Binder-Free NiCo(PO4)3 Nanosheet Electrode for Supercapattery With Enhanced Ion Transport and Long-Term Stability Usman Ahmed, Faiza Bibi, Adnan Younis, Fawad Ahmad, Seitkhan Azat, Arshid Numan, Fathalla Hamed Battery Energy, 2026 Binder‐free electrodes are emerging as a transformative solution in electrochemical energy storage systems, offering direct electron transport pathways and eliminating the limitations imposed by insulating binders. In this work, we report the synthesis of nickel‐cobalt phosphate dihydrate (NCP) grown directly on nickel foam using a simple hydrothermal method carried out at 180°C for 12 h. This straightforward approach yielded a distinctive flake and nanosheet morphology, resulting in abundant electroactive sites, enlarged surface area, and open channels for rapid ion diffusion. Electrochemical investigation revealed the remarkable performance of the NCP electrode. Cyclic voltammetry (CV) demonstrated a specific capacity of 118.8 C/g (215 F/g) at 5 mV/s, while galvanostatic charge‐discharge (GCD) measurements confirmed a specific capacity of 98.8 C/g (178.9 F/g) at 1 A/g within a 0.55 V potential window. To evaluate practical applicability, a supercapattery device was assembled using the binder‐free NCP electrode as the positive electrode and activated carbon (AC) as the negative electrode. The NCP//AC device delivered a specific capacity of 87.7 C/g at 0.5 A/g. Most notably, the device demonstrated outstanding electrochemical stability, maintaining 92.9% capacity retention after 5000 cycles at 2 A/g. These findings highlight the efficacy of the hydrothermal approach and the synergistic role of Ni and Co in stabilizing the phosphate framework. The NCP electrode, with its unique nanosheet architecture, emerges as a promising candidate for next‐generation, high‐performance supercapattery.
Single-Crystal NCM-Enabled Multifunctional Separator Design for High-Performance Lithium-SPAN Batteries Ammaiyappan Anbunathan, Yi‐Shiuan Wu, Jeng‐Kuei Chang, Arshid Numan, Sayee Kannan Ramaraj, Rajan Jose, Chun‐Chen Yang Small, 2026 High‐energy and sustainable batteries are key to a low‐carbon future, and lithium‐sulfur (Li‐S) systems stand out for their high energy density, abundance, and low cost. Organo‐polymer cathodes such as sulfurized polyacrylonitrile (SPAN) cathodes offer solid‐state conversion and suppress polysulfide shuttling, yet their sluggish redox kinetics and limited active material utilization hinder practical performance. Herein, we introduce a multifunctional trilayer mixed‐conduction separator that synergistically integrates ionic selectivity, kinetic facilitation, and interfacial stabilization. The separator, composed of single‐crystal NCM811 (SC‐NCM), BP2000 carbon, and Li‐Nafion binder sandwiched between two polypropylene separators (PP|SC‐NCM|PP), forms Li + ‐ion transport channels, interfacial charge redistribution, and promotes stable solid‐state redox reactions (S to Li 2 S) within the SPAN cathode. This architecture enhances Li + transference number (0.60), ionic conductivity (1.82 × 10 −3 S·cm −1 ), and electrolyte uptake (68%), while suppressing thermal shrinkage and self‐discharge. As a result, the cells deliver an initial discharge capacity of 1779 mAh·g −1 at 0.1C, retains 80% capacity after 500 cycles (1C), and sustain 771 mAh·g −1 at 10C (high‐rate capability). This scalable, recyclable, and multifunctional separator offers a sustainable route to high‐performance Li‐S batteries and sets a precedent for mixed‐conduction membrane designs in next‐generation energy‐storage technologies.
Synergistic Interfacial Engineering of ZnO-Modified Cu Current Collectors Using Lithium Trithiocyanurate for Stable Anode-Free Lithium Metal Batteries Yueh‐Hsuan Chiang, Ammaiyappan Anbunathan, Yi‐Shiuan Wu, JinKiong Ling, Jeng‐Kuei Chang, Jenn‐Shing Chen, Arshid Numan, Chun‐Chen Yang Chemsuschem, 2026 Anode‐free lithium metal batteries (AFLMBs) promise high‐energy‐density, cost‐efficient storage by removing excess lithium at anode side, yet their practical use is limited by uncontrolled Li nucleation, continuous Li loss, and unstable Cu interfaces. We report a synergistic interfacial strategy using a lithiophilic ZnO‐modified Cu current collector with a lithium trithiocyanurate (Li‐TCA) coating to stabilize Li deposition and regulate Li + transport on the solid electrolyte interphase (SEI). The ZnO bottom layer provides uniform nucleation sites, lowering the Li nucleation barrier, while the Li‐TCA top layer acts as a Li reservoir and interfacial regulator, mitigating early Li depletion and enhancing stability. Optimized 5%Li‐TCA@60%ZnO@Cu anodes exhibit markedly improved Li reversibility and reduced polarization, delivering an ultralow initial plating/stripping overpotential of 12.8 mV, compared to 40.9 mV for ZnO@Cu and 76.1 mV for bare Cu. Paired with high‐mass‐loading LiFePO 4 cathodes (~17 mg cm −2 ), these anode‐free full cells show enhanced initial Coulombic efficiency and cycling stability, retaining 56.2% capacity after 100 cycles versus 47.8% and 34.6% for ZnO@Cu and bare Cu, respectively. scanning electron microscopy and X‐ray photoelectron spectroscopy analyses confirm uniform Li deposition, suppressed dead Li, and stabilized SEI, validating the dual‐function design. This scalable strategy addresses Li nucleation, SEI stability, and Li inventory, offering a promising route toward practical AFLMBs.
Composite Polymer Electrolyte Membrane for Efficient Anodic and Cathodic Processes for Quasi-Solid-State Lithium–Oxygen Batteries Azhagar Samy, Bo-Rong Zhang, Raja Palani, Yi-Shiuan Wu, She-Huang Wu, Jeng-Kuei Chang, Arshid Numan, Rajan Jose, Chun-Chen Yang ACS Applied Energy Materials, 2026 Solid-state lithium–oxygen batteries are intensively researched for their superior energy density, operational stability, and safety over the liquid electrolyte analogues; however, they face several crucial challenges, such as instability of the lithium anode and high interfacial resistance for efficient oxygen redox reactions at the cathode. In this study, we designed and optimized a bilayer electrolyte membrane to protect the anode and facilitate efficient oxygen reduction (ORR) and oxygen evolution (OER) reactions at the cathode. The anode side had a copolymer (PVDF–HFP) with a lithium salt (LiTFSI), while the cathode side additionally contained varying amounts of LiTa 2 PO 8 (LTPO) as solid electrolyte and SN as a plasticizer. The quasi-solid-state lithium–oxygen battery (QSSLOB) fabricated using the bilayer membrane having 20 wt % of LTPO, a small amount (∼30 μL) of liquid electrolyte (1 M LiTFSI/0.5 M LiI in TEGDME) at the cathode side delivered a discharge capacity (∼6885 mAh g –1 ), excellent rate capability, and stable cycling (>424 cycles/100 mA g –1 and 105 cycles/300 mA g –1 at 25 °C) and outperformed several other control devices and reported QSSLOBs. A series of tests and inspections were undertaken to determine the factors contributing to the superior performance of the optimized device; together, these studies revealed a wide electrochemical stability window, superior lithium diffusion coefficient, favorable lithium transference number, excellent interfacial stability, and facile discharge–charge kinetics, leading to efficient lithium-ion transport and oxygen redox reactions, reduced oxygen crossover, and stable solid electrolyte interphase. The approach hereby could be a step forward for deployable LOBs in the beyond-lithium-ion battery scenario.
Scalable fabrication of NiCo(PO4)3 on carbon cloth: Toward next-gen flexible electrochemical energy storage devices Usman Ahmed, Faiza Bibi, Adnan Younis, Arshid Numan, Fawad Ahmad, Fathalla Hamed Journal of Physics and Chemistry of Solids, 2026 The excellent redox properties and high electrical conductivity of transition metal phosphates have shown exceptional contribution as electrochemical energy storage materials. In this study, nickel cobalt phosphate (NiCo(PO 4 ) 3 ) nanostructures were directly grown on flexible carbon cloth (CC) through a simple and cost-effective hydrothermal process, enabling the fabrication of a binder-free and mechanically robust electrode. The prepared NiCo(PO 4 ) 3 @CC electrode exhibits outstanding electrochemical performance in a three-electrode system using 1 M KOH, delivering a high specific capacity of 117 C/g at 0.4 A/g and an areal capacitance of 59.80 F/cm 2 at 10 mV/s. Notably, the asymmetric device (NiCo(PO 4 ) 3 @CC//AC), remained stable over a wide-operating potential of 1.5 V, delivering a maximum specific capacity of 96.16 C/g, and excellent cycling durability with 79.1% retention after 8000 cycles. This work highlights the synergistic integration of redox-active bimetallic phosphate with a conductive and flexible carbon cloth-based substrate, offering an effective pathway for high-performance, flexible, and wearable electrochemical energy storage devices. • NiCo(PO 4 ) 3 nanostructures were directly grown on flexible carbon cloth • Binder-free electrode fabricated through a simple hydrothermal method • High specific capacity of 215 F g -1 at 0.4 A g -1 in 1 M KOH electrolyte • Excellent cycling stability with 85 % retention after 8000 cycles • Promising flexible electrode for next-generation energy storage devices
