Sodium-ion capacitors (SICs), emerging as new energy storage devices with economic and strategic significance, encounter the obstacle of developing anode materials that are high-performance, economical, and environmentally sustainable. However, the advancement of hard carbon as a cost-effective anode material has been impeded due to its inadequate rate performance and cycling stability. Here, discarded mulberry branches are utilized as precursors. Through hydrothermal treatment, the interplanar spacing of graphite-like nanocrystals is expanded, leading to the construction of a hierarchical pore structure and optimization of the ion transmission route. Consequently, the hard carbon electrode achieves a high capacity of 330mAh g⁻¹ at 0.1 A g⁻¹, and maintains a substantial capacity of 175.5mAh g⁻¹ even under a high current density of 10 A g⁻¹. Notably, in extremely cold conditions of –50 °C, the electrode retains a capacity of 155mAh g⁻¹ at 0.1 A g⁻¹, with no significant capacity loss observed after 400 cycles at −20 °C and a current density of 1 A g⁻¹. This study introduces a straightforward and sustainable approach to fabricate advanced hard carbon derived from biomass for application in energy storage systems.

钠离子电容器（SIC）作为新兴的储能设备，具有重要的经济和战略意义，但在开发高性能、经济性和环境可持续性的阳极材料方面却遇到了障碍。然而，由于硬碳的速率性能和循环稳定性不足，阻碍了硬碳作为一种具有成本效益的阳极材料的发展。在这里，废弃的桑枝被用作前驱体。通过水热处理，扩大了类石墨纳米晶体的平面间距，从而构建了分层孔隙结构，优化了离子传输路径。因此，硬碳电极在 0.1 A g-1 的条件下实现了 330mAh g-1 的高容量，即使在 10 A g-1 的高电流密度下也能保持 175.5mAh g-1 的高容量。值得注意的是，在零下 50 摄氏度的极冷条件下，该电极在 0.1 A g-1 电流下仍能保持 155mAh g-1 的容量，在零下 20 摄氏度和 1 A g-1 电流密度下循环 400 次后也未观察到明显的容量损失。本研究介绍了一种直接、可持续的方法，用于制造先进的生物质硬碳，并将其应用于储能系统。

Structure regulation and doping modification are important means to enhance the electrochemical and electrochromic performance of anode NiO electrochromic films. How to improve cycle stability is crucial for the application of NiO electrochromic films. In this work, we prepared Ti-doped seed layers with varying precise chemical stoichiometry ratios through the sol–gel spin coating method. Subsequently, NiO composite films were successfully fabricated on these seed layers through a simple hydrothermal process. Notably, among all the samples, the A 1/8 sample exhibits superior electrochromic performance, including a large optical modulation amplitude (69.61 % at 550 nm), faster response time (5.0 and 6.2 s), high coloring efficiency (33.87 cm²/C), and excellent cycle stability (3300 cycles). The seed layer plays a crucial role in preventing direct contact between the electrolyte and the electrode, inducing the growth of self-assembled structures, and enhancing adhesion between the film and the electrode. The Ti-doped seed layer can regulate the composite film microstructure and band structure, impacting the film electrochromic properties. In this work, we demonstrate that the cycle stability of the NiO composite films is improved through dual regulation of structure and doping. The A 1/8 sample exhibits superior cycle stability, attributed to the coupling effect of multi-channel nanostructure, and reduces interface barrier with FTO.

结构调整和掺杂改性是提高阳极氧化镍电致变色薄膜电化学和电致变色性能的重要手段。如何提高循环稳定性对于氧化镍电致变色薄膜的应用至关重要。在这项工作中，我们通过溶胶-凝胶旋涂法制备了具有不同精确化学计量比的掺钛种子层。随后，通过简单的水热工艺，在这些种子层上成功制备了氧化镍复合薄膜。值得注意的是，在所有样品中，A 1/8 样品具有优异的电致变色性能，包括较大的光学调制幅度（550 纳米波长下为 69.61%）、较快的响应时间（5.0 和 6.2 秒）、较高的着色效率（33.87 cm2/C）和出色的循环稳定性（3300 次循环）。种子层在防止电解质与电极直接接触、诱导自组装结构的生长以及增强薄膜与电极之间的附着力方面起着至关重要的作用。掺钛种子层可以调节复合薄膜的微观结构和带状结构，从而影响薄膜的电致变色特性。在这项工作中，我们证明了通过结构和掺杂的双重调节，氧化镍复合薄膜的循环稳定性得到了改善。A 1/8 样品表现出优异的循环稳定性，这归功于多通道纳米结构的耦合效应，并降低了与 FTO 的界面势垒。

The high packing density of electrode materials is crucial for the miniaturization and lightweighting of energy storage devices. Nevertheless, a structural contradiction among high packing densities, sufficient ion, and electron transport channels is a challenge. In this research, a unique hydrangea-like compose (MnO₂@S-PCS-5) is synthetized by a convenient and environmentally friendly method. The composite comprises a spherical carbon material matrix and MnO₂ nanosheets, resulting in a high packing density of 1.79 g cm⁻³. Furthermore, the hydrangea-like structure exhibits a high number of active sites, facilitating ion transport and exhibiting excellent specific capacitance (Cv: 328.7 F cm⁻³). The asymmetric supercapacitors (MnO₂@S-PCS-5//YP-50) exhibit a maximum energy density of 38.4 Wh kg⁻¹ at a power density of 500 W kg⁻¹, with a wide voltage window of 2.0 V. The results demonstrate densification is important for miniaturization of energy storage devices.

Using film-forming additive is an important approach to address the incompatibility between high-reactive electrodes and electrolytes. However, the design and screening of these film-forming additives still rely on a trial-and-error method, which is inefficient and costly. Herein, we established a method for screening additives based on theoretical calculations, and supplemented by short-term experiments. Four sulfur-containing additives, 1,3,2-dioxathiane 2-oxide (PRS), 1,3-propanediolcyclic sulfate (PCS), 1,5,2,4-dioxadithiane 2,2,4,4-tetraoxide (MMDS), sulfolane (Sul), were selected for investigation. The theoretical calculation results indicated that the additive with a greater negative adsorption energy on the cathode than the solvent facilitate film formation on the cathode. This principle can also be applied to screen the anode film-forming additive. However, the calculated results can only provide the insight into the additives’ capacity to participate in film formation, without revealing the stability of the resulting interfacial film or the improvement in the battery’s electrochemical performance. To address this limitation, three efficient short-term experimental methods were designed to characterize the stability of interfacial film: electrochemical impedance spectroscopy, high-temperature (45 °C) storage, and chronoamperometry. The proposed method, combing experiments and theoretical calculation, improves the accuracy for screening of film-forming additives.

使用成膜添加剂是解决高活性电极与电解质不兼容问题的重要方法。然而，这些成膜添加剂的设计和筛选仍然依赖于试错法，效率低且成本高。在此，我们建立了一种以理论计算为基础、短期实验为补充的添加剂筛选方法。我们选择了四种含硫添加剂：1,3,2-二氧二噻烷 2-氧化物（PRS）、1,3-丙二醇环硫酸盐（PCS）、1,5,2,4-二氧二噻烷 2,2,4,4-四氧化物（MMDS）和砜烷（Sul）进行研究。理论计算结果表明，添加剂在阴极上的负吸附能大于溶剂，有利于阴极成膜。这一原理也可用于筛选阳极成膜添加剂。然而，计算结果只能说明添加剂参与成膜的能力，并不能揭示所形成的界面膜的稳定性或对电池电化学性能的改善。为了解决这一局限性，我们设计了三种高效的短期实验方法来表征界面薄膜的稳定性：电化学阻抗光谱法、高温（45 °C）储存法和时变测量法。所提出的方法结合了实验和理论计算，提高了筛选成膜添加剂的准确性。

Designing high-efficiency electrocatalysts for water oxidation has become increasingly important in the catalysis field owing to its implications for renewable energy production and storage. The production of hydrogen (H₂) from water is hampered by the very sluggish kinetics of the water-splitting process. Enhancement of effective oxygen evolution reaction (OER) electrocatalysts is also required to understand the primary barrier to OER. This article investigates the electrochemical activity of magnesium-doped bismuth copper titanate (Mg-BCTO) as an efficient catalyst for the OER in water electrolysis, a critical step in hydrogen production for sustainable energy. The synthesized materials, including various stoichiometries of Mg-doped BCTO, undergo thorough physical and electrochemical characterization using XRD, FT-IR, Raman, SEM, TEM, XPS, CV, EIS, and Tafel polarization analyses. Remarkably, Mg0.1 doped BCTO demonstrates superior performance, achieving a current density of 10 mA cm⁻² at a very low overpotential (η₁₀) of 265 mV and with a Tafel slope of 92 mV dec⁻¹. This finding not only highlights the electrocatalytic efficiency of Mg doped BCTO but also positions it as a promising model for the development of highly active and stable water oxidizing catalysts, contributing to the advancement of clean energy technologies.

由于水氧化对可再生能源的生产和储存具有重要意义，因此设计高效的水氧化电催化剂在催化领域变得越来越重要。从水中制取氢气（H2）的过程因水分裂过程的动力学非常缓慢而受到阻碍。要了解氧进化反应的主要障碍，还需要增强有效的氧进化反应（OER）电催化剂。本文研究了掺镁钛酸铋铜（Mg-BCTO）作为水电解 OER 的高效催化剂的电化学活性，水电解是可持续能源制氢的关键步骤。利用 XRD、FT-IR、拉曼、扫描电镜、TEM、XPS、CV、EIS 和 Tafel 极化分析，对合成材料（包括不同化学计量的掺镁 BCTO）进行了全面的物理和电化学表征。令人瞩目的是，掺杂了 Mg0.1 的 BCTO 表现出卓越的性能，在 265 mV 的超低过电位 (η10) 和 92 mV dec-1 的塔菲尔斜率条件下，其电流密度达到了 10 mA cm-2。这一发现不仅彰显了掺镁 BCTO 的电催化效率，还将其定位为开发高活性、高稳定性水氧化催化剂的理想模型，有助于推动清洁能源技术的发展。

Aqueous zinc ion batteries are considered as a promising energy storage resource due to their high security, abundant resources and low price. However, the development of aqueous zinc ion batteries has been severely hindered by compulsive dendrite generation, serious side reactions and poor temperature adaptability. Herein, we used hydroxyethyl urea as a hydrogel electrolyte additive to address above-mentioned challenges. Hydroxyethyl urea can break the hydrogen bonds (HBs) of water and enhancing the freezing-tolerance ability of the electrolyte. Meanwhile, hydroxyethyl urea can prevent the corrosion issue and inhibition of Zn dendrites. Consequently, the Zn//Zn symmetric battery can sustain stable cycling for over 3000 h at 1 mA cm⁻², and it achieves a high coulombic efficiency of 99.6 %. Even at −40 ℃ the batteries show excellent cycling stability, the Zn//Zn symmetry battery can achieve steadily cycles over 3000 h. The Zn//NVO battery equipped with the altered electrolyte exhibits enhanced capacity retention compared to the one without additives. It demonstrates not only excellent cycling stability at room temperature but also maintains commendable functionality down to −40 ℃, validating the method’s efficacy. This work provides a simple strategy for enhancing low temperature performance of zinc ion batteries.

锌离子水电池因其安全性高、资源丰富和价格低廉而被视为一种前景广阔的储能资源。然而，由于枝晶的强制生成、严重的副反应和较差的温度适应性，锌离子水电池的发展一直受到严重阻碍。在此，我们采用羟乙基脲作为水凝胶电解质添加剂来解决上述难题。羟乙基脲可以破坏水的氢键（HBs），增强电解质的耐冻能力。同时，羟乙基脲还能防止锌枝晶的腐蚀问题和抑制作用。因此，Zn//Zn 对称电池在 1 mA cm-2 的条件下可持续稳定循环 3000 小时以上，库仑效率高达 99.6%。即使在零下 40 ℃ 的环境中，电池也能表现出卓越的循环稳定性，锌//锌对称电池可实现 3000 小时以上的稳定循环。它不仅在室温下表现出卓越的循环稳定性，而且在零下 40 ℃ 也能保持令人称道的功能，从而验证了该方法的有效性。这项工作为提高锌离子电池的低温性能提供了一种简单的策略。

Fabricating of high-performance photoanodes played an important role in achieving efficient conversion of solar energy to hydrogen energy. Herein, Al-ZnO/FeVO₄ core–shell nanorods arrays (NRs) was constructed through a simple two-step method to form type-II heterojunction. Compared with the Al-ZnO substrate (0.55 mA/cm²), the modified Al-ZnO/FeVO₄ photoanode exhibited superior photocurrent density, with an optimal photocurrent density of 1.13 mA/cm² at 1.23 V vs. RHE (AM 1.5G). Heterogeneous structures suppressed the photoinduced bulk recombination of charge carriers and improved the separation efficiency of charge carriers. More importantly, the ultra-thin FeVO₄ modification layer weakened surface capture states, increased photovoltage, and promoted interfacial charge transfer dynamics. This work provided new ideas for designing high-performance photoanodes.

制备高性能光阳极对于实现太阳能到氢能的高效转化具有重要作用。本文通过简单的两步法构建了Al-ZnO/FeVO4核壳纳米棒阵列（NRs），形成了II型异质结。与 Al-ZnO 衬底（0.55 mA/cm2）相比，改进后的 Al-ZnO/FeVO4 光阳极表现出更高的光电流密度，在 1.23 V 对 RHE（AM 1.5G）电压下，最佳光电流密度为 1.13 mA/cm2。异质结构抑制了光诱导的电荷载流子大量重组，提高了电荷载流子的分离效率。更重要的是，超薄 FeVO4 修饰层削弱了表面俘获态，提高了光电压，并促进了界面电荷转移动力学。这项工作为设计高性能光阳极提供了新思路。

The binder-free electrodes based on CuO-NiO and sodium polyacrylate-derived carbon dots (CDs) composites were simply prepared on nickel foam in two steps: hydrothermal synthesis and thermal annealing. A specific capacitance as high as 635 F g⁻¹ (at 5 mV s⁻¹) was achieved with the electrodes containing CDs embedded in the CuO-NiO nanowires, compared to only 468 F g⁻¹ for the CuO-NiO nanowire electrode without CDs, representing a 136 % improvement. To provide mechanistic insights on the supercapacitor performance, electrochemical analysis was carried out, and it was found that synergistic effects from CuO-NiO and CDs gave an optimum contribution of surface/diffusion processes of charge transfer. Asymmetric supercapacitor was also fabricated using activated carbon as a negative electrode and CDs/CuO-NiO@Ni-foam as a positive electrode, giving a 1.5 V, highest energy density of 20.3 Wh kg⁻¹ at power density of 151.1 W kg⁻¹. Due to simplicity and extraordinary performance, the binder-free CDs/CuO-NiO composite electrodes are potential candidates for the mainstream supercapacitors, and the strategy detailed in this work also provides an innovative, practical way for an electrode design for energy storage devices.

基于 CuO-NiO 和聚丙烯酸钠衍生碳点 (CD) 复合材料的无粘合剂电极是在泡沫镍上通过水热合成和热退火两个步骤简单制备的。在 CuO-NiO 纳米线中嵌入 CD 的电极的比电容高达 635 F g-1（5 mV s-1），而不含 CD 的 CuO-NiO 纳米线电极的比电容仅为 468 F g-1，提高了 136%。为了深入了解超级电容器性能的机理，研究人员进行了电化学分析，发现 CuO-NiO 和 CD 的协同效应为电荷转移的表面/扩散过程做出了最佳贡献。此外，还以活性炭为负极、CDs/CuO-NiO@Ni-foam 为正极制备了不对称超级电容器，其电压为 1.5 V，最高能量密度为 20.3 Wh kg-1，功率密度为 151.1 W kg-1。不含粘合剂的 CDs/CuO-NiO 复合电极具有简单易用、性能卓越的特点，是主流超级电容器的潜在候选材料，而本研究中详细阐述的策略也为储能设备的电极设计提供了一种创新、实用的方法。

Researchers have shown a significant amount of interest in synthesizing high energy density supercapacitors using a simplest, fast, and low cost technique. The electrochemical performance of supercapacitors can be impacted by the surface area and morphology of electrode materials. A one-step, rapid, and economical microwave-assisted synthesis technique was employed in this study in order to prepare mesoporous nanosheets that are composed of zinc sulfide. The ZnS-based nanosheets possess a large surface area of ∼120 m²g⁻¹ and a mesoporous structure of a pore diameter of <22 nm, which offers numerous electrochemical active sites and it facilitates an excellent super capacitive performance, which is due to its shortened ion/electron diffusion path. The prepared mesoporous nanosheets exhibit a higher specific capacitance of 2282 Fg⁻¹ (1037 C/g) when subjected to a 1 Ag⁻¹ in 2 M KOH aqueous electrolyte with high capability rate. The fabricated device exhibits a high specific capacitance of 252.5 Fg⁻¹ (140 C/g) at 1 Ag⁻¹, which produces a remarkable energy density of about 90 Whkg⁻¹ at 800 Wkg⁻¹ value of power density and an excellent retention of ∼95 % after 10,000 cycles at 6 Ag⁻¹. This study designed an instant, straightforward and low-cost approach to fabricate ZnS nanosheet electrode materials that exhibit excellent performance for supercapacitor applications.
