Highly stable cobalt-doped FeSe2 anodes for unexpectedly fast sodium storage enabled by doping and structure engineering SCIE
期刊论文 | 2025 | INTERNATIONAL JOURNAL OF GREEN ENERGY
Abstract&Keyword Cite Version(1)

Abstract :

Cobalt and iron selenides-based materials with high theoretical capacities, low toxicity and abundant sources have been identified as the promising anode materials for sodium-ion batteries (SIBs). However, they still face the challenges of high volume expansion and slow electrode kinetics, resulting in poor rate performance and fast capacity fading. In this paper, three-dimensional honeycomb-like Co-Fe based selenide composites with different molar ratios are successfully synthesized by one-pot solvothermal, annealing and selenization processes (expressed as Co-FeSe2@C/CNs-fbs, Co-FeSe2@C/CNs-irs and Co-FeSe2@C/CNs-sbs). Benefitted from the design of three-dimensional porous compositing structure, the optimized Co-FeSe2@C/CNs-fbs electrode material possesses more active sites and structural stability, resulting in stable cycling performance and fast electron/ion transport. As a result, Co-FeSe2@C/CNs-fbs anode shows excellent rate capability (353.1 mAh g-1 at 120 A g-1) and long cycling performance (95.7% of capacity retention after 3700 cycles at 60 A g-1), surpassing most previously reported anode materials for SIBs. Meanwhile, a full-cell made up with Na3V2(PO4)3/C cathode and Co-FeSe2@C/CNs-fbs anode shows a high energy density (180.1 Wh kg-1 at a power density 630.5 W kg-1) and capacity retention rate. This study provides a feasible strategy to fabricate selenide-based composites as the anode materials for high-performance SIBs via doping and structure engineering.

Abstract :

Constructing the continuously-distributed and crystalline-NaF-rich solid electrolyte interface (CC-NaF-SEI) is expected to greatly promote the sodium storage performance of hard carbon (HC) anodes. However, such an impressive concept remains extremely intractable to achieve and lacks an efficiently cost-less strategy. Herein, the application of the commercially available LA133 binder is pioneered to engineer such a CC-NaF-SEI. Through comparative analysis of representative binders with distinct functional groups, reveals the critical role of binder chemistry on SEI regulation. Specifically, the LA133 binder demonstrates a dual-regulation mechanism for CC-NaF-SEI formation. The anion-coordination preferred ─CN bonds induce an anion-enriched interfacial solvation structure, and the ─CONH/─CN groups catalytically cleave P─F bond dissociation in PF6−, synergistically promoting anion decomposition kinetics to form crystalline NaF. Furthermore, robust hydrogen bonds between multiple polar groups in LA133 and HC surface create the spatially anion-confined microenvironments to guide orderly anion decomposition and facilitate continuous NaF growth into a mechanically integrated SEI. The optimized CC-NaF-SEI endows HC anodes with exceptional sodium storage performance: an ultrahigh initial Coulombic efficiency (95.9%), remarkable reversible capacity (356.6 mAh g−1), and stable cycling under extreme conditions (−20–60 °C). This work provides fundamental insights into binder-SEI correlations, establishing a novel paradigm for interfacial optimization in sodium-ion batteries. © 2025 Wiley-VCH GmbH.

Abstract :

Anode-free solid-state lithium (Li) metal batteries (AFSSLMBs), with anticipated high energy density and cost-effectiveness, high safety, and simplicity of fabrication, are considered to have great potential in becoming promising alternatives for next-generation electrochemical energy storage devices. Unfortunately, the inefficiency of Li plating/stripping and the rapid capacity decay during cycling have severely hindered the further development of AFSSLMBs. Accordingly, to cope with these faced challenges, enormous efforts have been made in the most recent years. However, a comprehensive review entirely focusing on AFSSLMBs seems not available in terms of the loss and recovery of effective Li. Herein, based on the current understanding of AFSSLMBs, the essential causes of the main challenges faced by AFSSLMBs are attributed to irreversible Li loss and sluggish Li kinetics. Subsequently, five main types of advanced strategies for promoting AFSSLMBs' performance from various critical components are categorized and summarized along with the main line of avoiding effective Li loss, in which the contents from impactful articles published in the most recent one to two years are predominantly comprised. Finally, the challenges and possible future directions of AFSSLMBs are proposed, aiming to accelerate the rapid research and development for practical applications and commercialization of this advanced technology.

Bifunctional Pt/TiO2-Ov catalysts for enhanced electron transfer and CO tolerance in acidic HOR and ORR SCIE
期刊论文 | 2025 | FRONTIERS IN ENERGY
Abstract&Keyword Cite Version(1)

Abstract :

The development of anti-corrosion and anti-poison electrocatalysts for both the hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR) is of great importance for effective applications of proton exchange membrane fuel cells (PEMFCs). In this study, a non-carbon supported catalyst, Pt/TiO2-O-v, enriched with oxygen vacancies (O-v), is successfully synthesized using a microwave-assisted method. This catalyst is developed as a bifunctional electrocatalyst with superior contamination tolerance, enabling efficient HOR and ORR performance. The electronic metal-support interaction (EMSI) is leveraged to facilitate electron transfer between Pt and Ti atoms, induced by the formation of oxygen vacancy channels in the small-sized, high surface area TiO2-O-v support. Notably, TiO2-O-v has a lower bandgap than commercial TiO2, enhancing its catalytic properties. In a 0.1 mol/L HClO4 electrolyte, the normalized Pt mass activity (j(k,m)) and specific activity (j(0,s)) of Pt/TiO2-O-v are 1.24 times higher than those of commercial Pt/C. Furthermore, Pt/TiO2-O-v catalyst exhibits minimal current density decay after a prolonged durability testing under hydrogen and oxygen atmospheres. Remarkably, under a H-2/(1000x10(-6)) CO atmosphere, the relative retention rate of Pt/TiO2-O-v significantly exceeds that of Pt/C catalyst, demonstrating its superior CO tolerance and promising potential for practical applications in PEMFCs. This study highlights the critical role of the strong metal-support interaction between the reducible oxide support and the noble metal Pt in improving long-term performance and CO poisoning resistance.

Abstract&Keyword Cite Version(1)

Abstract :

Flexible lithium-ion batteries (FLIBs) have garnered significant research interest as critical energy storage components, driven by rapid advancements in deformable electronic systems. However, it is a challenge to simultaneously realize adequate flexibility, stability, and energy density for FLIBs. Cellulose-based materials demonstrate inherent flexibility, lightweight characteristics, high surface area, and cost-effectiveness, enabling their promising utilization in electrode architectures for high-energy-density flexible battery systems. In this review, we summarize the recent research progress of the application of cellulose-based materials in FLIBs, with special emphasis on roles of cellulose-based materials in electrodes of FLIBs. Firstly, the roles of cellulose-based materials in FLIBs' anodes are categorized into four distinct types: precursor, binder, skeleton, and modification layer, accompanied by an overall review of recent advances. Similarly, their multifunctional contributions in FLIBs cathodes are also systematically classified into three categories: binder, skeleton, and modification layers, with corresponding progress in each domain comprehensively summarized. Finally, the challenges and possible future directions of cellulose-based materials in FLIBs are proposed, aiming to accelerate the rapid research and development for practical applications and commercialization of this advanced technology.

Dual-Enhanced Charge Transfer through Prelithiation Strategy in Polymer Electrolyte Enables Robust LiF-Rich SEI for Ultralong-Life All-Solid-State Batteries SCIE

Abstract&Keyword Cite Version(1)

Abstract :

Lithium fluoride (LiF)-rich solid electrolyte interface (SEI) is critical for enabling the stable operation of polymer-based all-solid-state lithium-metal batteries (ASSLMBs). Precisely controlling the C & horbar;F dissociation chemistry in fluorine-containing lithium salts to construct a LiF-rich SEI is a logically viable but still challenging approach. Current strategies for constructing LiF-rich SEI primarily focus on designing non-metal polar groups and related structures. In contrast, approaches leveraging metal-based electron donors to facilitate charge transfer for C & horbar;F bond cleavage and LiF formation remain largely unexplored. Herein, a dual-enhanced charge transfer mechanism through prelithiation strategy is proposed in solid polymer electrolyte (SPE) for C & horbar;F bond cleavage. The charge transfer occurs between LiTFSI and the introduced metal sites and further enhanced by lithiation design, thereby achieving a robust LiF-rich SEI. The achieving SPEs enable an excellent cyclability of Li|Li cell over 3800 h at 0.3 mA cm-2. Li||LiFePO4 ASSLMBs demonstrate a high Coulombic efficiency of approximate to 100% and a stability of 1200 cycles with capacity retention of 80% at 2C. The corresponding pouch cell delivers a high average areal capacity of 2.41 mAh cm-2 over 1600 h. This work offers a novel approach for constructing LiF-rich SEI toward durable ASSLMBs.

Abstract :

Introducing advanced conductive nanoparticles to combine with metal-organic frameworks (MOFs) as electrode is emergingly regarded as a practical and efficient approach to improve the capacitive performance of super- capacitors. Herein, a new MOF (ZrNi-UiO-66, Nickel-zirconium 1,4-dicarboxybenzene) is designed to combine with carbon quantum dots (CQDs) to form a composite electrode with high specific capacitance, in which the charge regulation is performed to facilitate the electronic conduction and transfer. Such constructed electrode delivers an enhanced electronic conductivity and an improved specific capacitance of 2468.75 F g- 1 @ 1 A g- 1 , which is four times of the contrast sample. Meanwhile, the assembled hybrid supercapacitor exhibits an increased energy density and power density, as well as a sustainable stability after 10,000 cycles with a retention rate of 91.6 %. Basing on the study of advanced characterizations and density functional theory (DFT) simulation, the mechanism of significantly improved specific capacitance can be elaborated as the promote electronic conduction caused from narrowed band gap from 3.9 eV or 0.41 eV-0.23 eV, and the increased charge accumulation at the Ni sites in designed MOFs. This work provides new insights for the design and construction of potential energy storage materials based on MOFs and/or advanced carbon-based materials.

Abstract :

ZnO with good lithiophilicity has widely been employed to modify the lithiophobic substrates and facilitate uniform lithium (Li) deposition. The overpotential of ZnO-derived Li anode during cycling depends on the lithiophilicity of both LiZn and Li2O products upon lithiation of ZnO. However, the striking differences in the lithiophilicity between Li2O and LiZn would result in a high overpotential during cycling. In this research, the Al2O3/nZnO (n >= 1) hybrid layers were precisely fabricated by atomic layer deposition (ALD) to regulate the lithiophilicity of ZnO phase and Li2O/LiZn configuration-determining the actual Li loading amount and Li plating/stripping processes. Theoretically, the Li adsorption energy (E-a) values of LiZn and Li2O in the LiZn/Li2O configuration are separately predicted as -2.789 and -3.447 eV. In comparison, the E-a values of LiZn, LiAlO2, and Li2O in the LiZn/LiAlO2/Li2O configuration upon lithiation of Al2O3/8ZnO layer are calculated as -2.899, -3.089, and -3.208 eV, respectively. Importantly, a novel introduction of LiAlO2 into the LiZn/Li2O configuration could enable the hierarchical Li plating/stripping and reduce the overpotentials during cycling. Consequently, the Al2O3/8ZnO-derived hybrid Li-metal anode could exhibit electrochemical performances superior to these of ZnO-derived Li anode in both symmetrical and full cells paired with a LiNi0.6Co0.2Mn0.2O2 (NCM622) cathode.

Surface electron reconfiguration of ceric dioxide artificial interface layer by cationic doping for dendrite-free zinc anode SCIE

Abstract&Keyword Cite Version(2)

Abstract :

Aqueous zinc metal batteries (ZMBs) are regarded as strong contenders in secondary battery systems due to their high safety and abundant resources. However, the cycling performance of the Zn anode and the overall performance of the cells have often been hindered by the formation of Zn dendrites and the occurrence of parasitic side reactions. In this paper, a surface electron reconfiguration strategy is proposed to optimize the adsorption energy and migration energy of Zn2+ for a better Zn2+ deposition/stripping process by adjusting the electronic structure of ceric dioxide (CeO2) artificial interface layer with copper atoms (Cu) doped. Both experimental results and theoretical calculations demonstrate that the Cu2Ce7Ox interface facilitates rapid transport of Zn2+ due to the optimized electronic structure and appropriate electron density, leading to a highly reversible and stable Zn anode. Consequently, the Cu2Ce7Ox@Zn symmetric cell exhibits an overpotential of only 24 mV after stably cycling for over 1600 h at a current density of 1 mA/cm2 and a capacity of 1 mAh/cm2. Additionally, the cycle life of Cu/Zn asymmetric cells exceeds 2500 h, with an average Coulombic efficiency of 99.9%. This paper provides a novel approach to the artificial interface layer strategy, offering new insights for improving the performance of ZMBs.

Abstract :

High-temperature proton exchange membrane fuel cells (HT-PEMFCs) show broad application perspectives due to their faster reaction kinetics and tolerance to fuel/gas impurities as well as the easy water/heat managements. However, the catalysts and subsequent membrane electrode assemblies (MEAs) are still suffering from performance degradation, which severely restricts HT-PEMFCs' large-scale practical application. To overcome the challenges, developing high-performance catalysts and MEAs with advanced materials and optimized structures to achieve stable and efficient operation of HT-PEMFCs is necessary. To facilitate the research and development of HT-PEMFCs, a comprehensive overview of the latest developments in the design of active and stable catalysts and durable MEAs is presented in this paper. This review systematically summarizes the degradation mechanisms of catalysts, and corresponding mitigation strategies for improving the stability of catalysts and MEAs, aiming to effectively developing high-performance and durable HT-PEMFCs. Furthermore, the main challenges are analyzed and the future research directions for overcoming the challenges are also proposed for developing highactive and stable catalysts and MEAs used in HT-PEMFCs toward practical applications.
