4Recent developments of aprotic lithium-oxygen batteries: functional materials determine the electrochemical performance显示文摘Lithium oxygen battery has the highest theoretical capacity among the rechargeable batteries and it can reform energy storage technology if it comes to commercialization. However,many critical challenges,mainly embody as low charge/discharge round-trip efficiency and poor cycling stability,impede the development of Li-O_2 batteries. The electrolyte decomposition,lithium metal anode corrosion and sluggish oxygen reaction kinetics at cathode are all responsible for poor electrochemical performances.Particularly,the catalytic cathode of Li-O_2 batteries,playing a crucial role to reduce the oxygen during discharging and to decompose discharge products during charging,is regarded as a breakthrough point that has been comprehensive investigated. In this review,the progress and issues of electrolyte,anode and cathode,especially the catalysts used at cathode,are systematically summarized and discussed.Then the perspectives toward the developments of a long life Li-O_2 battery are also presented at last.Xin Guo Bing Sun Dawei Su Xiaoxue Liu Hao Liu Yong Wang Guoxiu Wang 2017Science Bulletin2017,62,6:8
5Controlled fabrication and electrical-magnetic properties of Poly(OT-co-AN)/Ba_(0.8)La_(0.2)Al_2Fe_(10)O_(19) composites显示文摘Poly(OT-co-AN)/Ba0.8La0.2Al2Fe10O19(Poly(OT-co-AN)/BLAF) composites were fabricated by in situ polymerization method.It was investigated that of mass rate of momomer(mOT/mAN),polymeration temperature and time,and feeding ratio of BLAF effect on the structures,morphology,conductivity,magnetic property of composites by the orthogonal optimum design.The results indicated that poly(OT-co-AN) copolymer had a better coating on BLAF particles,and there were some interactions between components in the composites.The magnetic properties of the composites were related to content of the magnetic BLAF particles in it.The feeding ratio of BLAF had a significant influence on constitute and conductivity of the composites,followed by the temperature.The reflection loss and the effective bandwidth of composites for electromagnetic wave were at-tributed to the synergistic effect between poly(OT-co-AN) and BLAF.The poly(OT-co-AN)/BLAF composites with mass ratio of BLAF to mix monomer(mOT/mAN =1:1) equal to 5/1 at 10 h in 25°C had a maximum synergistic effect between its compo-nents,showed a maximum reflection loss of ?26.94 dB at 14.10 GHz and an available bandwidth of 8.54 GHz.It was sug-gested that the composites can be used as a advancing absorption and shielding materials for electromagnetic wave due to their favorable microwave absorption properties.CHEN KeYu XU QingQing LI LiangChao TONG GuoXiu QIAN HaiSheng XIAO QiuShi XU Feng 2012Science China(Technological Sciences)2012,55,1:4
6Effects of Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum on chemotactic migration of alveolar macrophages and inters regions macrophages in rats显示文摘OBJECTIVE: To observe the effects of serum containing Mahuang(Herba Ephedra Sinica) or Wuweizi(Fructus Schisandrae Chinensis) on the migration of alveolar macrophages(AM) and interstitial macrophages(IM) from normal rats, and to analyze and compare the mechanisms leading to cell migration differences.METHODS: Rats were randomly divided into three groups: Mahuang(Herba Ephedra Sinica), Wuweizi(Fructus Schisandrae Chinensis), and blank serum. After treatment with the herbs, serum was extracted from the rats. AM and IM were isolated from normal rats and cultured. The effects of Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum on normal rat AM and IM chemotactic migration were determined by transwell assays. The CC chemokine receptor(CCR) 2, CCR5, voltage-gated Kvl. 3 K^+channel(Kv1. 3), and voltage-gated Kvl. 5 K^+channel(Kv1. 5) protein levels were analyzed by western blotting.RESULTS: The migration quantities of AM and IM in the Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum groups were significantly higher than those in the blank serum group(P < 0.01). Compared with the Wuweizi(Fructus Schisandrae Chinensis) medicated serum group, the migration quantity of cultured rat AM in the Mahuang(Herba Ephedra Sinica) medicated serum group was significantly increased(P <0.01). Meanwhile, compared with the Mahuang(Herba Ephedra Sinica) medicated serum group, the migration quantity of cultured rat IM in the Wuweizi(Fructus Schisandrae Chinensis) medicated serum group was significantly increased(P < 0.01).CCR2, CCR5, Kv1. 3, and Kv1. 5 proteins were expressed on the AM cell surface, and showed significantly higher expression in the Mahuang(Herba Ephedra Sinica) medicated serum group compared with the Wuweizi(Fructus Schisandrae Chinensis)medicated serum group. In contrast, CCR5, Kv1.3,and Kv1.5 proteins were expressed on the IM cell surface, and showed significantly higher expression in the Wuweizi(Fructus Schisandrae Chinensis)medicated serum group compared with the Mahuang(Herba Ephedra Sinica) medicated serum group.CONCLUSION: Mahuang(Herba Ephedra Sinica)and Wuweizi(Fructus Schisandrae Chinensis) can promote AM and IM migration ability, with Mahuang(Herba Ephedra Sinica) targeting AM more apparently and Wuweizi(Fructus Schisandrae Chinensis) targeting IM more apparently. The mechanism may be that, by stimulating cells, Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) promote expression of CCR2 and CCR5 receptors on the AM and IM cell surface,which pass signals to Kvl.3 and Kvl.5 ion channels,leading to changes in the cytoskeleton, and ultimately promoting chemotactic cell migration.Yuan Yiping Zhai Huaqiang Zhang Tian Guo Zhaojuan Kong Liting Jia Xiaoyu Wang Ningning Dai Ying Liu Guoxiu Wang Yanping 2017Journal of Traditional Chinese Medicine2017,37,5:3
7High valence metals engineering strategies of Fe/Co/Ni-based catalysts for boosted OER electrocatalysis显示文摘Electrocatalysis for the oxygen evolution reactions(OER)has attracted much attention due to its important role in water splitting and rechargeable metal-air batteries.Therefore,designing highly efficient and low-cost catalysts for OER process is essential as the conventional catalysts still rely on precious metals.Transition metal-based compounds have been widely investigated as active OER catalysts,and renewed interest in the high valence metals engineered compounds has been achieved for superior catalytic activity and stability.However,an in-depth understanding of the construction strategies and induced effects for the high valence metals engineered catalysts is still lacking and desired.In this review,we have summarized the construction strategies of high valence metals as dopants or formed heterostructures with the iron/cobalt/nickel(Fe/Co/Ni)-based catalysts.Then the induced effects on Fe/Co/Ni-based catalysts by incorporating high valence metals,e.g.,accelerating the surface reconstruction,forming amorphous structure,generating vacancies/defects,and acting as stabilizers,are highlighted.The impacts of high valence metals on OER performance are elucidated based on different elements,including molybdenum(Mo),tungsten(W),cerium(Ce),vanadium(V),chromium(Cr),manganese(Mn),niobium(Nb),zirconium(Zr).The correlations of construction strategies,induced effects,catalytic activity and OER reaction pathways are elaborated.Finally,the remaining challenges for further enhancements of OER performance induced by high valence metals are presented.Lu Li Xianjun Cao Juanjuan Huo Junpeng Qu Weihua Chen Chuntai Liu Yufei Zhao Hao Liu Guoxiu Wang 2023Journal of Energy Chemistry2023,,1:3
8Effect of liquid-solid ratio on the morphology,structure,conductivity,and electromagnetic characteristics of iron particles显示文摘Using a ball-milling technique,polymorphous iron particles were prepared by changing only the liquid-solid ratioλ.Effects of λon their morphology,structure,conductivity,and electromagnetic properties were studied.The results show that an increase ofλfrom 0 to 0.25 causes a nonlinear decrease of the conductivity in the ranges of 88.50-2.25 S cm-1 and a regular variation of the electromagnetic parameters,corresponding to the as-obtained iron particles.This is ascribed to a combination of the increased shape anisotropy and the decreased fresh surface with active atoms deriving from the weakened welding-on action and the enhanced micro-malleation action in the ball-milling process.Hereinto,the iron flakes formed at wet-milling with λ=0.08-0.25 have lower conductivity,higher permittivity and permeability,and more excellent absorption property compared with the irregular iron particles obtained at dry-milling withλ=0.It is a consequence of the synergistic effect of dielectric relaxation loss,exchange energy and conductance loss originating from the flake-shape structures.This indicates that the morphology,structure,conductivity,and electromagnetic properties of the products can be effectively controlled by changingλ.TONG GuoXiu HUA Qiao WU WenHua QIN MingYue LI LiangChao GONG PeiJun 2011Science China(Technological Sciences)2011,54,2:2
9A functional hyperbranched binder enabling ultra-stable sulfur cathode for high-performance lithium-sulfur battery显示文摘Binders are of vital importance in stabilizing the cathodes to enhance the cycling stability of lithiumsulfur(Li-S) batteries. However, conventional binders are typically confronted with the drawback of inability for adsorbing lithium polysulfide(Li PS), thus resulting in severe active material losing and rapid capacity fading. Herein, a novel water-soluble hyperbranched poly(amidoamine)(HPAA) binder with controllable hyperbranched molecular structure and abundant amino end groups for Li-S battery is designed and fabricated, which can improve efficient adsorption for Li PS and stability of the sulfur cathodes. Besides, the strong intermolecular hydrogen bonds in HPAA binder can contribute to the structural stability of S cathode and integration of the conductive paths. Therefore, the Li-S battery with this functional binder exhibits excellent cycle performance with a capacity retention of 91% after 200 cycles at 0.1 C.Even at a high sulfur loading of 5.3 mg cm-2, a specific capacity of 601 mA h g-1 can also be achieved.Density functional theory(DFT) calculation further demonstrates that the enhanced electrochemical stability derives from the high binding energy between amino groups and LiP S and the wide electrochemical window(6.87 e V) of HPAA molecule. Based on the above all, this functional polymer will lighten a new species of binders for eco-friendly sulfur cathodes and significantly promote the practical applications of high-performance Li-S batteries.Xiang Luo Xianbo Lu Xiaodong Chen Ya Chen Chunyang Yu Dawei Su Guoxiu Wang Lifeng Cui 2020Journal of Energy Chemistry2020,29,11:2
10Metal-organic-framework-derived formation of Co–N-doped carbon materials for efficient oxygen reduction reaction显示文摘Non-precious metal nitrogen-doped carbonaceous materials have attracted tremendous attention in the field of electrochemical energy storage and conversion.Herein,we report the designed synthesis of a novel series of Co-N-C nanocomposites and their evaluation of electrochemical properties.Novel yolkshell structured Co nanoparticles@polymer materials are fabricated from the facile coating polymer strategy on the surface of ZIF-67.After calcination in nitrogen atmosphere,the Co–N–C nanocomposites in which cobalt metal nanoparticles are embedded in the highly porous and graphitic carbon matrix are successfully achieved.The cobalt nanoparticles containing cobalt metal crystallites with an oxidized shell and/or smaller(or amorphous)cobalt-oxide deposits appear on the surface of graphitic carbons.The prepared Co–N–C nanoparticles showed favorable electrocatalytic activity for oxygen reduction reactions,which is attributed to its high graphitic degree,large surface area and the large amount existence of Co–N active sites.Hao Tian Chi Zhang Panpan Su Zhangfeng Shen Hao Liu Guoxiu Wang Shaomin Liu Jian Liu 2020Journal of Energy Chemistry2020,29,1:2
11Towards High-Energy and Anti-Self-Discharge Zn-Ion Hybrid Supercapacitors with New Understanding of the Electrochemistry显示文摘Aqueous Zn-ion hybrid supercapacitors(ZHSs)are increasingly being studied as a novel electrochemical energy storage system with prominent electrochemical performance,high safety and low cost.Herein,high-energy and anti-self-discharge ZHSs are realized based on the fibrous carbon cathodes with hierarchically porous surface and O/N heteroatom functional groups.Hierarchically porous surface of the fabricated free-standing fibrous carbon cathodes not only provides abundant active sites for divalent ion storage,but also optimizes ion transport kinetics.Consequently,the cathodes show a high gravimetric capacity of 156 mAh g^(−1),superior rate capability(79 mAh g^(−1)with a very short charge/discharge time of 14 s)and exceptional cycling stability.Meanwhile,hierarchical pore structure and suitable surface functional groups of the cathodes endow ZHSs with a high energy density of 127 Wh kg−1,a high power density of 15.3 kW kg^(−1)and good anti-self-discharge performance.Mechanism investigation reveals that ZHS electrochemistry involves cation adsorption/desorption and Zn_(4)SO_(4)(OH)_(6)·5H_(2)O formation/dissolution at low voltage and anion adsorption/desorption at high voltage on carbon cathodes.The roles of these reactions in energy storage of ZHSs are elucidated.This work not only paves a way for high-performance cathode materials of ZHSs,but also provides a deeper understanding of ZHS electrochemistry.Yang Li Wang Yang Wu Yang Ziqi Wang Jianhua Rong Guoxiu Wang Chengjun Xu Feiyu Kang Liubing Dong 2021Nano-Micro Letters2021,13,6:2
