    486-490页
    查看更多>>摘要：In order to advance the commercialization of rechargeable Li-air batteries,it is of importance to explore cathode catalyst with efficient catalytic activity.Transition metal oxides have poor electrical conductivity,while cobalt phosphide has excellent electrical conductivity and large specific surface area.Nevertheless,its application in organic Li-air batteries has been much less studied,and the electrocatalytic activity de-sires to be further elevated.Here,CoP/Co2P heterojunction composite with higher polarity was fabricated.The discharge product of high-polarity CoP/Co2P had a new porous box-like morphology,which was easy to be decomposed and exposed more active sites.The highly polar CoP/Co2P heterostructure composite had homogeneous pores,the synergistic effect existed between CoP and Co2P,and the discharge prod-uct was porous box mixed with Li2O2 and LiOH,which made CoP/Co2P achieve high specific capacity of 14632 mAh/g and cycle stably 161 times when used as air electrode cathode catalyst.This work furnished a thought for the construction of cathode catalysts with efficient catalytic activity for Li-air batteries.

    Manganese vanadium oxide composite as a cathode for high-performance aqueous zinc-ion batteries

    491-495页
    查看更多>>摘要：The development of clean renewable energy and energy storage devices is of great significance under the present energy crisis and environmental pollution background.Aqueous zinc-ion battery(ZIB)has become one of the most promising energy storage devices due to its high capacity,safety and low cost.However,the application of ZIB cathode is usually limited by low capacity and poor stability.Herein,we propose a novel heterostructure MnO/MnV2O4 composite material composed of MOF derivatives and spinel with dual active components as cathode for ZIBs.Benefited from substantial framework of MOF derivatives and the synergistic effect of heterostructures,MnO/MnV2O4 exhibits excellent rate performance(342 mAh/g at 0.1 A/g,261 mAh/g at 15 A/g)and cycling performance(198.9 mAh/g at 10 A/g after 2000 cycles)in 3mol/L Zn(CF3SO3)2 electrolytes.This work extends the range of developing high-performance cathodes for ZIBs under high current density and is expected to enlighten the optimization of commercial energy storage devices.

    Separator functionalization enables high-performance zinc anode via ion-migration regulation and interfacial engineering

    496-500页
    查看更多>>摘要：Aqueous zinc ion batteries(AZIBs)are promising energy storage devices.However,the formation of den-drites,hydrogen evolution,and corrosion reaction seriously affect their electrochemical performance.Herein,the synergistic effect of ion-migration regulation and interfacial engineering has been confirmed as the potential strategy by kaolin functionalized glass fiber separator(KL-GF)to alleviate these prob-lems.The rapid and orderly Zn2+migration was achieved to improve the transfer kinetics and induced uniform zinc deposition by more zinc-philic sites of KL-GF.Based on the interfacial engineering,the side reactions were effectively mitigated and crystal planes were regulated through KL-GF.The hydrophilicity of KL alleviated the corrosion and hydrogen evolution.Importantly,a preferential orientation of Zn(002)crystal plane by KL-GF was induced to further realize dendrite-free deposition by density functional the-ory(DFT)and X-ray diffraction(XRD)characterization.Hence,the Zn|KL-GF|MnO2 cell maintained a high discharge capacity of 96.8 mAh/g at 2 A/g after 1000 cycles.This work can provide guidance enabling high-performance zinc anode for AZIBs.

    "Co-coordination force"assisted rigid-flexible coupling crystalline polymer for high-performance aqueous zinc-organic batteries

    Jun GuoZhenbang ZhuangWanqiang LiuGang Huang...
    501-506页
    查看更多>>摘要：Organic electrode materials(OEMs)have attracted substantial attention for aqueous zinc-ion batteries(AZIBs)due to their advantages in relieving resource and environmental anxiety.However,the poten-tial of OEMs is plagued by their low achievable capacity and high solubility.Here,we have proposed a new concept of"co-coordination force"and designed a rigid-flexible coupling crystalline polymer that can overcome the abovementioned limitations.The obtained crystalline polymer(BQSPNs)with multire-dox centres makes the BQSPNs exist intermolecular hydrogen bonds(HB)among-C=O,-C=N,and-NH and consequently exhibits transverse two-dimensional arrays and longitudinal π-π stacking structure.Additionally,in-situ FTIR,Raman,variable temperature FTIR spectra,and 2D nuclear overhauser effect spectroscopy(NOESY)well capture the existence and evolution process of HB during the electrochem-istry reaction process of BQSPNs,uncovering the effect of HB in stabilizing the structure and promoting the reaction kinetics.As a result,the BQSPNs with rationally designed"co-coordination force"deliver a high capacity of 459.6 mAh/g and a stable cycling lifetime for more than 100,000 cycles at 10 A/g in AZIBs.Our results disclose the HB effect and provide a brand-new strategy for high-performance OEMs design.

    A water-stable high-voltage P3-type cathode for sodium-ion batteries

    Shengyu ZhaoXuan YuYufeng Zhao
    507-513页
    查看更多>>摘要：The Na-deficient P3-type layered oxide cathode material usually experience complex in-plane Na+/vacancy ordering rearrangement and undesirable P3-03 phase transitions in the high-voltage region,leading to inferior cycling performance.Additionally,they exhibit unsatisfactory stability when exposed to water for extended periods.To address these challenges,we propose a Cu/Ti co-doped P3-type cath-ode material(Na0.67Ni0.3Cu0.03Mn0.6Ti0.07O2),which effectively mitigates Na+/vacancy ordering and sup-presses P3-O3 phase transitions at high voltages.As a result,the as-prepared sample exhibited outstand-ing cyclic performance,with 81.9％retention after 500 cycles within 2.5-4.15 V,and 75.7％retention after 300 cycles within 2.5-4.25 V.Meanwhile,it demonstrates enhanced Na+transport kinetics during desodi-ation/sodiation and reduced growth of charge transfer impedance(Rct)after various cycles.Furthermore,the sample showed superb stability against water,exhibiting no discernible degradation in structure,mor-phology,or electrochemical performance.This co-doping strategy provides new insights for innovative and prospective cathode materials.

    Interface engineering of 2D NiFe LDH/NiFeS heterostructure for highly efficient 5-hydroxymethylfurfural electrooxidation

    Lili WangYa YanRulin LiXujie Han...
    514-520页
    查看更多>>摘要：The electrochemical oxidation of 5-hydroxymethylfurfural(HMF)to valuable chemicals is an efficient way to upgrade biomass molecules and replace traditional catalytic synthesis.It is crucial to develop effi-cient and low-cost earth-abundant electrocatalysts to enhance catalytic performance of HMF oxidation.Herein,a new type of two-dimensional(2D)hybrid arrays consisting of NiFe layered double hydroxides(LDH)nanosheets and bimetallic sulfide(NiFeS)is constructed via interface engineering for efficient elec-trocatalytic oxidation of HMF to 2,5-furandicarboxylic acid(FDCA).The preparation process of 2D NiFe LDH/NiFeS with ultrathin heterostructure involves in anchoring a Co-based metal-organic framework(Co MOF)as template onto the carbon cloth(CC)via in-situ growth,formation of NiFe LDH on the surface of Co MOF and subsequent partial sulfidation.The electrocatalyst of NiFe LDH/NiFeS exhibits outstanding performance towards HMF oxidation,about 98.5％yield for FDCA and 97.2％Faraday efficiency(FE)in the alkaline electrolyte with 10mmol/L HMF,as well as excellent stability retaining 90.1％FE for FDCA after six cycles test.Moreover,even at an HMF concentration of 100mmol/L,the yield and FE for FDCA remain high at 83.6％and 93.6％,respectively.These findings highlight that 2D heterostructure containing abun-dant interfaces between NiFe LDH nanosheets and NiFeS can enhance the intrinsic activity of LDH and thus promote the oxidation reaction kinetics.Additionally,the synergistic effect of the bimetallic NiFe compounds also improved the selectivity of HMF conversion to FDCA.Our present work demonstrates that constructing 2D ultrathin heterostructure of NiFe LDH/NiFeS is a facile strategy via interface engi-neering to enhance the intrinsic activity of LDH electrocatalysts,which would open new avenues toward low-cost and advanced 2D nanocatalysts for sustainable energy conversion and electrochemical valoriza-tion of biomass derivatives.
