Electrochemical Evaluation of PbO Nanoparticles as Anode for Lithium Ion Batteries (Technical Note)

PbO nanoparticles were synthesized using hydrothermal process. Scanning electron microscopy (SEM) was used in order to investigate of PbO powders. X-ray diffraction (XRD) pattern confirmed β-PbO formation during this process. The crystallite size of the powders was calculated using Scherrer formula about 74.6 nm. Electrochemical evaluation of the PbO nanoparticles as anode for Li-ion batteries shows that two reactions were occurred during the first discharge. Some intermediates also were seen during Pb alloying with Li. The cyclic loading of the PbO nanoparticles show reversible capacity higher than 125 mAh g-1
