Abstract
High-capacity Li[Li0.2Mn0.54Ni0.13Co0.13]O2 has been successfully synthesized as a cathode material for Li-ion battery by hydrothermal method. The prepared materials are characterized by XRD, SEM, TEM, EDS, XPS and electrochemical measurements. The XRD result shows that Li[Li0.2Mn0.54Ni0.13Co0.13]O2 material formed a pure phase. SEM and TEM images present a uniformly distributed nanosize of 20-200 nm. The results of CV, charge-discharge tests indicate that this material possesses high discharge capacity and quite good cycling stability. It delivers 251.9 mAh gâ1 and 107.5 mAh gâ1 for the first cycle and remains 139.4 mAh gâ1 and 82.7 mAh gâ1 after 500 cycles, respectively, corresponding to 1 C and 10 C.
