Zinc oxide (ZnO) has been widely studied due to its low cost, outstanding stability and
high efficiency. One of the potential application of ZnO is to improve cycling
performance of a lithium ion batteries. Synthesis of ZnO with MgO to form ZnO/MgO
nanopowder has been carried by using simpler method. The synthesized of ZnO and
ZnO/MgO nanopowder are characterized by using Fourier transform infrared (FT-IR),
Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD). For FT-IR, the peak
at 500 cm -1 indicates that the formation of ZnO bonding while SEM morphology
showed that spherical ZnO and ZnO/MgO nanopowder were obtained. Electrochemical
property of ZnO and ZnO/MgO nanopowder are tested using galvanostatic
charge/discharge with Neware battery tester. The electrochemical testing result
indicates that the performance of ZnO/MgO nanopowder is decreased with a discharge
capacity of 117.04762 mAhg -1 at 0.1 C rate after 37 cycles. The results shows that the
battery performance can be improved.
