| Abstract: | Spinels LiMn2O4 with different Cu-doping compositions were prepared by sol-gel process and the products were characterized by scaning electron micrographs , constant current charge-discharge and cyclic voltammogramso Results show that the charge/discharge capacity decrease with increasing of the doping compositions, however charge/discharge efficiency and cyclic properties increase. |
