| 1 | Influence of Cr^(3+) concentration on the electrochemical behavior of the anolyte for vanadium redox flow batteries显示文摘The composition of electrolyte affects to a great extent the electrochemical performance of vanadium redox flow batteries(VRB).The effects of Cr3+ concentration in the anolyte on the electrode process of V(V)/V(IV) couple have been investigated by cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS).It was found that Cr3+ causes no side reactions,but affects the electrochemical performance of V(V)/V(IV) redox reaction,including the reaction activity,the reversibility of electrode reaction,the diffusivity of vanadium ions,the interface film impedance,and the electrode reaction impedance.The experimental results show that Cr3+ within a certain concentration range can improve the reversibility of electrode reaction and the diffusion of vanadium ions.With the Cr3+ concentration increasing from 0 to 0.30 g L-1,the reversibility of V(V)/V(IV) reaction increases,while the diffusion resistance decreases.Correspondingly,the diffusion coefficient of vanadium ions increases from(5.48-6.77) × 10-7 to(6.82-8.44) × 10-7 cm2 s-1,an increase of ~24%.However,the diffusion resistance increases and the diffusion coefficient decreases when Cr3+ concentration is over 0.30 g L-1,while the impedances of the interface,the film as well as the charge transfer increase continuously.As a result,Cr3+ with a certain concentration improves the diffusion and mass transfer process,but the resistances of the film,the interface,and the charge transfer rise.Furthermore,Cr3+ concentration of no more than 0.10 g L-1 has few effect on the electrode reaction process,and that of no more than 0.30 g L-1 is favorable to the diffusion of vanadium ions. | HUANG Fei ZHAO Qiang LUO ChunHui WANG GuiXin YAN KangPing LUO DongMei | 2012 | Chinese Science Bulletin2012，57，32： | 4 |

| 3 | Mass production of Li Fe PO_4/C energy materials using Fe–P waste slag显示文摘To effectively solve the agglomeration problems in the solid state reaction process,pre-adding glucose is adopted to the synthesis of Li Fe PO4/C energy materials using Fe–P waste slag. The average particle & grain size of Li FeP O4/C decreases,and the impurities in Li Fe PO4/C composites reduce to a great extent. It makes great sense to the mass industrial production. The optimum synthesis conditions determined in this work are based on the orthogonal experiments. The samples synthesized in a scale of 500 g exhibit high purity,excellent electrochemical performance,high reaction activity,good reversibility,and low polarization level.The discharge capacities are 145,134,117,and 102 m Ah/g at the current densities of 0.1 C,0.2 C,0.5 C and1 C,respectively. This work puts forward a practical suggestion for mass producing environmental benign and low cost Li FeP O4/C as cathode materials of lithium ion batteries. | Gen Li Pengcheng Wu Chunhui Luo Qian Cui Guixin Wang Kangping Yan | 2015 | Journal of Energy Chemistry2015，24，4： | 2 |
| 4 | Growth Mechanism of Different Morphologies of ZnO Crystals Prepared by Hydrothermal Method显示文摘Different morphologies of zinc oxide(ZnO),including microrods,hexagonal pyramid-like rods and flower-like rod aggregates,had been synthesized,respectively,on glass substrates by controlling the reaction conditions(such as precursor concentration,reaction time and pH value) of hydrothermal method.The morphologies of the as-obtained ZnO were observed with scanning electron microscopy and transmission electron microscopy.Also,the crystalline natures of different ZnO crystals were analyzed with X-ray diffraction.The possible growth mechanism of ZnO crystals with different morphologies was discussed. | Hu Wang Juan Xie Kangping Yan Ming Duan | 2011 | Journal of Materials Science & Technology2011，27，2： | 1 |
