Abstract&Keyword Cite

Abstract :

The development of metal-based materials for supercapacitor electrodes garners significant attention in energy storage research due to their potential to achieve high energy and power density. This study presents a one-step solvothermal synthesis of nickel-cobalt bimetallic chlorides (NCC) with ethanol as the solvent. By precisely tuning the Cl-content, the material's structural, morphological, and electrochemical properties are optimized. Among the synthesized samples, NCC-8, prepared with a Ni:Co:Cl molar ratio of 1:1:8, demonstrates superior performance, delivering a remarkable specific capacitance of 1385.4 F g- 1 at 1 A g- 1, which is more than twice that of its chloride-free counterpart. Furthermore, an asymmetric supercapacitor (NCC-8//AC), constructed with NCC-8 as the positive electrode and activated carbon (AC) as the negative electrode, achieves an exceptional energy density of 80.1 Wh kg- 1 at a power density of 800 W kg- 1. The device also exhibits excellent cycling stability, retaining 74.1 % of its initial capacitance after 10,000 charge-discharge cycles at 10 A g- 1. These findings highlight the potential of chloride-ion-modified nickel-cobalt materials as high-performance electrode candidates, paving the way for developing next-generation energy storage systems with enhanced longevity and superior performance.

Abstract :

B/N co-doped porous carbons (BNCs) with abundant micropores were developed by a microwave-introduced heating and activator-free strategy. The thermal decomposition of the dopant NH4B5O8 & sdot;4 4 B 5 O 8 & sdot; 4 H2O) 2 O) creates well- developed micropore architecture in BNC-180, achieving a remarkable specific surface area of 891 m 2 g- 1 and a pore volume of 0.46 cm3 3 g- 1 , significantly surpassing the non-doped sample C-180 (605 m 2 g-- 1 ). Additionally, incorporating high levels of B and N into the carbon skeleton modified the functional group species and electron distribution, enhanced electrical conductivity, and boosted electrochemical performance. Compared with C-180 (93.0 F g-- 1 ), the as-prepared BNC-180 manifests a specific capacitance of 219.0 F g- 1 at 0.5 A g- 1 in a three-electrode configuration with a striking rate performance of 83.8 % at 10 A g- 1 , implying that the porosity and surface chemical functional groups play a crucial role. Furthermore, the as-built symmetric supercapacitor shows a pronounced energy density of 13.4 Wh kg- 1 at 375 W kg- 1 , and still remained 10 Wh kg- 1 at 7500 W kg- 1 . The excellent durability was demonstrated by the outstanding cycling stability with a specific capacitance retention of 87.84 % after 20,000 cycles.

Abstract :

Cobalt-nickel metal-organic framework/activated carbon (MOF/AC) composites with tunable flower-like architectures were synthesized via a straightforward hydrothermal method, utilizing activated carbon as a structural and functional modifier. This modification increased the surface area from 20.3 m2/g to 164.5 m2/g, providing a high density of nucleation sites and optimizing the morphology for efficient ion diffusion and electrolyte permeability. The incorporation of activated carbon (AC) not only improved structural stability but also facilitated electron transfer, thereby enhancing conductivity. Among the synthesized composites, MOF/AC180 exhibited a specific capacitance of 731.8 F/g at 1 A/g, with 67.0 % retention at higher current densities. An asymmetric supercapacitor (ASC) based on MOF/AC-180 achieved an energy density of 35.9 Wh/kg at a power density of 750 W/kg, along with considerable cycling stability, retaining 91 % of its initial capacitance after 10,000 cycles. This study highlights the potential of using AC to enhance the structure and conductivity of MOF composites. The tunable morphology improves ion transport and electrochemical performance, making these materials viable for supercapacitor applications. Furthermore, the straightforward synthesis method and scalability provide a basis for future industrial applications across various multifunctional material fields.

Abstract :

Nickel-cobalt bimetallic sulfides are promising electrode materials for hybrid supercapacitors due to their high theoretical capacity and abundant active sites, but their practical application is limited by poor electrical conductivity and structural instability during cycling. To address these challenges, hierarchical chrysanthemum-shaped Co3S4@Ni3S4@C heterostructures were successfully synthesized via a two-step hydrothermal method using bamboo-derived porous carbon (BNA600). The resulting Co3S4@Ni3S4@C heterostructure exhibited significantly enhanced electrochemical performance, achieving a high specific capacitance of 1016.8 F g-1 at 1 A g-1 in a three-electrode system, along with superior rate capability (80.4 % retention at 10 A g-1). Benefiting from the hierarchical porous morphology, conductive carbon matrix, and optimized electron transport pathways at the heterogeneous interfaces, the assembled hybrid supercapacitor (Co3S4@Ni3S4@C cathode and bamboo-derived porous carbon anode) delivered an ultrahigh energy density of 68.13 Wh kg-1 at a power density of 749.8 W kg-1 and maintained an outstanding energy density of 51.25 Wh kg-1 even at a high power density of 7500 W kg-1, surpassing most previously reported hybrid supercapacitors. Additionally, the device exhibited excellent cycling stability, retaining 89.2 % of initial capacitance after 5000 cycles at 20 A g-1. These results highlight the considerable potential of Co3S4@Ni3S4@C heterostructures derived from bamboo carbon for advanced electrochemical energy storage applications.

Abstract&Keyword Cite

Abstract :

Nickel-cobalt layered double hydroxides (NiCo-LDHs) are considered highly promising electrode materials for supercapacitors (SCs). Nevertheless, their limited conductivity and inherent stacking defects lead to inactive electronic states, thereby constraining their electrochemical performance. Here, a dual-conductive-engineered flexible electrode is fabricated through synergistic integration of in situ constructed 3D porous LDH with Ti3C2Tx nanosheets deposition, establishing a semi-confined reaction microenvironment. The collaborative conductive architecture and confinement-enhanced effects enable continuous modulation of Faradaic reaction kinetics during charge/discharge processes, achieving breakthrough improvements in both energy density and cycling stability. The optimized Ti3C2Tx/LDH/CC-50 electrode delivers a remarkable specific capacitance of 1598.7 F g(-)(1) at 1 A g(-)(1), along with excellent rate performance of 87.2% (10 A g(-1)). Furthermore, the constructed aqueous asymmetric supercapacitor (ASC) delivers an impressive energy density of 72.4 Wh kg(-)(1) and remarkable cycling stability (90.5% retention after 10 000 cycles). A flexible solid-state asymmetric SC (FSASC) is also fabricated, showcasing a significant energy density of 83.9 Wh kg(-)(1) at 900 W kg(-)(1) with excellent mechanical flexibility. DFT simulations further revealed enhanced electron transport and a greater number of active sites due to the reduced energy barrier. This work contributes new insights into the structural design of LDH/MXene nanohybrid electrodes for advanced energy density supercapacitors.

Abstract :

In this study, tannin-derived porous carbon (TAC) with different microstructures was prepared via a microwave hydrothermal method, followed by KOH activation. Subsequently, the sea urchin-like NiCo-LDH/Tannin-derived carbon-based microsphere composite materials were rationally synthesized through a single-step microwave hydrothermal co-assembly process. The physicochemical characteristics and supercapacitive performance were systematically analyzed. TAC with a microspherical structure promoted and controlled the growth of LDHs, resulting in a more regular sea urchin-like structure, improved dispersibility, reduced resistance, and increased active sites. NiCo-LDH@TAC600-0 (without KOH activation) as an electrode material delivered a specific capacitance (Cs) of 1250 F g(-1) at 1 A g(-1) and 1035 F g(-1) at 10 A g(-1), with a rate performance of 82.8%. The asymmetric supercapacitor device using NiCo-LDH@TAC600-0 and TAC provided an energy density of 30.8 Wh kg(-1) at 800 W kg(-1) and a capacitance retention rate of 72.5% after 5000 cycles. This study offers a novel approach to enhancing NiCo-LDH properties for efficient energy storage.

Abstract&Keyword Cite

Abstract :

This study demonstrates the synthesis and application of nitrogen-doped tannin carbon dots (TCDs) derived from condensed tannin of grapestone through a single-step hydrothermal method. The TCDs were employed to enhance the electrical conductivity, active site availability, structural stability, and charge storage mechanisms of NiCo-LDH composite electrodes. Density Functional Theory (DFT) calculations reveal that the incorporation of TCDs increases the density of states (DOS) near the Fermi level, thereby improving charge transport properties and contributing to the enhanced cycling stability. In a three-electrode system, the NiCo-LDH@TCDs3.0 electrode exhibits an exceptional specific capacitance of 1804.2F g-1 at 1 A g-1, with a capacitance retention of 77.4 % at a high current densities of 10 A g-1. As button cell of asymmetric supercapacitor (ASC) assembled with tanninbased activated carbon (TAC600-4) as the negative electrode and NiCo-LDH@TCDs3.0 as the positive electrode, the device demonstrates a maximum energy density of 87 Wh kg-1 at a power density of 800 W kg-1, and maintains a high energy density of 61.6 Wh kg-1 even at an ultra-high power density of 8000 W kg-1, significantly surpassing devices composed solely of NiCo-LDH. Durability assessments further revealed 78.6 % capacitance retention and 100.9 of coulombic efficiency after 10,000 cycles, underscoring its applicability in high-performance energy storage. This study not only advances the synthesis of carbon dots from sustainable tannin sources but also provides valuable insights into optimizing the specific capacitance, rate capability, and cycling durability of LDH-based supercapacitors.

Abstract&Keyword Cite

Abstract :

Biomass-derived materials have garnered significant attention as sustainable anode candidates for lithium-ion batteries (LIBs) owing to their abundance, low cost, and environmental benefits. Among these, Cenchrus fungigraminus (JUJUNCAO) stands out due to its rapid growth, high yield, and exceptional environmental adaptability, making it a promising precursor for carbon-based electrodes. In this study, activated carbon was synthesized from JUJUNCAO through a two-step process involving carbonization and KOH activation. By systematically varying the activation temperature and the biochar/KOH weight ratio, we precisely controlled key properties such as the degree of graphitization, porosity, chemical composition, and electrochemical performance. The optimized activated carbon exhibited a high specific surface area of 1055 m2 g- 1 and delivered a reversible specific capacity of 393 mAh g- 1 after 650 charge/discharge cycles at a current density of 0.1 A g- 1. This superior electrochemical performance is attributed to the hierarchical porous structure and heteroatom doping, which synergistically enhance lithium-ion diffusion and electron transport. These findings not only underscore the potential of JUJUNCAO as a sustainable, high-performance anode material for LIBs but also pave the way for the high-value utilization of biomass in green energy storage technologies.

Abstract&Keyword Cite

Abstract :

Tannin-based biomass foam was prepared through a self-foaming process at room temperature. The material's density, porosity, microstructure, mechanical properties, thermal stability, limiting oxygen index (LOI), brittleness, as well as water absorption and retention properties, were studied. Adding 2% bamboo fibers in varying forms did not affect the uniformity of the foam cells. The density, porosity, thermal stability, and LOI of the foam material remained largely unchanged. The compressive strength of the unmodified tannin foam was 0.043 MPa, while the addition of 2% bamboo fibers increased the compressive strength by 72%. Even when the effect of density was excluded, the specific compressive strength was enhanced by 60%. Additionally, brittleness, measured as the slagging percentage, was significantly reduced from 16.12% to 4.78%. The modified foam could absorb up to 26.5% of its weight in water, with excellent water retention capabilities of 78.1% after 120 h while retaining its structural integrity under intermittent wetting conditions, making it suitable for vertical greening applications. This demonstrates its suitability for vertical greening applications, where moisture exposure is frequent. In conclusion, the bamboo fiber-reinforced tannin-based foam exhibits excellent mechanical properties and superior water absorption and retention performance.
