摘要：Aluminum nanoparticles were fabricated by a physical vapor condensation
   method（DC arc discharge）.The samples were characterized by X-ray
   diffraction（XRD）,Transmission electron microscope（TEM） and galvanostatic
   cycling.Al particle size is about 100 nm,and it is coated by amorphous
   AI_2O_3.Anode slurries prepared were consisted of Al powder,acetylene
   black and polyvinylidene fluoride（PVDF） binder.The effects of current
   density on the electrochemical properties were investigated.The results
   show that Al electrode for the minimal current density delivers the
   highest initial discharge capacity（Li intercalation process） of 951.9
   mAh/g but cycle life is poor.Al electrode for the maximal current
   density delivers initial discharge capacities of 879.7 mAh/g and
   possesses relatively good cycleability.After the initial discharge only
   two composites（AILi and AI_2Li_3） in Al electrode are found,which
   correspond to the initial discharge capacity.
