Na superionic conductor (NASICON)-type cathode materials have attracted considerable attention owing to their robust framework and excellent sodium-ion conductivity. However, these materials still suffer from intrinsic issues such as voltage hysteresis, capacity fading, and Jahn-Teller distortions, which critically hinder their practical applicability. Herein, a rare earth element Ce-doped Na₃Mn_0.95Ce_0.05Ti(PO₄)₃ (NMCTP) cathode material with reduced intrinsic anti-site defects is designed through local electronic modulation, resulting in suppressed voltage hysteresis and enhanced sodium-ion diffusion. Ce doping, through its highly localized 4f electronic structure, leads to a contraction of the neighboring Mn-O bonds even when the Mn valence state decreases. The strong ionic character of Ce and the suppression of Mn Jahn-Teller distortion collaboratively induce local bonding reconstruction, thereby strengthening the stability of the MnO₆ octahedra. Enabled by the Ce-induced electronic structure modulation, NMCTP delivers a high specific capacity of 171.4 mA h g⁻¹ at 0.1C and enhanced cycling stability, with capacity retention improved from ∼50.3 % to ∼73.8 % after 500 cycles at 2 C. This work provides an efficient strategy for suppressing voltage hysteresis and Jahn-Teller distortion through local lattice optimization and electronic structure modulation, advancing the practical application of NASICON-type materials in next-generation energy storage systems.

钠离子超导体（NASICON）型正极材料因其坚固的结构和优异的钠离子导电性而受到广泛关注。然而，这些材料仍然存在固有的问题，如电压滞后、容量衰落和Jahn-Teller畸变，这些问题严重阻碍了它们的实际应用。本文通过局部电子调制，设计了一种稀土元素ce掺杂Na3Mn0.95Ce0.05Ti(PO4)3 （NMCTP）正极材料，减少了本征反位缺陷，从而抑制了电压滞后，增强了钠离子扩散。Ce掺杂通过其高度局域化的4f电子结构，导致相邻的Mn- o键收缩，即使Mn价态降低。Ce的强离子特性和Mn的jhn - teller畸变抑制共同诱导了局部键重建，从而增强了MnO6八面体的稳定性。通过ce诱导的电子结构调制，NMCTP在0.1C时提供了171.4 mA h g−1的高比容量，并增强了循环稳定性，在2 c下循环500次后，容量保持率从~ 50.3%提高到~ 73.8%。这项工作提供了一种有效的策略，通过局部晶格优化和电子结构调制来抑制电压滞后和Jahn-Teller扭曲。推进nasicon型材料在下一代储能系统中的实际应用。

Rechargeable aqueous zinc-manganese batteries (AZMBs) have received widespread attention as next-generation large-scale energy storage devices. However, there is still some controversy regarding the energy storage mechanism of the cathode materials. The deposition of manganese ions on the cathode is facilitated by the byproduct zinc hydroxide sulfate (ZHS), and both this process and the ion intercalation mechanism contribute substantially to the capacity. Herein, by constructing an alkaline and manganese-free substrate to decouple mechanisms, the capacity fading issues and resolution strategies based on the ZHS-assisted manganese deposition mechanism are comprehensively investigated. An "acid-in-alkali" substrate (AlO-ZnO) was designed with the fundamental principles of using the alkali (ZnO) to assist in manganese deposition and the acid (AlO) to aid in manganese dissolution. Specifically, Brønsted acidic sites (AlO) within the alkaline substrate structure capitalize on the proton self-limiting effect to generate a localized acidic environment at the cathode, in order to inhibit and activate dead Mn for enhanced energy density and cycle life. As a result, long-term cycle stability (2000 cycles with 98% retention) and high-rate performance are achieved. This work provides a new perspective for significantly improving the cycle stability of AZMBs and upgrading the mechanism cognition.

可充水锌锰电池（azmb）作为下一代大规模储能设备受到了广泛关注。然而，关于正极材料的储能机理还存在一些争议。副产物硫酸氢氧化锌（ZHS）促进了锰离子在阴极上的沉积，这一过程和离子嵌入机制都对容量有重要贡献。本文通过构建碱性和无锰衬底来解耦机制，全面研究了基于zs辅助锰沉积机制的容量衰落问题和解决策略。基于碱（ZnO）助锰沉积和酸（AlO）助锰溶解的基本原理，设计了一种“酸中碱”底物（AlO-ZnO）。具体来说，碱性底物结构中的Brønsted酸性位点（AlO）利用质子自限效应在阴极产生局部酸性环境，以抑制和激活死锰，提高能量密度和循环寿命。因此，实现了长期循环稳定性（2000次循环，保留率98%）和高速率性能。本研究为显著提高azmb的循环稳定性和提升机理认知提供了新的视角。

Lithium metal batteries (LMBs) have shown significant interest as next-generation energy storage systems due to their ultra-high theoretical specific capacity of 3,860 mAh g⁻¹. However, dendrite growth remains a major obstacle to commercialization, driven by instabilities in the native passivation layer (NPL) and the solid electrolyte interphase (SEI). The NPL, formed by lithium’s reactivity with ambient gases, induces uneven current distributions, while fragile SEIs crack easily, exposing fresh lithium and triggering parasitic reactions.

This review combines experimental and computational approaches to understand and improve these interfacial layers. For the NPL, mechanothermal milling, picosecond laser treatments, vacuum thermal evaporation, and engineered electrodeposition layers have been employed to smooth surfaces and lower resistance. For the SEI, approaches such as artificial SEIs, electrolyte additives, solid-state electrolytes (SSEs), anode modification, and separator engineering enhance stability and suppress dendrite growth. Complementarily, computational methods including density functional theory (DFT), molecular dynamics (MD), ab initio molecular dynamics (AIMD), kinetic Monte Carlo (KMC), and machine learning (ML) provide atomistic insights into interfacial reactions and ion transport.

Together, these experimental and computational approaches provide a unified framework that guides the design of stable interfacial layers and accelerates the safe commercialization of high-energy LMBs.

锂金属电池（lmb）由于具有3860 mAh g−1的超高理论比容量，已成为下一代储能系统的重要组成部分。然而，由于原生钝化层（NPL）和固体电解质间相（SEI）的不稳定性，枝晶生长仍然是商业化的主要障碍。NPL由锂与环境气体的反应性形成，导致电流分布不均匀，而脆弱的sei容易破裂，暴露新鲜的锂并引发寄生反应。本文将结合实验和计算方法来理解和改进这些界面层。对于NPL，机械热铣削、皮秒激光处理、真空热蒸发和工程电沉积层已被用于光滑表面和降低电阻。对于SEI，人工SEI、电解质添加剂、固态电解质（ssi）、阳极改性和分离器工程等方法可以提高稳定性并抑制枝晶生长。此外，包括密度泛函理论（DFT）、分子动力学（MD）、从头算分子动力学（AIMD）、动力学蒙特卡罗（KMC）和机器学习（ML）在内的计算方法提供了对界面反应和离子传输的原子性见解。总之，这些实验和计算方法提供了一个统一的框架，指导稳定界面层的设计，加速高能lmb的安全商业化。

Anode-free sodium metal batteries (AFSMBs) hold great promise for high-energy sodium storage but are plagued by unstable interfaces and dendritic sodium growth arising from uneven plating and stripping. Here, we introduce a magnetic–electric dual-field interfacial regulation strategy by engineering a FeCoNiCuSn multicomponent alloy (MA) integrated with a carbon nanotube (CNT) scaffold on commercial aluminum foil (MA@CNT). The interconnected CNT framework provides a three-dimensional conductive network that accommodates volume changes and firmly anchors MA nanoparticles. The Sn component ensures homogeneous Na nucleation, while Cu, Fe, Co, and Ni form multicomponent alloys with Sn to mitigate volume expansion during cycling. More importantly, the magnetic elements (Fe, Co, Ni) create localized magnetic fields that direct Na⁺ flux through Lorentz-force-driven migration, leading to uniform deposition and effective suppression of dendritic growth–an interfacial regulation mechanism unexplored in AFSMBs. Benefiting from these synergistic effects, MA@CNT||Na asymmetric cells deliver stable cycling for over 600 cycles at 1 mA cm^–², and the MA@CNT||Na₃V₂(PO₄)₃ full cells exhibit excellent rate capability and long-term stability. This study establishes magnetic-interface engineering as a powerful strategy to achieve dendrite-free sodium deposition, offering a new paradigm for the design of stable, high-performance anode-free sodium metal batteries.

无阳极金属钠电池（AFSMBs）在高能钠存储方面具有很大的前景，但由于镀层和剥离不均匀而导致界面不稳定和枝状钠生长而受到困扰。本文介绍了一种磁电双场界面调节策略，通过将FeCoNiCuSn多组分合金（MA）与碳纳米管（CNT）支架集成在商用铝箔上（MA@CNT）。相互连接的碳纳米管框架提供了一个三维导电网络，可以适应体积变化并牢固地锚定MA纳米颗粒。Sn成分确保了均匀的Na形核，而Cu、Fe、Co和Ni与Sn形成多组分合金，以减轻循环过程中的体积膨胀。更重要的是，磁性元素（Fe, Co, Ni）产生了局部磁场，引导Na⁺的通量通过洛伦兹力驱动的迁移，导致均匀沉积并有效抑制枝晶生长——这是afsmb中尚未探索的界面调节机制。受益于这些协同效应，MA@CNT||Na不对称电池在1 mA cm-2下提供超过600次的稳定循环，MA@CNT||Na₃V₂（PO₄）₃全电池表现出优异的速率能力和长期稳定性。本研究确立了磁界面工程作为实现无枝晶钠沉积的有力策略，为设计稳定、高性能的无阳极金属钠电池提供了新的范例。

Most alloying-type anodes for Na-ion batteries are fundamentally limited in ultrafast-charging applications due to the formation of Zintl phases: intermetallic compounds with intrinsically high electrical resistivity. This work demonstrates how to overcome this fundamental limitation by employing metal sulfide-based conversion anodes (NiS, CuS, and MnS), which follow a distinct electrochemical pathway that avoids Zintl-phase formation. During cycling in ether-based electrolytes, these sulfides undergo conversion reactions that spontaneously generate highly conductive, in-situ formed metal nanoparticles embedded within a self-assembled three-dimensional nanoporous Na₂S matrix. This unique composite structure forms a dual-function architecture that enables both efficient ion diffusion and long-range electron transport, even when using inexpensive microsized sulfide particles. Among the tested materials, NiS exhibits the best performance, delivering a reversible capacity of 600 mAh g^–1 at 1C, exceptional cycling stability over 3800 cycles at 10C, and a high-rate capacity of 358 mAh g^–1 at 30C. Density functional theory and machine-learning-based molecular dynamics simulations reveal that the strong Ni–S bonding in the intermediate phases suppresses nanoparticle coarsening, resulting in uniformly distributed, nanoscale Ni particles that form an efficient percolation network. These findings establish a new design paradigm for Zintl-free conversion anodes, offering a practical and scalable route toward high-performance, fast-charging Na-ion batteries.

大多数用于钠离子电池的合金型阳极从根本上限制了超快充电应用，因为形成了Zintl相：具有固有高电阻率的金属间化合物。这项工作展示了如何通过使用金属硫化物基转换阳极（NiS， cu和MnS）来克服这一基本限制，这些阳极遵循独特的电化学途径，避免了锌相的形成。在醚基电解质中循环时，这些硫化物发生转化反应，自发地产生高导电性的原位形成的金属纳米颗粒，嵌入在自组装的三维纳米多孔Na2S基质中。这种独特的复合结构形成了一种双重功能结构，即使在使用廉价的微型硫化物颗粒时，也能实现有效的离子扩散和远程电子传输。在所测试的材料中，NiS表现出最好的性能，在1C下可提供600 mAh g-1的可逆容量，在10℃下可提供超过3800次循环的卓越循环稳定性，在30℃下可提供358 mAh g-1的高速率容量。密度泛函理论和基于机器学习的分子动力学模拟表明，中间相的强Ni - s键抑制了纳米颗粒的粗化，导致均匀分布的纳米级Ni颗粒形成有效的渗透网络。这些发现为无锌转换阳极建立了一个新的设计范例，为高性能、快速充电的钠离子电池提供了一条实用且可扩展的途径。

Triggering the anionic redox reaction (ARR) of manganese rich cathode materials has become a prevalent strategy for developing low-cost and high-energy sodium-ion batteries. However, the practical implementation of ARR is substantially hindered by irreversible oxygen loss, structural degradation, and continuous voltage decay, which are often associated with weak Mn–O hybridization. Strengthening the Mn–O interaction is therefore crucial to activate and stabilize the lattice oxygen and achieve reversible redox chemistry. To tackle this issue, we design a superlattice cathode with the composition of (Na_0.69Li_0.01)Mn_0.5Ni_0.18Fe_0.06Li_0.06Cu_0.05Ti_0.15O₂ through a high-entropy strategy to optimize the Mn–O orbital interaction. The tailored multi-cation configuration enhances Mn–O hybridization, suppressing cation migration and oxygen release. The inherent superlattice structure further stabilizes the structure through orbital hybridization, as confirmed by spectroscopic and structural analyses. As a result, the cathode delivers a high specific capacity of 164.4 mAh g^-1 with an average voltage of 3.54 V, achieving a high practical energy density of 210.4 Wh kg^-1 in full cells, and demonstrates exceptional long-term cycling stability. This work highlights the critical role of high entropy-mediated Mn–O hybridization enabling reversible anionic redox chemistry, presenting a transformative design strategy for high-energy and long-life sodium-ion batteries.

触发富锰正极材料的阴离子氧化还原反应（ARR）已成为开发低成本高能量钠离子电池的普遍策略。然而，ARR的实际实施受到不可逆氧损失、结构降解和连续电压衰减的极大阻碍，这些通常与弱Mn-O杂化有关。因此，加强Mn-O相互作用对于激活和稳定晶格氧和实现可逆氧化还原化学至关重要。为了解决这一问题，我们设计了一种由（Na0.69Li0.01）Mn0.5Ni0.18Fe0.06Li0.06Cu0.05Ti0.15O2组成的超晶格阴极，通过高熵策略优化Mn-O轨道相互作用。量身定制的多阳离子结构增强了Mn-O杂化，抑制了阳离子迁移和氧释放。光谱和结构分析证实，固有的超晶格结构通过轨道杂化进一步稳定了结构。因此，阴极提供了164.4 mAh g-1的高比容量，平均电压为3.54 V，在充满电池的情况下实现了210.4 Wh kg-1的高实用能量密度，并表现出出色的长期循环稳定性。这项工作强调了高熵介导的Mn-O杂化在可逆阴离子氧化还原化学中的关键作用，提出了一种高能长寿命钠离子电池的变革性设计策略。

During the initial charging process, lithium-ion batteries suffer from active lithium loss, which leads to a reduction in both the initial Coulombic efficiency and reversible capacity. Prelithiation emerges as an effective strategy to address this issue and enhance the energy density of these batteries. Nevertheless, conventional prelithiation agents, particularly lithium metal foil and highly reactive lithium compounds, are often limited by poor environmental stability and potential safety concerns, which significantly impede their practical application. This work reports the development and investigation of novel cathode prelithiation materials, Li₆Zn_0.8M_0.2O₄ (M = Fe, Ni, Co and Mn). The delithiation capacity of Li₆ZnO₄ was successfully activated by the introduction of Co and Mn ions. Notably, Li₆Zn_0.8Co_0.2O₄ delivers an initial charging capacity of 722.7 mAh g^–1 and a lithium-supplement capacity of 714.2 mAh g^–1, while Li₆Zn_0.8Mn_0.2O₄ achieves 725.2 and 717.9 mAh g^–1, respectively, demonstrating excellent electrochemical performance and application potential. Further systematic evaluation within coin full-cell configurations, utilizing both Si/C and graphite anodes, confirms that the incorporation of Li₆Zn_0.8Co_0.2O₄ and Li₆Zn_0.8Mn_0.2O₄ leads to a marked improvement in both initial discharge capacity and capacity retention. This study not only provides a new direction for designing and optimizing prelithiation agents but also offers valuable insights for developing high-performance lithium-ion batteries.

在初始充电过程中，锂离子电池会发生活性锂损失，导致初始库仑效率和可逆容量下降。预锂化技术是解决这一问题和提高电池能量密度的有效策略。然而，传统的预锂化剂，特别是锂金属箔和高活性锂化合物，往往受到环境稳定性差和潜在安全问题的限制，这极大地阻碍了它们的实际应用。本文报道了新型阴极预锂化材料Li6Zn0.8M0.2O4 （M = Fe, Ni， Co和Mn）的开发和研究。通过引入Co和Mn离子，成功激活了Li6ZnO4的降解能力。值得注意的是，li6zn0.8 mn0.2 2o4的初始充电容量为722.7 mAh g-1，锂补充容量为714.2 mAh g-1, li6zn0.8 mn0.2 2o4的初始充电容量分别为725.2 mAh g-1和717.9 mAh g-1，表现出优异的电化学性能和应用潜力。采用Si/C和石墨阳极的硬币式全电池结构进一步进行系统评估，证实了Li6Zn0.8Co0.2O4和Li6Zn0.8Mn0.2O4的加入在初始放电容量和容量保持方面都有显著改善。该研究不仅为预锂化剂的设计和优化提供了新的方向，而且为高性能锂离子电池的开发提供了有价值的见解。

Tin-based chalcogenides hold great promise as high-energy anodes for sodium-ion batteries (SIBs) due to their rich redox chemistry, yet their performance is hindered by sluggish ion transport and structural degradation. Herein, we present sophisticated multinary SnSSeTe/C core-shell nanostructures, wherein the concurrent incorporation of Se and Te not only establishes robust interfacial C-Se-Te-Sn bonds but also induces precise lattice-level substitution within SnS, thereby unlocking unprecedented structural and electronic tunability, along with structural resilience, significantly facilitating the reverse alloy conversion mechanism. Comprehensive kinetic analyses and in situ characterization reveal that anion substitution generates abundant lattice vacancies, which not only enhance Na-ion adsorption but also open fast-diffusion channels for accelerated transport kinetics. Density functional theory calculations further confirm that selenium/tellurium-rich coordination weakens polar C-S-Sn bonding and lowers redox energy barriers, thus markedly accelerating reaction dynamics. Consequently, the SnSSeTe/C anode delivers ultrahigh initial Coulombic efficiency of 91.71%, excellent rate capability, and long-term cycling stability with a reversible capacity of 395 mAh g^-1 over 2000 cycles at a high current density of 5 A g^-1. Moreover, a full SIB assembled with a Na₃V₂(PO₄)₃/C cathode achieves an impressive energy density of 258 Whkg^-1. This work underscores the disruptive potential of multinary structural engineering in guiding rational electrode design toward high-performance SIBs for sustainable energy.

锡基硫族化合物由于其丰富的氧化还原化学性质，作为钠离子电池（sib）的高能阳极具有很大的前景，但其性能受到离子传输缓慢和结构降解的阻碍。在此，我们提出了复杂的多SnSSeTe/C核壳纳米结构，其中Se和Te的同时结合不仅建立了坚固的界面C-Se-Te- sn键，而且还在SnS内部诱导了精确的晶格级取代，从而解锁了前所未有的结构和电子可调性，以及结构弹性，显著促进了合金的反向转化机制。综合动力学分析和原位表征表明，阴离子取代产生了丰富的晶格空位，这不仅增强了钠离子的吸附，而且为加速运输动力学打开了快速扩散通道。密度泛函理论计算进一步证实，富硒/富碲配位弱化极性C-S-Sn键，降低氧化还原能垒，从而显著加快反应动力学。因此，SnSSeTe/C阳极具有高达91.71%的超高初始库仑效率，出色的倍率能力和长期循环稳定性，在5 a g-1的高电流密度下，在2000次循环中可逆容量为395 mAh g-1。此外，用Na3V₂（PO₄）₃/C阴极组装的完整SIB达到了258 Whkg-1的能量密度。这项工作强调了多结构工程在指导合理电极设计以实现可持续能源高性能sib方面的颠覆性潜力。

Anode-free full cells are considered an emerging architecture in battery technology, capable of achieving maximum energy densities, low manufacturing costs, and minimum environmental footprints for aqueous Zn metal batteries (AZMBs). However, limited Zn sources and unavoidable irreversible interfacial reactions hinder the practical applications of anode-free ZMBs (AFZMBs). Herein, we comprehensively review recent progress on the materials and corresponding interfacial engineering for energy-dense and long cyclable AFZMBs. The fundamental understanding of the working principle, features, and major challenges of AFZMBs is addressed. Furthermore, various strategies for improving the performance of AFZMBs are discussed symmetrically from the aspects of electrolyte and interfacial engineering. Finally, we offer our perspectives on the future development of AFZMBs, aiming to develop energy-dense and cost-effective full batteries for emerging and practical applications.

Layered oxide has been regarded as one of the most promising cathode materials for sodium-ion batteries (SIBs) owing to its high theoretical energy density. However, irreversible phase transitions at high voltages, lattice oxygen redox (O²⁻/O₂ⁿ⁻, 1 ≤ n ≤ 3), and sluggish Na⁺ kinetics still hinder its practical application intrinsically. Herein, we manipulate the intra- and interlayer structure of layered oxide cathodes by hierarchically employing a modified gallic acid (GA) polyphenol-metal complex with multi-elements co-regulated (Ca, Li, and Cu). Benefitted from self-assembly of GA, the as-prepared GA-Na_0.61Ni_0.23Mn_0.67Ca_0.05Li_0.05Cu_0.05O₂ (GA-NNM-CaLiCu) cathode reveals reduced oxygen vacancies (OVs) and enhanced crystallinity. The anchoring of interlayered Ca²⁺ generates a reinforced “pillar” effect and the strategically migration of Li⁺ into the transition-metal (TM) layer mitigates electrostatic repulsion. The redox active Cu²⁺ strengthens the interlayered Ni/Mn-O bonds, facilitating negligible structural strain under an extended voltage window (2-4.3 V). As a result, the GA-NNM-CaLiCu cathode delivers 144.8 mAh g^-1 at 0.1 C and retains 85.2% of its capacity after 1000 cycles at 20 C. This work provides a comprehensive approach to improve structural stability and reaction kinetics of P2-type Na_0.67Ni_0.33Mn_0.67O₂ (NNM) cathodes in SIBs.

层状氧化物由于具有较高的理论能量密度而被认为是最有前途的钠离子电池正极材料之一。然而，高压下的不可逆相变、晶格氧氧化还原（O2−/O2n−,1≤n≤3）、Na+动力学缓慢等问题仍然从本质上阻碍了其实际应用。在这里，我们通过分层使用修饰的没食子酸（GA）多酚金属配合物与多元素共调节（Ca， Li和Cu）来操纵层状氧化物阴极的层内和层间结构。得益于GA的自组装，GA- na0.61 ni0.23 mn0.67 ca0.05 li0.05 cu0.05 o2 （GA- nm - calicu）阴极的氧空位（OVs）减少，结晶度提高。层间Ca2+的锚定产生了增强的“支柱”效应，Li+向过渡金属（TM）层的战略性迁移减轻了静电排斥。氧化还原活性Cu2+增强了层间Ni/Mn-O键，在延长的电压窗口（2-4.3 V）下，可以忽略结构应变。结果表明，GA-NNM-CaLiCu阴极在0.1℃下可提供144.8 mAh g-1，在20℃下循环1000次后仍能保持85.2%的容量。这项工作为提高sib中p2型Na0.67Ni0.33Mn0.67O2 （NNM）阴极的结构稳定性和反应动力学提供了一种全面的方法。
