Hard carbon has emerged as a promising anode material for sodium-ion batteries (SIBs) due to its exceptional chemical stability and abundant resources. However, its application in energy storage is limited by the poor fast-charging performance caused by the slow Na⁺ reaction kinetics. Herein, thiophene-S doped oxidized pitch (SOP-600) with outstanding fast-charging performance has been fabricated via a facile ball milling and carbonization procedure. Benefiting from the high thiophene-S doping content, the optimized SOP samples (SOP-600) exhibit plentiful active sites and a rich micro-mesoporous structure with rapid ion transport channels, significantly enhancing the Na⁺ reaction kinetics and improving the fast-charging performance. When employed as SIBs anode, SOP-600 delivers an impressive specific capacity of 690.3 mAh g⁻¹ at 0.05 A g⁻¹. In addition, it maintains a significant reversible capacity of 373.5 mAh g⁻¹ at 7 A g⁻¹ with a capacity retention rate of 54.1%, demonstrating excellent fast-charging performance. Moreover, SOP-600 anode exhibits a remarkable cycling capacity of 490.7 mAh g⁻¹ under 1 A g⁻¹, with 92.5% capacity retention after 1000 cycles, highlighting its robust structural stability. Furthermore, sodium ion hybrid capacitors (SICs) assembled with SOP-600 anode and activated carbon cathode achieve a high reversible capacity of 53.5 mAh g⁻¹ at 1 A g⁻¹. This work provides theoretical insights into how thiophene-S doping enhances the fast-charging performance of hard carbon in SIBs.

硬碳因其优异的化学稳定性和丰富的资源而成为一种很有前途的钠离子电池负极材料。然而，由于Na+反应动力学缓慢，其快速充电性能较差，限制了其在储能领域的应用。本文通过简单的球磨和碳化工艺制备了具有优异快速充电性能的噻吩- s掺杂氧化沥青（SOP-600）。优化后的SOP-600样品具有丰富的活性位点和丰富的微介孔结构，具有快速离子传输通道，显著增强了Na+反应动力学，提高了快速充电性能。当用作sib阳极时，op -600在0.05 A g−1时提供了令人印象深刻的690.3 mAh g−1比容量。此外，在7 a g−1时，它保持了373.5 mAh g−1的显著可逆容量，容量保持率为54.1%，表现出优异的快速充电性能。此外，op -600阳极在1 a g−1下的循环容量为490.7 mAh g−1，循环1000次后容量保持率为92.5%，突出了其强大的结构稳定性。此外，由op -600阳极和活性炭阴极组装的钠离子混合电容器（sic）在1a g - 1下可获得53.5 mAh g - 1的高可逆容量。这项工作为噻吩- s掺杂如何增强sib中硬碳的快速充电性能提供了理论见解。

The oxygen evolution reaction (OER) is a key process in water splitting for hydrogen production, yet its sluggish kinetics pose significant challenges for catalyst development. In this work, we present the first systematic study on isostructural 2D coordination polymers (CPs) based on 1,1′-ferrocenediyl-bis(H-phosphinic) acid, with cobalt, manganese, and cadmium metals as electrocatalysts for OER. These polymers were synthesized via a facile solution reaction, yielding crystalline materials with excellent structural integrity. The electrocatalytic performance of CPs composites, prepared with carbon and phosphonium ionic liquid, was evaluated in 0.1 M KOH using a three-electrode system. Notably, the Co- and Cd-based CPs demonstrated exceptional OER activity, achieving an overpotential as low as 236–255 mV at 10 mA cm⁻², surpassing those of many previously reported CP-based OER catalysts. Furthermore, these materials exhibited high stability over prolonged electrolysis, maintaining their activity without significant degradation. This work not only introduces a new class of ferrocenyl phosphinate-based CPs as highly active and durable OER catalysts but also provides valuable insights into their structure-activity relationships, paving the way for future advancements in electrocatalysis.

析氧反应（OER）是水裂解制氢的关键过程，但其缓慢的反应动力学给催化剂的开发带来了重大挑战。在这项工作中，我们首次系统地研究了基于1,1 ' -二茂铁-双（h -膦）酸的同结构二维配位聚合物（CPs），钴、锰和镉金属作为OER的电催化剂。这些聚合物是通过简单的溶液反应合成的，产生具有优异结构完整性的晶体材料。在0.1 M KOH条件下，采用三电极体系对碳磷离子液体制备的CPs复合材料的电催化性能进行了研究。值得注意的是，基于Co和cd的CPs表现出了出色的OER活性，在10 mA cm - 2下的过电位低至236-255 mV，超过了许多先前报道的基于cp的OER催化剂。此外，这些材料在长时间电解过程中表现出高稳定性，保持其活性而不显着降解。这项工作不仅介绍了一类新的磷酸二铁基CPs作为高活性和耐用的OER催化剂，而且还提供了对其结构-活性关系的有价值的见解，为电催化的未来发展铺平了道路。

Organic electrodes are considered competitive candidates for the next-generation high-performance energy storage devices owing to their advantages of structural flexibility and abundant resources. However, solubility and low electronic conductivity have been major obstacles to the practical application. To address these challenges, the structural design and interfacial regulation of organic electrodes are crucial to the performance enhancement. Herein, we report on a π-conjugated polymer cathode material of poly(3,4,9,10-perylenetetracarboxylic diimide) (PPI) for metal ion batteries, and the performance optimization is achieved by matching suitable conductive carbons and liquid electrolytes. Ultimately, the carbon nanotubes (CNTs) with weight content of 25% and 1 M NaPF₆ in ethylene carbonate/diethyl carbonate electrolyte are introduced to assemble the batteries, and the discharge specific capacity, cycling stability and rate performance are enhanced effectively. The PPI-CNT||Na battery displays high specific capacities of 146.4 and 117 mAh g⁻¹ at current densities of 0.1 C and 5 C, respectively. Furthermore, PPI-CNT||Na battery demonstrates excellent long-term cycling stability of 5000 cycles with low 0.007 mAh g⁻¹ capacity decay per cycle at 1C due to the thin and uniform cathode electrolyte interphase. Moreover, the PPI-CNT||Na battery presents good cycling stability at high temperatures of 60 °C, and retains a capacity of 132.5 mAh g⁻¹ after 300 cycles with a high capacity retention rate of 96.9%. Besides, PPI-CNT displays good electrochemical performance and compatibility in lithium-ion and potassium-ion batteries. This work provides an alternative optimization strategy for organic electrodes applied in long-lifetime metal ion batteries.

Aqueous zinc-metal based batteries (AZMBs) perfectly combine safety, economy and pro-environment, but their performance is arresting limited by the interfacial instability caused by the large desolvation energy barrier of [Zn(H₂O)₆]²⁺ and the massive release of active water at the electrolyte/electrode interface. In this review, we briefly outline the solvation structure of zinc ions and the necessity of desolvation. Subsequently, the variety of strategies to solve these issues, mainly including reorganizing solvation sheath by changing electrolyte environment and accelerating interface desolvation by constructing artificial interfacial layer, are categorically discussed and systematically summarized. Meanwhile, perspectives and suggestions regarding desolvation theories, interfacial evolution, material design and analysis techniques are proposed to design highly stable zinc anodes.

金属锌水溶液电池（azmb）完美地结合了安全性、经济性和环保性，但由于[Zn(H2O)6]2+的脱溶能势大和活性水在电解质/电极界面的大量释放而导致界面不稳定，限制了其性能。本文简要介绍了锌离子的溶剂化结构及溶剂化的必要性。随后，对解决这些问题的各种策略进行了分类和系统的总结，主要包括通过改变电解质环境来重组溶剂化鞘和通过构建人工界面层来加速界面脱溶。同时，从脱溶理论、界面演化、材料设计和分析技术等方面对高稳定性锌阳极的设计提出了展望和建议。

Solid polymer electrolytes (SPEs) have attracted much attention for their safety, ease of packaging, cost-effectiveness, excellent flexibility and stability. Poly-dioxolane (PDOL) is one of the most promising matrix materials of SPEs due to its remarkable compatibility with lithium metal anodes (LMAs) and suitability for in-situ polymerization. However, poor thermal stability, insufficient ionic conductivity and narrow electrochemical stability window (ESW) hinder its further application in lithium metal batteries (LMBs). To ameliorate these problems, we have successfully synthesized a polymerized-ionic-liquid (PIL) monomer named DIMTFSI by modifying DOL with imidazolium cation coupled with TFSI⁻ anion, which simultaneously inherits the lipophilicity of DOL, high ionic conductivity of imidazole, and excellent stability of PILs. Then the tridentate crosslinker trimethylolpropane tris[3-(2-methyl-1-aziridine)propionate] (TTMAP) was introduced to regulate the excessive Li⁺-O coordination and prepare a flame-retardant SPE (DT-SPE) with prominent thermal stability, wide ESW, high ionic conductivity and abundant Li⁺ transference numbers (t_Li₊). As a result, the LiFePO₄|DT-SPE|Li cell exhibits a high initial discharge specific capacity of 149.60 mAh g⁻¹ at 0.2C and 30 °C with a capacity retention rate of 98.68% after 500 cycles. This work provides new insights into the structural design of PIL-based electrolytes for long-cycling LMBs with high safety and stability.

固体聚合物电解质（spe）因其安全性、易于包装、成本效益、优异的灵活性和稳定性而受到广泛关注。聚二氧索烷（PDOL）具有与锂金属阳极（lma）良好的相容性和原位聚合性能，是极具发展前景的SPEs基体材料之一。但其热稳定性差、离子电导率不足、电化学稳定窗口（ESW）窄，阻碍了其在锂金属电池（lmb）中的进一步应用。为了改善这些问题，我们成功地用咪唑阳离子偶联TFSI -阴离子修饰DOL，合成了一种名为DIMTFSI的聚合离子液体（PIL）单体，同时继承了DOL的亲脂性、咪唑的高离子电导率和PIL优异的稳定性。然后引入三叉交联剂三甲基丙烷三[3-（2-甲基-1-叠氮吡啶）丙酸盐]（TTMAP）来调节过量的Li+- o配位，制备出热稳定性好、ESW宽、离子电导率高、Li+转移数（tLi+）丰富的阻燃剂SPE （DT-SPE）。结果表明，LiFePO4|DT-SPE|锂电池在0.2C和30°C条件下具有149.60 mAh g−1的高初始放电比容量，循环500次后容量保持率为98.68%。这项工作为长循环lmb的结构设计提供了新的见解，具有高安全性和稳定性。

In this work, we have applied molybdenum (Mo) and titanium (Ti) co-doping to solve the degradation of Ni-rich cathodes. The modified cathode, i.e., Li(Ni_0.89Co_0.05Mn_0.05Mo_0.005Ti_0.005)O₂ holds a stable structure with expanded crystal lattice distance which improves Li ion diffusion kinetics. The dopants have suppressed the growth of primary particles, formed a coating on the surface, and promoted the elongated morphology. Moreover, the mechanical strength of these particles has increased, as confirmed by the nanoindentation test, which can help suppress particle cracking. The detrimental H2-H3 phase transition has been postponed by 90 mV allowing the cathode to operate at a higher voltage. A better cycling stability over 100 cycles with 69% capacity retention has been observed. We believe this work points out a way to improve the cycling performance, Coulombic efficiency and capacity retention in Ni-rich cathodes.

在这项工作中，我们应用钼（Mo）和钛（Ti）共掺杂来解决富镍阴极的降解问题。改性后的阴极Li(Ni0.89Co0.05Mn0.05Mo0.005Ti0.005)O2结构稳定，晶格距离扩大，提高了Li离子的扩散动力学。掺杂剂抑制了初生颗粒的生长，在表面形成一层涂层，促进了晶粒的伸长形貌。此外，纳米压痕试验证实，这些颗粒的机械强度有所提高，有助于抑制颗粒的开裂。有害的H2-H3相变被推迟了90 mV，使得阴极可以在更高的电压下工作。在100次循环中，有更好的循环稳定性，容量保留率为69%。我们认为这项工作为提高富镍阴极的循环性能、库仑效率和容量保持率指明了一条途径。

Sodium-ion batteries (SIBs) are emerging as a promising alternative for large-scale energy storage, particularly in grid applications. Within the array of potential cathode materials, Fe/Mn-based layered oxides are notable for their advantageous theoretical specific capacity, economic viability, and environmental sustainability. Nevertheless, the practical application of Fe/Mn-based layered oxides is constrained by their suboptimal cycle performance and rate capability during actual charging and discharging. Ion doping is an effective approach for addressing the aforementioned issues. In this context, we have successfully developed a novel K⁺ and Mg²⁺ co-doped P2-Na_0.7Fe_0.5Mn_0.5O₂ cathode to address these challenges. By doping with 0.05 K⁺ and 0.2 Mg²⁺, the cathode demonstrated excellent cycling stability, retaining 95% of its capacity after 50 cycles at 0.2C, whereas the undoped material retained only 59.7%. Even within a wider voltage range, the co-doped cathode retained 88% of its capacity after 100 cycles at 1C. This work integrated Mg²⁺ to activate oxygen redox reactions in Fe/Mn-based layered cathodes, thereby promoting a reversible hybrid redox process involving both anions and cations. Building on the Mg doping, larger K⁺ ions were introduced into the edge-sharing Na⁺ sites, enhancing the material's cyclic stability and expanding the interplanar distance.

钠离子电池（sib）正在成为大规模能源存储的一种有前途的替代方案，特别是在电网应用中。在一系列潜在的正极材料中，铁/锰基层状氧化物以其优越的理论比容量、经济可行性和环境可持续性而闻名。然而，铁/锰基层状氧化物的实际应用受到其在实际充放电过程中的次优循环性能和倍率能力的限制。离子掺杂是解决上述问题的有效途径。在此背景下，我们成功开发了一种新的K+和Mg2+共掺杂的P2-Na0.7Fe0.5Mn0.5O2阴极来解决这些挑战。当掺杂0.05 K+和0.2 Mg2+时，阴极表现出了良好的循环稳定性，在0.2 c下循环50次后，阴极的容量保留了95%，而未掺杂的材料仅保留了59.7%。即使在更宽的电压范围内，共掺杂阴极在1C下循环100次后仍能保持88%的容量。本研究将Mg2+集成到Fe/ mn基层状阴极中，激活氧氧化还原反应，从而促进阴离子和阳离子的可逆混合氧化还原过程。在Mg掺杂的基础上，更大的K+离子被引入到共用边的Na+位点，增强了材料的循环稳定性，扩大了材料的面间距离。通过恒流间歇滴定技术（git）进一步证实了K+/Mg2+共掺杂对Na+扩散系数的显著改善。该研究强调了不同配位环境的共掺杂在未来材料设计中的重要性，旨在实现高工作电压和能量密度。

Nickel (Ni)-rich layered oxides have drawn great attention as cathode for lithium batteries due to their high capacity, high working voltage and competitive cost. Unfortunately, the operation of Ni-rich cathodes suffers from the notorious structural degradation and interfacial side reactions with electrolytes and thus incurs premature failure, especially at high charge cut-off voltages (≥4.4 V). For this, various structural and interphase regulation strategies (such as coating modification, element doping, and electrolyte engineering) are developed to enhance the cycling survivability of Ni-rich cathodes. Among them, electrolyte engineering by changing solvation structure and introducing additives has been considered an efficient method for constructing robust cathode-electrolyte interphases (CEI), inhibiting the formation of harmful species (such as HF and H₂O) or restraining the dissolution of transition metal ions. However, there is still an absence of systematic guidelines for selecting and designing competitive electrolyte systems for Ni-rich layered cathodes. In this review, we comprehensively summarize the recent research progress on electrolyte engineering for Ni-rich layered cathodes according to their working mechanisms. Moreover, we propose future perspectives of improving the electrolyte performance, which will provide new insights for designing novel electrolytes toward high-performance Ni-rich layered cathodes.

富镍层状氧化物因其高容量、高工作电压和具有竞争力的成本而成为锂电池正极材料。然而，富镍阴极的结构退化和与电解质的界面副反应导致其过早失效，特别是在高电荷截止电压（≥4.4 V）下。为此，研究人员开发了各种结构和界面调节策略（如涂层改性、元素掺杂和电解质工程）来提高富镍阴极的循环生存性。其中，通过改变溶剂化结构和引入添加剂的电解质工程被认为是构建坚固的阴极-电解质界面（CEI）、抑制有害物质（如HF和H2O）的形成或抑制过渡金属离子溶解的有效方法。然而，对于富镍层状阴极的竞争性电解质体系的选择和设计，仍然缺乏系统的指导方针。本文从富镍层状阴极的工作机理出发，综述了近年来富镍层状阴极电解液工程的研究进展。此外，我们提出了改善电解质性能的未来前景，这将为设计高性能富镍层状阴极的新型电解质提供新的见解。

The repeated volume variation of lithium (Li) metal anode (LMA) upon Li⁺ plating/stripping, the volatile interface between Li and the electrolyte, and the incessant growth of Li dendrites on Li metal surface have severely hindered the practical application of Li in constructing high energy-density Li metal batteries (LMBs). Herein, a novel Li host (3D ZnO/CNTs/Cu) featuring ordered microchannels and lithiophilic ZnO species on the inner walls of the microchannels is introduced, which induces the uniform Li⁺ deposition into the microchannels and finally suppresses the formation of Li dendrites. The stable structure of the fabricated 3D Li host can adapt to volume variations upon Li⁺ plating/stripping, thereby enhancing electrochemical performances. Symmetric cells with the 3D ZnO/CNTs/Cu@Li anode exhibited long cycle stability at areal current densities of 0.5 and 2 mA cm⁻²; Full cells maintained a reversible discharge capacity of 105 mAh g⁻¹ after 400 cycles at 1C with a capacity retention of 70%. Meanwhile, ex-situ SEM observations proved that the 3D ZnO/CNTs/Cu@Li anode can keep the structural integrity during charging/discharging (or plating/stripping). This work suggested that lithiophilic nanochannels in the Li host can significantly improve the electrochemical performance and safety of LMBs.

锂金属阳极（LMA）在镀/剥离锂离子过程中体积的反复变化、锂与电解液界面的易挥发性以及锂金属表面枝晶的不断生长严重阻碍了锂在构建高能量密度锂金属电池（lmb）中的实际应用。本文引入了一种新型的Li寄主（3D ZnO/CNTs/Cu），具有有序的微通道和微通道内壁上的亲锂性ZnO，诱导Li+均匀沉积到微通道中，最终抑制Li枝晶的形成。制备的3D锂基质结构稳定，可以适应锂离子电镀/剥离时的体积变化，从而提高电化学性能。采用三维ZnO/CNTs/Cu@Li阳极的对称电池在0.5和2 mA cm−2的面电流密度下表现出长周期稳定性；在1C下循环400次后，充满电池的可逆放电容量保持在105 mAh g−1，容量保持率为70%。同时，非原位SEM观察证明，三维ZnO/CNTs/Cu@Li阳极在充放电（或镀/剥离）过程中可以保持结构的完整性。本研究表明，在Li基质中添加亲锂纳米通道可以显著提高lmb的电化学性能和安全性。
