Large-scale applications of high-capacity silicon-based anodes remain a challenge for high-energy lithium-ion batteries (LIBs) owing to huge volume variation. Although designing nano-sized Silicon (Si) anodes plays a milestone advance in the commercial development, it's still hindered by issues related to cost and side reactions. A simple co-pyrolysis of SiH₄ and C₂H₄ is introduced via chemical-vapor-deposition (CVD) method to prepare SiC_x micro-sized particles with atomic-level homogeneous distributions of silicon and carbon. One basic unit of SiC₄ tetrahedra in SiC_x plays a key role in particles’ microstructure optimization and electrochemical performance improvement: 1) The SiC₄-enriched surface layer is found to hinder Li⁺ insertion. 2) Proper heat-treatment temperature is adopted to eliminate the layer and control the transition from SiC₄ to SiC nanocrystalline, which is significant for decreasing polarization, enhancing Li⁺ diffusion kinetics, and cycling stability. Consequently, the optimized architecture exhibits a high capacity of 1455 mA h g⁻¹ with an outstanding capacity retention of 95.8% after 100 cycles. Pouch-type full-cell demonstrates that the composite possesses excellent cycling stability with capacity retentions of 82.5% after 500 cycles at 25 °C and 84.0% after 400 cycles at 45 °C. This work provides a scalable yet practical solution to micro-sized Si-based anodes.

由于体积差异巨大，高容量硅基阳极的大规模应用仍是高能锂离子电池（LIB）的一大挑战。尽管纳米级硅（Si）阳极的设计在商业开发方面取得了里程碑式的进展，但仍受到成本和副反应等问题的阻碍。通过化学气相沉积（CVD）方法，引入 SiH4 和 C2H4 的简单共热解，制备出硅和碳原子级均匀分布的 SiCx 微型颗粒。SiCx 中的一个基本单元 SiC4 四面体对颗粒微观结构的优化和电化学性能的提高起着关键作用：1) 发现富含 SiC4 的表层阻碍了 Li+ 的插入。2) 采用适当的热处理温度消除该层并控制 SiC4 向 SiC 纳米晶的转变，这对降低极化、提高 Li+ 扩散动力学和循环稳定性具有重要意义。因此，优化后的结构显示出 1455 mA h g-1 的高容量，100 次循环后的容量保持率高达 95.8%。袋式全电池表明，该复合材料具有出色的循环稳定性，在 25 °C 下循环 500 次后容量保持率为 82.5%，在 45 °C 下循环 400 次后容量保持率为 84.0%。这项研究为微型硅基阳极提供了一种可扩展且实用的解决方案。

Photoelectron spectroscopy (PES) studies of solid electrolyte interphases (SEI) of cycled battery electrodes are mostly performed in half cell configurations (i.e., against metallic counter electrodes). In contrast to less reactive Li metal, problems arise in post-Li systems, like K-ion cells, where crosstalk phenomena strongly interfere with the surface layer formation process. This raises the question of whether surface analysis data from half cell experiments are still representative and transferable to corresponding full cells in post-Li systems. Here the major differences between SEI layers formed on graphite electrodes are outlined in K-ion half and full cells derived from an in-depth surface analysis approach combining in-house and (synchrotron-based) hard X-ray PES. This results highlight significant changes in SEI characteristics, both in terms of SEI layer thickness and gradual compositional changes across the interphase, when K-metal (half cell) is replaced by a Prussian white positive electrode (full cell). Furthermore, the initial SEI layers formed on the first cycle are found to evolve and age differently upon further cycling, depending on the two cell configurations. This study stresses the additional complexity of studying post-Li cells and the need to carefully design surface analysis experiments for meaningful material and electrode interphase characterization.

对循环电池电极固态电解质相间层（SEI）的光电子能谱（PES）研究大多在半电池配置（即针对金属对电极）中进行。与反应性较低的锂金属相比，在后锂系统（如 K 离子电池）中出现的问题是串扰现象严重干扰了表面层的形成过程。这就提出了一个问题，即半电池实验中的表面分析数据是否仍具有代表性，并可转移到相应的后锂系统全电池中。在此，结合内部和（同步辐射）硬 X 射线 PES 的深入表面分析方法，概述了在 K 离子半电池和全电池中石墨电极上形成的 SEI 层之间的主要差异。结果表明，当 K 金属（半电池）被普鲁士白正极（全电池）取代时，SEI 特性在 SEI 层厚度和整个相间的渐进成分变化方面都发生了显著变化。此外，根据两种电池配置的不同，在第一个循环中形成的初始 SEI 层在进一步循环中的演变和老化程度也不同。这项研究强调了研究后锂电池的额外复杂性，以及仔细设计表面分析实验以进行有意义的材料和电极相间表征的必要性。

“Anodeless” electrodes for all-solid-state batteries (ASSBs) have been attracting attention as a solution for achieving high energy density. Recent studies on anodeless electrodes have shown improvements in cycle life and energy density through the stabilization of plated lithium (Li) using Li-soluble metals (e.g., Ag, Zn, etc.). In this study, magnesium-based materials (MgF₂@C) are introduced for use as an anodeless electrode. Nanodot magnesium fluoride (MgF₂) is synthesized onto a carbon black surface via sonochemical synthesis. MgF₂ is converted to a Mg-Li alloy and LiF during lithiation. The Mg-Li alloy from the MgF₂@C anodeless electrode reduces lithiation overpotential and provides a uniform and dense Li layer between the current collector and the anodeless electrode. The ASSB cell assembled with the MgF₂@C anodeless electrode exhibits 81.4% capacity retention after 200 cycles at 30 °C.

Aqueous Zn‐ion batteries have emerged as promising candidates for large‐scale energy storage owing to their high safety and low cost. However, dendrite growth and side reactions compromise the stability of the Zn anode in practical applications. Here, a novel Zn anode featuring well‐designed crystal steps along the (002) facets, referred to as Step‐Zn is introduced. The intersections of the (002) and (100) planes in these crystal steps create preferential adsorption sites for Zn2⁺ ions, promoting initial electro‐epitaxial growth of Zn that uniformly covers the crystal steps. This process effectively regulates subsequent Zn deposition, ensuring fast reaction kinetics and smooth morphology without dendrite formation. Consequently, the unique Step‐Zn anode exhibits excellent cycle life over 6000 times at 3 mA cm−2 and low greatly reduced polarization voltage under high areal currents and capacities. Integrated with activated carbon (AC) cathode, the Step‐Zn||AC full cell demonstrates excellent durability over 10 000 cycles at 5 A g−1. This work offers valuable insights into controlling Zn deposition modes by engineering the surface microstructure of Zn anodes with greatly extended cycling stability.

由于安全性高、成本低，锌离子水电池已成为大规模储能的理想候选电池。然而，枝晶生长和副反应影响了锌阳极在实际应用中的稳定性。本文介绍了一种新型锌阳极，它具有沿（002）面精心设计的晶体阶梯，被称为阶梯锌（Step-Zn）。在这些晶阶中，(002) 面和 (100) 面的交点为 Zn2⁺ 离子创造了优先吸附位点，促进了锌的初始电外延生长，使其均匀地覆盖晶阶。这一过程可有效调节后续的锌沉积，确保快速的反应动力学和平滑的形态，而不会形成枝晶。因此，这种独特的阶跃锌阳极在 3 mA cm-2 电流条件下具有超过 6000 次的出色循环寿命，并且在高等电流和高容量条件下极化电压大大降低。Step-Zn||AC 全电池与活性炭（AC）阴极集成后，在 5 A g-1 的条件下可循环使用 10,000 次，表现出卓越的耐用性。这项研究为通过设计锌阳极的表面微结构来控制锌沉积模式提供了宝贵的见解，从而大大提高了循环稳定性。

The lithium–sulfur (Li–S) battery system has attracted considerable attention due to its ultrahigh theoretical energy density and promising applications. However, with the increasing demands on S loading and electrolyte content, practical Li–S batteries still face several serious challenges, such as slow reaction kinetics at the cathode interface, unstable anode interface reactions, and undesirable crosstalk effects between the cathode and anode. Traditional electrolyte systems often struggle to address these challenges under practical conditions, thereby rendering it imperative to establish a new electrolyte system for practical Li–S batteries. This review first discusses the necessity of establishing a new electrolyte and propose specific parameter requirements, such as the electrolyte-to-sulfur mass ratio (E_m/S). Subsequently, some electrolyte modification strategies proposed by researchers are summarized to address the different challenges associated with practical Li–S batteries. Finally, the combination of different strategies is reviewed, aiming to reveal more effective design approaches that simultaneously address multiple challenges, while providing guidance for establishing a new balanced electrolyte for practical Li–S batteries. This article promotes the development of new electrolytes for practical Li–S batteries and can act as a reference for the development of electrolytes for other secondary batteries.

锂硫（Li-S）电池系统因其超高的理论能量密度和广阔的应用前景而备受关注。然而，随着对 S 负载和电解质含量的要求越来越高，实用的锂-S 电池仍然面临着一些严峻的挑战，例如阴极界面反应动力学缓慢、阳极界面反应不稳定以及阴极和阳极之间的不良串扰效应。传统的电解质体系往往难以在实际条件下应对这些挑战，因此为实用锂-S 电池建立新的电解质体系势在必行。本综述首先讨论了建立新型电解质的必要性，并提出了具体的参数要求，如电解质与硫的质量比（Em/S）。随后，总结了研究人员提出的一些电解质改良策略，以应对与实际锂-S 电池相关的不同挑战。最后，对不同策略的组合进行了评述，旨在揭示能同时应对多种挑战的更有效的设计方法，同时为建立实用锂-S 电池的新型平衡电解质提供指导。这篇文章促进了实用锂-S 电池新电解质的开发，并可作为其他二次电池电解质开发的参考。
