LiFePO4 particles doped with zinc oxide was synthesized via a hydrothermal route and used as cathode material for lithium-ion battery. Sample of preferable shape and structure was obtained by a concise and efficient process. ZnO doping into the LiFePO4 matrix was positively confirmed by the results of X-ray diffraction (XRD); high-resolution transmission electron microscopy (HRTEM); energy dispersive spectrometer (EDS), and X-ray photoelectron spectroscopy (XPS). LiFePO4 doped with ZnO tends to form nanometer-size and homogeneous particles, which can improve markedly the performance and stability of charge-discharge cycle. A specific discharge capacity of ZnO-doped LiFePO4 at 132.3 mAh g-1 was achieved, with 1.8% decrease after 100 cycles. Based on the cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) results, it has further shown that ZnO doping effectively reduces the impacts of polarization and transfer resistance during electrochemical processes.

“…kinetic properties of the cathode materials. For example, Arrebola et al [13] showed that an amorphously ZnO coating on the surface of the LNMO particles could upgrade its electrochemical properties, although this improvement are not quite satisfactory. Recently, Yang et al [20] reported that carbon-coated LNMO exhibited excellent rate capability and enhanced cyclic performance at a high rate at elevated temperature, which hinted that an electro-conductive coating layer was a new trend in terms of surface modification.…”

AlF 3 -coating is attempted to improve the performance of LiNi 0.5 Mn 1.5 O 4 cathode materials for Li-ion batteries. The prepared powders are characterized by scanning electron microscope, powder X-ray diffraction, charge/discharge, and impedance. The coated LiNi 0.5 Mn 1.5 O 4 samples show higher discharge capacity, better rate capability, and higher capacity retention than the uncoated samples. Among the coated samples, 1.0 mol% AlF 3 -coated sample shows highest capacity after charge-discharged at 30 mA/g for 3 cycles, but 4.0 mol% coated sample exhibits the highest capacity and cycling stability when cycled at high rate of 150 and 300 mA/g. The 40th cycle discharge capacity at 300 mA/g current still remains 114.8 mAh/g for 4.0 mol% AlF 3 -coated LiNi 0.5 Mn 1.5 O 4 , while only 84.3 mAh/g for the uncoated sample.
