Abstract ：
Solid-state lithium batteries (SSLBs) with high safety have emerged to meet the increasing energy density demands of electric vehicles, hybrid electric vehicles, and portable electronic devices. However, the dendrite formation, high interfacial resistance, and deleterious interfacial reactions caused by solid-solid contact between electrode and electrolyte have hindered the commercialization of SSLBs. Thus, in this review, the state-of-the-art developments in the rational design of solid-state electrolyte and their progression toward practical applications are reviewed. First, the origin of interface instability and the sluggish charge carrier transportation in solid-solid interface are presented. Second, various strategies toward stabilizing interfacial stability (reducing interfacial resistance, suppressing lithium dendrites, and side reactions) are summarized from the physical and chemical perspective, including building protective layer, constructing 3D and gradient structures, etc. Finally, the remaining challenges and future development trends of solid-state electrolyte are prospected. This review provides a deep insight into solving the interfacial instability issues and promising solutions to enable practical high-energy-density lithium metal batteries.

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 ：
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 ：
Aqueous zinc-ion batteries (AZIBs) are promising large-scale energy storage devices due to their costeffectiveness and high safety. However, the rampant dendrite growth and notorious side reactions resulting from the decomposition of active water molecules hinder its practical application. Herein, the zincophilic polyoltype surfactant of alkyl polyglycoside (APG) is introduced to induce the rearrangement of the H-bonds network to diminish the free water activity, facilitating the zinc-ion solvation structure transition from [Zn2+(H2O)6 & sdot;SO42-] (solvent separated ion pair, SSIP) to [Zn2+(H2O)5 & sdot;OSO32-] (contact ion pair, CIP) with less Zn2+-solvated H2O. Meanwhile, the APG molecular preferentially adsorb on the Zn surface to form a dehydrated layer, which can suppress the hydrogen evolution reaction (HER) and hinder the two-dimensional (2D) diffusion of Zn2+ ions. Consequently, the Zn//Zn symmetric cell using our designed electrolyte demonstrates an ultralong cycle life of 5250 h at 1.0 mA cm-2/1.0 mAh cm-2. Furthermore, the as-prepared Zn//Na2V6O16 & sdot;3H2O full cell also delivers a high-capacity retention rate of 80.8% even after 1000 cycles at 2.0 A g-1, superior to that of the full cell using pure ZnSO4 electrolyte. This study offers an effective strategy to modulate the cation solvation structure by rearranging the H-bonds network for a highly reversible Zn anode.

Abstract ：
Ionic liquid electrolytes (ILEs) are promising to develop high-safety and high-energy-density lithium-metal batteries (LMBs). Unfortunately, ILEs normally face the challenge of sluggish Li+ transport due to increased ions' clustering caused by Coulombic interactions. Here a type of anion-reinforced solvating ILEs (ASILEs) is discovered, which reduce ions' clustering by enhancing the anion-cation coordination and promoting more anions to enter the internal solvation sheath of Li+ to address this concern. The designed ASILEs, incorporating chlorinated hydrocarbons and two anions, bis(fluorosulfonyl) imide (FSI-) and bis(trifluoromethanesulfonyl) imide (TFSI-), aim to enhance Li+ transport ability, stabilize the interface of the high-nickel cathode material (LiNi0.8Co0.1Mn0.1O2, NCM811), and retain fire-retardant properties. With these ASILEs, the Li/NCM811 cell exhibits high initial specific capacity (203 mAh g-1 at 0.1 C), outstanding capacity retention (81.6% over 500 cycles at 1.0 C), and excellent average Coulombic efficiency (99.9% over 500 cycles at 1.0 C). Furthermore, an Ah-level Li/NCM811 pouch cell achieves a notable energy density of 386 Wh kg-1, indicating the practical feasibility of this electrolyte. This research offers a practical solution and fundamental guidance for the rational design of advanced ILEs, enabling the development of high-safety and high-energy-density LMBs. An anion-reinforced solvating ionic liquid electrolyte is developed to enhance the anion-cation coordination and promote more anions to enter the internal solvation sheath of Li+. This new type of ionic liquid electrolyte improves Li+ transport ability and stabilizes the interface between the electrolyte and high-nickel cathode, rendering the practical application toward high-safety and high-energy-density lithium-metal batteries. 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.

Abstract ：
Iron fluoride (FeF 3 and FeF 2 ) is a potential candidate for the next generation of lithium-ion battery (LIBs) cathode materials due to their high theoretical specific capacity and low cost. However, previous studies have reported that the poor conductivity of FeF 3 and FeF 2 prevents their theoretical specific capacity from being effectively realized. Herein, fluorinated graphene loaded FeF x (FeF x @FG) submicron sphere was synthesized using graphene oxide and utilized as cathode materials for LIBs. Characterization by X-ray diffraction and transmission electron microscopy confirmed that the synthesized FeF x (x = 2 and 3) contains mixed FeF 3 and FeF 2 crystals. The mixed crystal structure enables the FeF x @FG submicron sphere composite to display two steps in the electrochemical reaction when FeF 3 and FeF 2 discharge cooperatively, leading to excellent discharge performance. In addition, since the FG prepared by acid thermal method has good conductivity, it can significantly improve the FeF x conductivity and specific capacity when being connected to FG via C -F bond. The electrochemical tests show that the initial discharge capacity of FeF x @FG is as high as 394.24 mAh/g at the rate of 0.2C in the range of 1.5 - 4.0 V at 25 degrees C and display an excellent discharge capacity retention rate after the first discharge process, showing great potential of the mixed crystalline iron fluoride cathode in the field of lithium-ion batteries.

Abstract ：
Rechargeable metal batteries have received widespread attention due to their high energy density by using pure metal as the anode. However, there are still many fundamental problems that need to be solved before approaching practical applications. The critical ones are low charge/discharge current due to slow ion transport, short cycle lifetime due to poor anode/cathode stability, and unsatisfied battery safety. To tackle these problems, various strategies have been suggested. Among them, electrolyte additive is one of the most widely used strategies. Most of the additives currently studied are soluble, but their reliability is questionable, and they can easily affect the electrochemical process, causing unwanted battery performance decline. On the contrary, insoluble additives with excellent chemical stability, high mechanical strength, and dimensional tunability have attracted considerable research exploration recently. However, there is no timely review on insoluble additives in metal batteries yet. This review summarizes various functions of insoluble additives: ion transport modulation, metal anode protection, cathode amelioration, as well as battery safety enhancement. Future research directions and challenges for insoluble solid additives are also proposed. It is expected this review will stimulate inspiration and arouse extensive studies on further improvement in the overall performance of metal batteries. Highly stable insoluble additives in metal batteries provide a feasible approach to counteract additive depletion as well as its accompanying side reactions. This review summarizes recent advances in insoluble additives for metal batteries with a unique focus on the following aspects: modulation of ion transport, protection of metal anodes, amelioration of cathodes, and enhancement of battery safety. image

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 ：
Hard carbon with abundant resources, low-cost, and high specific capacity, is a promising anode material for large-scale sodium-ion batteries. However, the poor rate performance of hard carbon suffers from serious challenges due to sluggish ion transport dynamic behavior, especially at low potential, in high power density of sodium-ion batteries. To address this issue, we introduce an ionic-conductive sodium-titanate into hard carbon to boost its sodium-ion transport kinetics via constructing a dual ionic-electronic conducting network in hard carbon anode. Benefiting from our design, the optimized hard carbon-sodium titanate electrode achieves high specific capacity of 137 mAh g(-1) at a high current density of 10 A g(-1), compared to that of hard carbon of 25 mAh g(-1) at 10 A g(-1). Remarkably, it also exhibits an excellent capacity retention of 71.4% at the current density of 2.0 A g(-1) after 800 cycles. This work presents a practical strategy for high-rate hard carbon design and provides valuable insights into the construction of high-rate anode for advanced sodium-ion batteries.
