However, their application has been constrained by limited operational voltage windows. A high-voltage-resistant Ti-graphene-Ti cathode current collector (TGT) was designed and fabricated by three-dimensional (3D) printing. The surface of the TGT has a Ti_xO_y protective layer, which effectively suppresses electrolyte decomposition under high voltage conditions so that the voltage window of the battery is extended to 1.0–2.2 V without the obvious formation of by-products. Simultaneously, the graphene layer in the TGT structure significantly improves the adsorption and insertion/extraction kinetics of cations, resulting in a high specific capacity of 307.5 mAh g⁻¹ and a prolonged cycling life of the battery. The resultant AZIBs have a stable charge/discharge performance over 400 cycles at a high voltage. Furthermore, the influence of the geometric arrangements of Ti and graphene in the 3D printing process on the energy storage mechanism was investigated and provided novel insight for the development of high-voltage-resistant composite cathode current collectors for AZIBs.\u0000\t\t\t\t<span><figure><span><img><ol><li><span><span>Download: <span>Download high-res image (151KB)</span></span></span></li><li><span><span>Download: <span>Download full-size image</span></span></span></li></ol></span></figure></span></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"41 3","pages":"Pages 641-651"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148529416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Moiré-like morphology was engineered by the insitu deposition of lignin carbon onto DVD matrix onto lignin carbon for the fabrication of a photo-assisted supercapacitor (PASC). The Moiré-like structure modulates light propagation across different frequencies by dispersion effects, thereby increasing surface light absorption and improving the electrochemical performance of the PASC. Under illumination, the carbon has a specific capacitance of 253.5 F g⁻¹ at 0.5 A g⁻¹, corresponding to a 35.6% improvement over one without this grating surface (186.9 F g⁻¹). A symmetrical capacitor using this material has an areal capacitance of 58.84 mF cm⁻² and an energy density of 4.46 Wh kg⁻¹ at a power density of 365.2 W kg⁻¹, maintaining 85.2% of its initial capacitance after 5000 cycles, thus demonstrating excellent cycling stability.

Spinnable pitches with low and high softening points (L-SP and H-SP) were prepared by air-blowing thermal polymerization of coal tar pitch. The polymerization mechanism, structural composition, properties of the pitch, and the carbon fiber properties were investigated by fluorescence excitation-emission spectroscopy with parallel factor analysis, EPR, ¹³C-NMR, dynamic shear rheometry, XRD, Raman, etc. L-SP had the lower degree of polymerization, longer alkyl side chains, and a higher proportion of C―O―C groups. At its spinning temperature, the molten L-SP had viscous-dominant rheological characteristics. H-SP had larger polycyclic aromatic hydrocarbon rings, a higher degree of branching, and a higher polarity. The molten H-SP had a high storage and loss moduli, and a rheological behavior with nearly balanced viscous and elastic properties. Although carbon fibers prepared from H-SP had the better physical properties, their inferior rheological properties could lead to melt die swelling, the formation of surface particles and an increased number of irregularities. The superior viscoelasticity of L-SP promoted uniform stretching, maximizing the properties of carbon fibers. This ultimately resulted in similar tensile strengths and moduli of the carbon fibers prepared from the two pitches. The high-quality spinnable pitch had a high aromatic carbon content, a small size of its PAHs, and a low C=O/O—C=O content, which ensured viscosity-dominated rheological behavior, thereby reducing die swelling and melt fracture, and the spinning stability and properties of the carbon fibers produced were improved.\u0000\t\t\t\t<span><figure><span><img><ol><li><span><span>Download: <span>Download high-res image (322KB)</span></span></span></li><li><span><span>Download: <span>Download full-size image</span></span></span></li></ol></span></figure></span></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"41 3","pages":"Pages 721-736"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148544117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reconstructed NiOOH phase plays a critical role in improving the oxygen evolution reaction (OER) performance of NiFe-based LDHs, but observing the NiOOH phase is difficult because of its instability and exploring the functional mechanism of NiOOH in NiFe-based LDHs remains a great challenge. A simple electrochemical activation was used to synthesize a NiOOH/NiFeV-LDH@CC catalyst consisting of an array of V-doped NiFe-LDH nanosheets on carbon cloth (CC), in which the reconstructed NiOOH phase is the active species. During electrochemical activation, the release of doped V leads to the formation of abundant vanadium vacancy (V_V) and oxygen vacancy (V_O) species, and thus the surface of the NiFe-LDH nanosheets is reconstructed to form NiOOH. Because of the improved intrinsic activity from the NiOOH active phase, and the increased electrical conductivity produced by the abundant V_O, NiOOH/NiFeV-LDH@CC has an excellent OER performance in an alkaline solution, with low overpotentials of 209 mV and 241 mV at 20 mA cm⁻² and 100 mA cm⁻², respectively. It also has a long-term stability of 80,000 s at a constant current density of 10 mA cm⁻². Using NiOOH/NiFeV-LDH@CC as the anode, an assembled over water splitting (OWS) battery can drive a current density of 20 mA cm⁻² (without iR compensation) at a much lower voltage of 1.597 V. At the same time, the electrolytic cell can deliver a current density of 10 mA cm⁻² at ~1.55V for more than 80,000 s without significant loss. This electrochemical activation method can be used in future designs of electrocatalysts for OER.\u0000\t\t\t\t<span><figure><span><img><ol><li><span><span>Download: <span>Download high-res image (154KB)</span></span></span></li><li><span><span>Download: <span>Download full-size image</span></span></span></li></ol></span></figure></span></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"41 3","pages":"Pages 664-673"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148529407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, high fluorine doping levels often lead to reduced surface polarity and electrolyte wettability, which limits their applicability. Herein, fluorine-doped carbon nanosheets with both a high fluorine content (6.10%, atomic percent) and amphiphilicity were fabricated from ethylene tar pitch by a novel microwave-assisted ionic liquid intensification strategy within a remarkably short time (20 min). During microwave treatment, the ionic liquid served as a heating medium, enabling a rapid temperature increase (100 °C min⁻¹) through microwave absorption, thus ensuring efficient synthesis. When this material is used as a separator coating, the electrolyte wettability is much better. Meanwhile, the inherent covalent C―F bonds facilitate the formation of a LiF-rich solid electrolyte interphase layer upon lithiation, promoting uniform lithium deposition and suppressing dendrite growth as well as the formation of dead Li. The assembled lithium metal batteries had a high Coulombic efficiency retention (≥98.9% after 1200 cycles), ultra-long cycling stability (3400 h at 1 mA cm⁻²) and excellent full battery performance.

The co-impregnation treatment resulted in a specific surface area of the MBC that was approximately 54 times greater than that of the biochar derived from untreated stalks. The ion-exchange capacity of MBC was increased by the incorporation of MgO nanoparticles, which increased the alkali metal ion (Mg²⁺) content. These specific structures and compositions gave the MBC a high adsorption capacity for Pb(II) and Cd(II). The adsorption data followed a quasi second-order kinetic model. For Cd(II) and Pb(II), the maximum adsorption capacities of MBC-700 (treated at 700 °C for 2 h) reached 520 mg/g and 808 mg/g, respectively. The primary adsorption mechanisms were ion exchange, precipitation, electrostatic attraction and surface complexation. Furthermore, metallic lead was recovered by using the reducing properties of the biochar at high temperatures.
