采用总体能量平面波赝势方法,并结合超软赝势技术,计算了金属La、Ni及合金LaNi5的总体能量、能带结构、电子态密度以及Mulliken布居值。根据计算结果,分析了La 、Ni和LaNi5的电子结构。结果表明:形成合金后费米面能量位置漂移,介于Ni和La的费米面之间,费米面上主要是Ni3d电子;费米面附近导带的电子结构变化较大;合金中La和Ni间存在电子转移,形成了弱的La-Ni键,且带部分离子性;与纯金属相比,形成合金后La的稳定性增强,而Ni的稳定性减弱。计算了LaNi5的理论生成热,结果能较好地符合实验值。

【期刊论文】SnO2/石墨复合材料作为锂离子电池负极材料研究
吴锋, QI Zhi, WU Feng*
天机化学学报,21(2):257~261,-0001,():

Nano-scale SnO2 powders were prepared by hydrolyzation. Graphite was poured into the SnCl4 solution during hydrolyzation. After drying and calcining at 360℃, the negative electrode composite material of nanosized SnO2 and graphite was obtained. The composite materials were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The average erystallite size was in the range of 15-20nm. Electrochemical lithium insertion/extraetion was studied preliminarily on the obtained composite. The discharge capacity of nanosized SnO2/graphite composite was found to have a high electrochemical reversible capacity for Li-ion insertion and extraction, which possessed the advantages of both higher discharge capacity of SnO2 and lower discharge potential of graphite. In addition, the cycle capability was also improved due to the inhibiting effect of the composite against pulverization and agglomeration to a certain extent during Li-ion insertion and extraction.

The new room-temperaturemolten saltwas prepared based on LiTFSI[LiNC (SO2CF3) 2] with OZO (C3H5NO2) which were not reported in literature. Its thermal and electrochemical properties were studied by differential scanning calorimetry, ac impedance spectroscopy and cyclic voltammertry respectively. The results indicated that the structure symmetry of the molecule was depressed and the extent of charges delocalization w as expanded, because of introducing oxygen atom of differential electronegativity in OZO molecule. DSC analysis show ed that the LiTFSI-OZO molten salt has the excellent thermal stability and its eutectic temperature is below about 223.15K. Meanw hile, the conductivity of LiTFSI-OZO molten salt at a molar ratio of 1∶4.5 is 0.75×10-3S/cm at 298.15 K and 3.50×10-3S/cm at 333115 K. CV analysis show ed that the electrochem icalw indow of the samp le is about 4V.

The effects of Co powder of different particle size and Co suboxide (Co1+x O,0≤x≤2), used as additives to the negative electrode, on 11x battery cycle life were investigated. The study shows that the addition of finer Co powder or Co1+xO has a significant effect on improving 11x the cycle life of the Ni-MH battery. In addition, the oxidation resistance of the MH negative electrode increases and the charging efficiency of the cell is enhanced.

The excellent over-potential with respect to the OER in strong basic solution of the SnO2-Sb2O3/Ti anode was applied to the investigation of the electrochemical behaviour of the redox couple FeO2 4 =FeO2. The results proved that ferrate could be generated by the electrochemical path without any side reaction of OER on the electrode of SnO2-Sb2O3/Ti. At the same time, the formation of Fe(Ⅲ) species, which formed a redox couple with FeO2 4 in strong basic solution, was confirmed as exclusively FeO2. The generation of FeO2 and the ionization of Fe(Ⅲ) hydroxide in very high concentration basic environment were explored and discussed. The results proved that acidity and acidic ionization of Fe(Ⅲ) hydroxide play an un-neglected role for the safe rechargeable superiron battery. Furthermore the mechanism of electrochemical generation of ferrate was investigated and exhibited as the mechanism of CEC. The relative barriers for the manufacture of secondary super-iron battery were discussed.

【期刊论文】Degradation analysis of nickel/metal hydride battery and its electrodes materials①

The results indicate that during charge and discharge, the expansion of Ni (OH) 2 crystal, pulverization of MH alloy particles and falling off from current collector are identified as the main causes for deterioration of Ni/MH batteries. Meanwhile, the contact resistance of inner battery increases due to the deterioration of the negative and positive electrode, and these changes lead to increasing battery body temperature and damaging its electrode and separator. The fibre's expansion and hole's diminishment of battery's separator after degradation will affect the electrochemical performance and cycle life of Ni/MH batteries.

Effects of iron phthalocyanine (FePc) on the inner pressure of MH/Ni batteries during charging were examined. Experimental results show that the battery with appropriate quantity of FePc displays a much lower inner pressure under charging and overcharging than the battery without FePc, especially the battery with 1mg FePc exhibits the slowest increasing speed of inner pressure and the best charging efficiency and overchargeability.

La2Mg17-based nanocrystalline alloys were prepared by ballmilling La2Mg17 alloy with Ni powders. Electrochemical charging and discharging of the ballmilled La2Mg17-based nanocrystalline alloy succeeded due to the formation of highly dispersed metallic Ni particles through the nanocrystalline alloy matrix. The first discharge capacity of the La2Mg17 alloys ballmilled with Ni powders in a weight ratio of 1:2 was near 990mAh/g, corresponding to a hydrogen storage capacity of 3.69 wt %. Inlaid metallic Ni at the surface layer of the nanocrystalline alloy matrix served as electrocatalytic reaction sites and hydrogen adsorption sites to accelerate the electrochemical charging and discharging process.
