Rare Metals 2007年第6期26卷 591-600页

作者： REN Li WANG Lixin AN Haoyuan ZHANG Fuqiang polymer Research Institute College of Chemical Engineering Hebei University of Technology Tianjin 300130 China

Lithium/polypyrrole （Li/PPy） batteries were fabricated using lithium sheet as cathode, PPy as anode, microporous membrane polypropylene/polyethylene/polypropylene （PP/PE/PP） composite as separator and LiPF6/ethylene carbonate-dimethyl carbonate-methyl ethyl carbonate （EC-DMC-EMC） as electrolyte. Polypyrrole was prepared by chemical polymerization. Certain fundamental electrochemical performances were investigated. Properties of the batteries were characterized and tested by SEM, galvanostatic charge/discharge tests, cyclic voltammetry （CV）, and a.c. impedance spectroscopy. The influences of separator, morphology, and conductivity of PPy anode, cold-molded pressure, and electric current on the performances of the batteries were studied. Using PP/PE/PP membranes as separator, the battery showed good storage stability and cycling property. The conductivity of materials rather than morphology affected the behavior of the battery. The higher the conductivity, the better performances the cells had. Proper cold-molded pressure 2. MPa of the anode pellet would make the properties of the cells good and the fitted charge/discharge current was 0.1 mA. The cells showed excellent performance with 97%-100% coulombic efficiency. The highest discharge capacity of 95.2.mAh/g was obtained.

Third East Asian polymer Conference

作者： Jen-taut Yen, Wei-Hua Yao, Li Cui, Wei Wei and Tao Jiang 1 Faculty of chemistry and material{2. Hubei university, Wuhan, China 2.Graduate School of polymer engineering National Taiwan university of{2. and Technology Taipei, Taiwan department of materials and Textiles, Oriental Institute of Technology, Pan-Chiao, 2.064 Taiwan, Republic of China

The blending and barrier properties of the MPAEVOH blends of modified polyamide (MPA) and ethylene vinyl alcohol copolymer (EVOH) were systematically investigated in this study. After blending MPA in EVOH resin, a noticeable "negative deviation" was found on the plot of oxygen permeation rate vs. MPA content, when the MPA contents present in MPAEVOH resins reach about 80 wt. %. The peak temperatures associated with the main melting endotherm of MPA and EVOH reduce significantly with increasing the EVOH and MPA contents present in MPAEVOH resins, respectively. The melting endotherm and X-ray diffraction peak associated with the EVOH crystal phases disappear gradually as the MPA contents present in MPAEVOH
