolyte, which retains only 22.1% capacity. This study provides practical solutions and foundational guidance for the rational design of advanced ionic liquid electrolytes and the selection of cosolvents, advancing the development of high-safety and high-energy-density LMBs.

Abstract ：
The development of solid-state electrolytes for Li-metal batteries demands high ionic conductivity, interfacial compatibility, and robust mechanical strength to address lithium dendrite formation and manufacturing challenges. Herein, We report a high-performance SSE, designed via in-situ polymerization of cross-linked poly(vinyl carbonate) (PVC) on a LATSP-coated polypropylene (PP) separator, resulting a LATSP@PP-PVC composite solid electrolyte. The PP separator ensures mechanical strength, while the LATSP coating improves wettability and lithium salt dissociation. Additionally, the cross-linked PVC network restricts TFSI-ion migration, enhancing Li+ conductivity. As a result, the composite exhibits excellent mechanical properties (70 MPa tensile strength, 54 % tensile strain), alongside a room-temperature ionic conductivity (3.19 x 10-4 S cm-1) and a Li+ transference number of 0.468. Li metal batteries employing this SSE paired with LiFePO4 cathodes show 81.56 % capacity retention after 800 cycles at 2 C, demonstrating its potential for commercial solid-state batteries. These findings hold promise for advancing the commercialization of composite electrolytes for solid state batteries.

Abstract ：
Aqueous zinc ion batteries (ZIBs) have been recognized as highly promising energy storage systems due to their high safety, low cost, and environmental benignity. However, low voltage platform of cathode, coupled with uneven Zn deposition, side reactions, and limited operational temperature range caused by free water molecules, has hampered the practical application of ZIBs. To address these issues, 1-ethyl-3-methylimidazolium acetate (EmimAc) ionic liquid (IL) is utilized to modify the active water in polyvinyl alcohol (PVA)-based hydrogel electrolyte. The abundant hydroxyl groups on PVA chains, along with strong interactions between IL and H2O, disrupt hydrogen bonds between water molecules. This hydrogel electrolyte alleviates side reactions, and improves low-temperature performance through suppressing water crystallization and lowering the freezing point of the electrolyte. Furthermore, the strong binding of hydroxyl groups of PVA to Zn2+ restricts Zn2+ migration, ensuring the de-intercalation of Na+ at the Na3V2(PO4)(3) (NVP) cathode, thereby maintaining a high voltage plateau (1.48 V) for improved energy density. Benefitting from these merits, a pouch cell of Zn||NVP achieves 100 cycles at 25 degrees C, and a coin cell achieves 81.3% capacity retention after 1600 cycles at -20 degrees C. This work represents a significant advance in designing expanded work voltage/temperature hydrogel electrolytes for ZIBs.

Abstract ：
Layered oxide cathodes show great promise for commercial applications due to their low cost, high specific capacity, and energy density. However, their rapid capacity decay and slow kinetics primarily caused by harmful phase transitions and a high energy barrier for Na+ diffusion result in inferior battery performance. Herein, we modulate the crystal structure of layered oxide cathodes by replacing the Fe3+ site with Al3+, which strengthens the transition metal layers and enlarges the Na translation layer owing to the smaller ion radius of Al3+ and the stronger bonding energy of Al-O. This restrains the Jahn-Teller effect owing to transition metal dissolution and improves the electrochemical kinetics. Consequently, the modified cathodes exhibited an excellent high-rate performance of 111 mA h g-1 at a high rate of 5.0C and an unexpectedly long cycling life with a 73.88% capacity retention rate after 500 cycles at 5.0C, whereas the bare cathode exhibited a rate performance of 97.3 mA h g-1 with a low capacity retention rate of 48.42% after 500 cycles at 5.0C. This study provides valuable insights into tuning the crystal structure for designing fast charging and highly stable O3-type cathodes.

Abstract ：
Elucidating the microstructure of hard carbon is essential for uncovering the sodium storage mechanism and constructing state-of-the-art hard carbon anodes for sodium-ion batteries. Guided by an understanding of the crystallization process and inverse materials design principles, we design hard carbon anodes with different local fragments to understand the correlation between the microstructure of hard carbon and sodium storage behavior from the commercialization perspective. The sodiation transformation of hard carbon from slope- to plateau-type is realized via a series of local structure rearrangements, including tuning of the interlayer distance, average crystallite width of graphitic domains, and defect density. We found that the increase in plateau capacity is mainly related to the transition from the critical interlayer distance to the average crystallite width of graphitic domain control, and is limited by the closed pore volume of hard carbon. During sodiation, the formation of NaF and Na2O in the slope region, as well as Na2O2 and NaO2 in the plateau region, is always accompanied by the production of Na2CO3. This work provides insights into understanding the sodium storage behavior in hard carbon anodes and defines general structural design principles for transitioning from slope-type to plateau-type hard carbon.

Abstract ：
Sodium-ion batteries (SIBs) with low cost and high safety are considered as an electrochemical energy storage technology suitable for large-scale energy storage. Hard carbon, which is inexpensive and has both high capacity and low sodium storage potential, is regarded as the most promising anode for commercial SIBs. However, the commercialization of hard carbon still faces technical issues of low initial Coulombic efficiency, poor rate performance, and insufficient cycling stability, due to the intrinsically irregular microstructure of hard carbon. To address these challenges, the rational design of the hard carbon microstructure is crucial for achieving high-performance SIBs, via gaining an in-depth understanding of its structure–performance correlations. In this context, our review firstly describes the sodium storage mechanism from the perspective of the hard carbon microstructure's formation. We then summarize the state-of-art development of hard carbon, providing a critical overview of emergence of hard carbon in terms of precursor selection, microstructure design, and electrolyte regulation to optimize strategies for addressing practical problems. Finally, we highlight directions for the future development of hard carbon to achieve the commercialization of high-performance SIBs. We believe this review will serve as basic guidance for the rational design of hard carbon and stimulate more exciting research into other types of energy storage devices. © 2023 The Authors

Abstract ：
The plateau-type sodium titanate with suitable sodiation potential is a promising anode candidate for high safe and high energy density of sodium-ion batteries (SIBs). However, the poor initial Coulombic efficiency (ICE) and cyclic instability of sodium titanate are attributed to the unstable interfacial structure along with the decomposition of electrolytes, resulting in the continuous formation of solid electrolyte interface (SEI) film. To address this issue, a chemical grafting method is developed to fabricate a highly stable interface layer of inert Al2O3 on the sodium titanate anode, rendering the high ICE and excellent cycling stability. Based on theoretical calculations, NaPF6 are more likely adsorption on the Al2O3 surface and produce sodium fluoride. The formation of a thin and dense SEI film with rich sodium fluoride achieves the low interfacial resistances and charge-transfer resistances. Benefitting from our design, the obtained sodium titanate exhibits a high ICE from 67.7 % to 79.4 % and an enhanced reversible capacity from 151 mAh g-1 to 181 mAh g-1 at 20 mA g-1, along with an increase in capacity retention from 56.5 % to 80.6 % after 500 cycles. This work heralds a promising paradigm for rational regulation of interfacial stability to achieve high-performance anodes for SIBs. A chemical grafting method is developed to fabricate a highly stable interface layer of inert Al2O3 on the sodium titanate anode, rendering the high initial Coulombic efficiency (ICE) and excellent cycling stability. This is due to the formation of a thin and dense solid-electrolyte interface (SEI) film with rich sodium fluoride, leading to the lower interfacial resistances and charge-transfer resistances.+ image

Abstract ：
Aqueous zinc-iodine (Zn-I2) batteries have attracted considerable research interest as an alternative energy storage system due to their high specific capacity, intrinsic safety, and low cost. However, the notorious shuttle effect of soluble polyiodides causes severe capacity loss and poor electrochemical reversibility, restricting their practical usage. Herein, this study reports a bifunctional binder (polyacrylonitrile copolymer, as known as LA133) with strong iodine-chemisorption capability for aqueous Zn-I2 batteries to suppress polyiodide shuttling. From both calculation and experimental data, this study reveals that the amide and carboxyl groups in LA133 binder can strongly bond to polyiodides, significantly immobilizing them at cathode side. As a result, fewer byproducts, slower hydrogen evolution, and lesser Zn dendrite in the Zn-I2 battery are observed. Consequently, the battery shows high specific capacity (202.8 mAh g-1) with high iodine utilization efficiency (96.1%), and long cycling lifespan (2700 cycles). At the high mass loading of 7.82 mg cm-2, the battery can still retain 83.3% of its initial capacity after 1000 cycles. The specific capacity based on total cathode slurry mass reaches 71.2 mAh g-1, higher than most of the recent works. The strategy opens a new avenue to address the shuttling challenge of Zn-I2 batteries through bifunctional binder. A new bifunctional LA133 binder with strong iodine-chemisorption capability is reported for high-loading and shuttle-free Zn-I2 batteries. The oxygen-containing groups in LA133 binder can generate strong interactions with I2 and polyiodides, thus significantly enhancing the iodine immobilization performance. This work provides a new strategy to address the shuttling challenge of Zn-I2 batteries from functional binder design. image

Abstract ：
Layered structure Na2Ti3O7 with a suitable sodiation plateau potential (similar to 0.3 V vs Na+/Na) is a promising anode for highly safe sodium-ion batteries (SIBs). However, the practical use of Na2Ti3O7 is hindered by the unstable interface that forms between the anode and electrolyte leading to issues such as low initial coulombic efficiency (ICE) and cycling instability. Herein, we introduce tetraethyl orthosilicate (TEOS) as an electrolyte additive that can spontaneously and effectively react with the main component of the detrimental surface corrosion layer (sodium hydroxide, etc.) to form a protective film on the Na2Ti3O7 anode. The Na2Ti3O7 anode exhibits an enhanced capacity from 134.8 to 167.1 mAh g(-1) at 0.1 A g(-1), along with an increase in capacity retention from 56.1 to 83.9% after 250 cycles at 0.2 A g(-1). This work provides a straightforward protection strategy to address the unstable interface issues, rendering sodium titanate as a promising anode material to achieve practical application in the future.
