The samples were investigated by granularity analysis, scanning electron microscopy and X-ray diffraction. Results showed that sample synthesized by sol-gel procedure had a relatively smaller particle size compared with the products prepared by solid-state reaction, and had an ample surface. Electrochemical properties were investigated by charge/discharge cycle at 0.1 C rate with lithium as the anode. A high discharge specific capacity 122.42 mAh·g-1 was reached at the first cycle, with hardly capacity fading after 20 cycles.展开更多

The as-sintered samples were investigated by X-ray diffraction （XRD）, transmission electron microscopy （TEM）, N2 adsorption-desorption and electrochemical measurement. It is found that Li3Vz（PO4）3 sintered at 700 ℃ possesses good wormhole-like mesoporous structure with the largest specific surface area of 188 cmZ/g, and the smallest pore size of 9.3 nm. Electrochemical test reveals that the initial discharge capacity of the 700 ℃ sintered sample is 155.9 mA.h/g at the rate of 0.2C, and the capacity retains 154 mA.h/g after 50 cycles, exhibiting a stable discharge capacity at room temperature.展开更多

文摘Li Po’s poems have been translated and disseminated internationally for hundreds of years.His poems about“jiu”have attracted many Western readers’attention after translation and introduction.Based on Li Po’s poems,this paper proves the fact that Li Po’s Jiu poems play an important role in the international communication of Chinese Jiu culture.With Chinese culture’s“going out”,translators should translate the types of Chinese Jiu and drinking vessels as well as the drinking customs more accurately,so as to make western readers realize the significance of Li Po’s Jiu poems for understanding Chinese Jiu culture.
