The monoclinic CuNb2O6(M-CNO)with a columbite structure is a potential anode candidate for advanced lithium-ion capacitors(LICs).However,its practical application is plagued seriously by the irreversible phase transformation and sluggish kinetics.For this,herein,we develop an adjustable Cu-site Ni substituting strategy to regulate the phase transition(i.e.,NixCu1-xNb2O6)from M-CNO to orthorhombic NiNb2O6.With the fine optimization in Ni substitution,the stresshermal-induced phase transformation and the initial electrochemical conversion are effectively prevented in the optimal Ni0.5Cu0.5Nb2O6(55NCNO).Moreover,elaborate experimental observation and theoretical calculations synergistically authenticate that the orthorhombic 55NCNO phase is endowed intrinsically with both superb Li+and electronic conductivities,thanks to its large two-dimensional Li+diffusion channel and narrow band gap.Benefiting from such appealing merits,55NCNO with the solid-solution Li+-storage mechanism obtains attractive high-rate capacities and cycling stability,when evaluated as a competitive anode for LICs.Besides,the 55NCNO constructed LICs display a striking energy density of 49.5 Wh kg-1 at 10.8 kW kg-1 along with long-span cycle life(just 0.0065% capacitance decay per cycle).More significantly,the heteroatomic substitution methodology here will guide future design of advanced anodes for next-generation LICs,and propel their practical advancement. 展开更多

Metal-organic framework materials exhibit considerable potential as molecularly selective surfaceenhanced Raman spectroscopy(SERS)substrates because of their microporous structures,which enrich small molecules while excluding larger ones.In this study,we develop a template-assisted chemical-etching strategy to prepare layered tuneable SERS substrates based on hierarchical porous zeolitic imidazolate framework-67(HP-ZIF-67)with a rhombic dodecahedral structure.The synergistic SERS enhancement mechanisms of HP-ZIF-67,which combine electromagnetic(EM)and chemical(CM)effects,were systematically studied through numerical simulations and experiments.Calculations revealed that under 633-nm laser excitation,the contributions of the EM and CM effects to the total SERS enhancement factor of HP-ZIF-67 were 60%and 40%,respectively.The hierarchical porous structure enhanced the fluid-flow flux over the microporous ZIF-67 because the increased pore radius reduced the viscous resistance and facilitated rapid molecular transport through the interconnected macro-meso-channels.Precise modulation of the CM and EM effects,combined with enhanced mass transfer,facilitated the development of HP-ZIF-67and HP-ZIF-67@Au as efficient SERS sensors.An investigation of the relationship between pore-size distribution and EM effects revealed the pivotal role of light confinement by whispering-gallery-mode microcavities in enhancing the SERS performance.The optimised HPZIF-67@Au composites functioned as flexible and highly sensitive in situ SERS sensors for gases and liquids,including volatile organic-compound gas and liquid-pesticide residues.This study introduces a novel design concept and provides a robust theoretical foundation for the future development of exhaled-breath point-of-care diagnostic devices and sweat-based wearable biomedical sensors. 展开更多

Recently,CoCO3has attracted enormous attention as anodes for lithium-ion batteries(LIBs),benefiting from its high theoretical capacity and simple synthesis.However,the modest electronic conductivity and structural instability over cycling hinder its wider applications.To well address the intrinsic issues,we explored a precipitantfree hydrothermal methodology for mass production of spindle-like CoCO3educed graphene oxide(S-CoCO3GO)toward advanced LIBs as a hybrid anode.The dimethylformamide plays a significant role of"two birds(i.e.,solvent and precipitant)with one stone"in the formation of the S-CoCO3GO,greatly improving its practical applicability.The purposeful introduction of rGO nanosheets as a two-dimensional flexible conductive network enhances the conductivity and stability of the S-CoCO3.It is the structural and compositional merits for LIBs that endow the S-CoCO3GO with remarkable lithium-storage performance in terms of enhanced interfacial storage capacity,high-rate reversible capacities(803 mAh·g-1at 2.0 A·g-1)and long-duration capacity retention of 82.1%over 2000 consecutive cycles at 2.0 A·g-1.More significantly,the simple yet efficient avenue here promises enormous commercial prospect of the S-CoCO3GO in next-generation LIBs. 展开更多

The shuttling diffusion of polysulfides is a bottleneck that seriously limits the performance of Li-S batteries.Purposeful construction of sulfur cathodes with reliable trapping ability of polysulfides is the key to overcome such limitation.Herein,a hierarchical porous architecture,i.e.,Co(OH)2sheets bonded Ti_3C2T_x MXene aerogel(Co(OH)2/MXA),is constructed via a facile selfassembled approach and used as an efficient free-standing polysulfides reservoir.The interconnected three-dimensional(3D)porous network with void space and strong interfacial interaction not only enables high sulfur loading but facilitates fast ion and electron transport.Experimental and theoretical results confirm the hetero-framework exhibits outstanding immobilization and conversion ability for polysulfides due to its polar surface and bifunctional catalytic activities toward both formation and decomposition of Li2S.The optimized Co(OH)2/MXA cathode delivers excellent rate capability(407 mAh·g-1at 5C)with a sulfur loading of 2.7 mg·cm-2,and ultra-stable cycling performance as an extremely small capacity decay of~0.005%per cycle within 1700 cycles at 1C is achieved with a high sulfur loading of 6.7 mg·cm-2.More significantly,our design structural/componential methodology here promises the MXene-based aerogel electrodes for LiS batteries and beyond. 展开更多

Potassium ion hybrid capacitors(PIHC)have promising applications in medium and large-scale energy storage systems due to their high energy/power density,abundant potassium resource and low cost.However,the slow kinetics of battery-type anodes originating from the large-size K+results in a mismatch between the two electrodes,rendering the modest energy density of PIHC.Herein,we first develop an electrospinning strategy to successfully synthesize fibrous precursor by using the HNO3pre-oxidized low-softening-point coal pitch as the low-cost raw material.With further carbonization or KOH activation,the two types of carbon nanofibers(CNF)are fabricated as anode and cathode materials,respectively,towards the dual-carbon PIHC devices.Thanks to its threedimensional interconnected porous conducting network and large layer spacing,the resulted CNF anode material is endowed with high reversible capacities,excellent rate and long cycle stability.Meanwhile,the activated CNF cathode with a large surface area of 2169 m2·g-1exhibits excellent capacitive performance.A PIHC constructed with the two fibrous electrodes delivers an energy density of110.0 Wh·kg-1at 200.0 W kg-1,along with a capacitance retention of 83.5%after 10,000 cycles at 1.0 A·g-1.The contribution here provides a cost-efficiency avenue and platform for advanced dual-carbon PIHC. 展开更多
