With the merits of the high energy density of batteries and power density of supercapacitors,the aqueous Zn-ion hybrid supercapacitors emerge as a promising candidate for applications where both rapid energy delivery and moderate energy storage are required.However,the narrow electrochemical window of aqueous electrolytes induces severe side reactions on the Zn metal anode and shortens its lifespan.It also limits the operation voltage and energy density of the Zn-ion hybrid supercapacitors.Using'water in salt'electrolytes can effectively broaden their electrochemical windows,but this is at the expense of high cost,low ionic conductivity,and narrow temperature compatibility,compromising the electrochemical performance of the Zn-ion hybrid supercapacitors.Thus,designing a new electrolyte to balance these factors towards high-performance Zn-ion hybrid supercapacitors is urgent and necessary.We developed a dilute water/acetonitrile electrolyte(0.5 m Zn(CF_(3)SO_(3))_(2)+1 m LiTFSI-H_(2)O/AN)for Zn-ion hybrid supercapacitors,which simultaneously exhibited expanded electrochemical window,decent ionic conductivity,and broad temperature compatibility.In this electrolyte,the hydration shells and hydrogen bonds are significantly modulated by the acetonitrile and TFSI-anions.As a result,a Zn-ion hybrid supercapacitor with such an electrolyte demonstrates a high operating voltage up to 2.2 V and long lifespan beyond 120,000 cycles.

The development of a high specific capacity and stable manganese(Mn)-based cathode material is very attractive for aqueous zinc-ion(Zn^(2+))batteries(ZIBs).However,the inherent low electrical conductivity and volume expansion challenges limit its stability improvement.Here,a mesoporous ZnMn_(2)O_(4)(ZMO)nanocage(N-ZMO)coupled with nitrogen doping and oxygen vacancies is prepared by defect engineering and rational structural design as a high-performance cathode material for rechargeable ZIBs.The oxygen vacancies enhance the electrical conductivity of the material and the nitrogen doping releases the strong electrostatic force of the material to maintain a higher structural stability.Interestingly,N-ZMO exhibits excellent ability of Zn^(2+)storage(225.4 mAh·g^(−1)at 0.3 A·g^(−1)),good rate,and stable cycling performance(88.4 mAh·g^(−1)after 1,000 cycles at 3 A·g^(−1)).Furthermore,a flexible quasi-solid-state device with high energy density(261.6 Wh·kg^(−1))is assembled,demonstrating long-lasting durability.We believe that the strategy in this study can provide a new approach for developing aqueous ZIBs.

High-performance energy storage and sensing devices have been undergoing rapid development to meet the demand for portable and wearable electronic products,which require flexibility,extensibility,small volume and lightweight.In this study,we construct a lightweight and flexible self-powered sensing system by integrating a highly stretchable strain sensor with a high-performance asymmetric supercapacitor based on ZnSe/CoSe_(2)//ECNT(ECNT:electrochemically activated carbon nanotube film).The ZnSe/CoSe_(2) two-dimentional nanosheets on carbon nanotube(CNT)films are synthesized through a simple and efficient strategy derived from ZnCo-based metal-organic frameworks(MOFs).The density functional theory(DFT)simulations show the higher conductivity of the ZnSe/CoSe_(2)/CNT electrode than the CoSe_(2)/CNT electrode.Due to the synergistic properties of self-supported two-dimentional ZnSe/CoSe_(2) nanosheets with high specific surface area and the high pathway of one-dimention CNTs,the nanocomposite electrode provides efficient transmission and short paths for electron/ion diffusion.The asymmetric supercapacitor provides a stable output power supply to the sensors that can precisely respond to strain and pressure changes.The sensor can also be attached to a garment for measuring a variety of joint movements.

Novel cobalt Fischer-Tropsch synthesis （FTS） catalysts were prepared from natural halloysite nanotubes （HNT） by double-solvent and wet- impregnation methods, and characterized by TEM, XRD, TPR and N2 adsorption-desorption. Comparing with the catalyst prepared by wet- impregnation method, the catalyst prepared by double-solvent method reduces Co3O4 particle migration and agglomeration due to size-induced effect, thus showing higher catalytic activity for Fischer-Tropsch synthesis.

Enhancing the long-term Na-storage cyclability of conversion-type iron selenide composite by construction of 3D inherited hyperbranched polymer buffering matrix

Nano Research 2021年第11期14卷 3952-3960页

作者： Hao Li Changchun Hu Yaping Xia Ting Li daohong zhang Fei Xu Key Laboratory of Catalysis and Energy Materials Chemistry of Ministry of Education&Hubei Key Laboratory of Catalysis and Materials Science Hubei R&D Center of Hyperbranched Polymers Synthesis and ApplicationsSchool of Chemistry and Materials ScienceSouth-Central University for NationalitiesWuhan430074China Key Laboratory of Hydraulic Machinery Transients Ministry of EducationSchool of Power and Mechanical EngineeringWuhan UniversityWuhan430072China

Electrochemical conversion reactions provide more selections for Na-storage materials, but the reaction suffers from low reversibility and poor cyclability. Introducing an electrochemically inactive component is a common strategy, but the effect is quite limited since it could not stabilize the structure during long-term cycling. In this study, a new approach is developed using an amino group-functioned hyperbranched polymer (AHP) as a template and electrode additive for the design of high-performance FeSe2-AHP composite with chemical interaction. The assembled FeSe2-AHP composite nanoneedles were prepared by the selenylation of FeS-AHP composite microflowers and entirely inherit the polymer network from the precursor. The amino groups of AHP in composite coordinate with iron cations to achieve uniform polymer dispersion in the composite, and maintain the molecular level mixed state during the long-term cycling. Moreover, the in-situ constructed uniform 3D elastic polymer network effectively accommodates volume expansion and alleviates nanoparticle aggregation during sodiation/de-sodiation. FeSe2-AHP composite provides a superior rate capability (584.8 mAh·g−1 at 20 A·g−1) and a remarkable cyclability with a capacity retention rate of 93.3% after 2,000 cycles. FeSe2-AHP composite shows a high pseudocapacitive behavior for the abundant nanometer interface established by AHP, enhancing the solid-state Na+ diffusion. The FeSe2-AHP anode is also compatible with Na3V2(PO4)3/C cathode in a full Na-ion battery, which provides a high-power performance (powering 51 LEDs). The work herein highlights an innovative and efficient strategy for conversion-type material design and demonstrates the function of chemical interaction of polymer additive in the enhancement of long-term cyclability for conversion electrode.

The study on toughening and reinforcing of bisphenol-A epoxy resin is one of important developmental direction in the field.This paper reports a one-pot synthesis of aromatic polyester hyperbranched epoxy resin HTDE-2,an effect of HTDE-2 content on the mechanical and thermal performance of the bisphenol-A(E51)/HTDE-2 hybrid resin in detail.Fourier transform infrared(FT-IR)spectrometer,scanning electronic microscopy(SEM),differential scanning calo ri metry(DSC),thermogravimetric analysis(TGA),dynamic mechanical thermal analysis(DMA)and molecular simula tion technology are used to study the structure of HTDE-2,performance and toughening and reinforcing mech-anism of the HTDE-2/E51 hybrid resin.It has been shown that the content of HTDE-2 has an important effect on the performance of the hybrid resin,and the performance of the HTDE-2/E51 blends has maximum with the increase in HTDE-2 content.The impact strength and fracture toughness of the hybrid resin with 9 wt-%HTDE-2 are almost 3.088 and 1.749 times of E51 performance respectively,furthermore,the tensile and flexural strength can also be enhanced about 20.7% and 14.2%,respectively.The glass transition tem-perature and thermal degradation temperature,however,are found to decrease to some extent.
