Abstract :
The successive introduction of silicon (Si) graphite composite anodes into the global market highlights the tremendous commercial potential of Si anodes. Good kinetic performance related to fast charging capability is the central topic of next-generation Si anodes. However, there is a lack of critical reviews exploring the fundamental limiting factors affecting the kinetics of Si and evaluating the effectiveness of the current strategies. In this review, we deconstruct the particle-interface-electrode integration to analyze key limiting factors of kinetics from a practical application perspective for the first time, including long Li+ diffusion distance and poor conductivity for particles, high Li+ migration impedance at the interface, and insufficient or even interrupted Li+ diffusion paths inside the electrodes. Then, the kinetics enhancement strategies for progressively addressing the above issues are systematically investigated and the quantitative relationships between kinetics and these strategies are deeply discussed. Accordingly, the challenges in quantification and balance for fast-charging Si anodes are identified as the remaining issues, and potential solutions are provided. This review provides valuable guidance on fast-charging Si anodes and suggests promising directions in commercial-oriented Si anode studies.

Abstract :
Polyethylene oxide (PEO)-based electrolytes are essential to advance all-solid-state lithium batteries (ASSLBs) with high safety/energy density due to their inherent flexibility and scalability. However, the inefficient Li+ transport in PEO often leads to poor rate performance and diminished stability of the ASSLBs. The regulation of intermolecular H-bonds is regarded as one of the most effective approaches to enable efficient Li+ transport, while the practical performances are hindered by the electrochemical instability of free H-bond donors and the constrained mobility of highly ordered H-bonding structures. To overcome these challenges, we develop a surface-confined disordered H-bond system with stable donor-acceptor interactions to construct a loosened chain segments/ions arrangement in the bulk phase of PEO-based electrolytes, realizing the crystallization inhibition of PEO, weak coordination of Li+ and entrapment of anions, which are conducive to efficient Li+ transport and stable Li+ deposition. The rationally designed LiFePO4-based ASSLB demonstrates a long cycle-life of over 400 cycles at 1.0 C and 65 degrees C with a capacity retention rate of 87.5 %, surpassing most of the currently reported polymer-based ASSLBs. This work highlights the importance of confined disordered H-bonds on Li+ transport in an all-solid-state battery system, paving the way for the future design of polymer-based ASSLBs.

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 :
Hard carbon is a promising candidate for potassium ion batteries due to its large interlayer spacing and abundant closed pores. However, the slow migration and sluggish diffusion kinetics of potassium ions lead to inferior insertion and pore-filling processes, causing severe ion channel blocking, continuous byproduct generation, and poor cycling stability. In this study, we coated hard carbon on top of tetragonal barium titanate particles forming a ferroelectricity-aided anode (t-BTO@C). The t-BTO@C anode exhibits higher interfacial charge density, enhanced insertion-pore filling capacity, and formation of fewer byproducts. The effective interaction between the spontaneous polarization electric field of t-BTO and potassium ions accelerates the potassium ion kinetics and ensures the homogeneous migration of potassium ions, as well as the improvement of t-BTO@C anode potassium storage. After 100 cycles at 0.05 A g-1, the t-BTO@C anode shows a specific capacity of 374.9 mA h g-1, higher than those of SiO2@Carbon (97.2 mA h g-1) and Pure Carbon (240.1 mA h g-1). Paired with a Prussian white cathode, the full cell shows a specific capacity of 313.0 mA h g-1 at 0.1 A g-1, with 88.9% capacity retention after 40 cycles, much higher than those in recent reports. Our strategy provides a new path to improve the performance of the hard carbon anode in potassium ion batteries.

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 :
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 :
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 :
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 :
Considering the growing pre-lithiation demand for high-performance Si-based anodes and consequent additional costs caused by the strict pre-lithiation environment, developing effective and environmentally stable pre-lithiation additives is a challenging research hotspot. Herein, interfacial engineered multifunctional Li13Si4@perfluoropolyether (PFPE)/LiF micro/nanoparticles are proposed as anode pre-lithiation additives, successfully constructed with the hybrid interface on the surface of Li13Si4 through PFPE-induced nucleophilic substitution. The synthesized multifunctional Li13Si4@PFPE/LiF realizes the integration of active Li compensation, long-term chemical structural stability in air, and solid electrolyte interface (SEI) optimization. In particular, the Li13Si4@PFPE/LiF with a high pre-lithiation capacity (1102.4 mAh g-1) is employed in the pre-lithiation Si-based anode, which exhibits a superior initial Coulombic efficiency of 102.6%. Additionally, in situ X-ray diffraction/Raman, density functional theory calculation, and finite element analysis jointly illustrate that PFPE-predominant hybrid interface with modulated abundant highly electronegative F atoms distribution reduces the water adsorption energy and oxidation kinetics of Li13Si4@PFPE/LiF, which delivers a high pre-lithiation capacity retention of 84.39% after exposure to extremely moist air (60% relative humidity). Intriguingly, a LiF-rich mechanically stable bilayer SEI is constructed on anodes through a pre-lithiation-driven regulation for the behavior of electrolyte decomposition. Benefitting from pre-lithiation via multifunctional Li13Si4@PFPE/LiF, the full cell and pouch cell assembled with pre-lithiated anodes operate with long-time stability of 86.5% capacity retention over 200 cycles and superior energy density of 549.9 Wh kg-1, respectively. The universal multifunctional pre-lithiation additives provide enlightenment on promoting large-scale applications of pre-lithiation on commercial high-energy-density and long-cycle-life lithium-ion batteries.

Abstract :
Traditional lithium-ion batteries cannot meet high energy density demands with the popularization of electric vehicles, hybrid electric vehicles, and portable electronics. Thus, novel electrode materials with high theoretical capacity and solid-state electrolytes have been developed. However, they suffer from structural failure and interface instability, limiting their practical application. This review presents the recent advances in liquid metals (LMs) as key electrodes, electrolyte materials, and interface stabilizers for lithium batteries and beyond. First, the typical characteristics of LMs are introduced, including their low melting points, tunable surface properties, high electrical conductivity, self-healing property, and fluidity, showing potential application in next-generation lithium batteries. Subsequently, we focus on the applications of LMs in cathodes, anodes, and electrolytes for lithium batteries and beyond. Finally, the remaining challenges and future opportunities associated with using LMs in high-performance energy storage devices are illustrated.
