Composites of {[(1-x-y) LiFe0.333Ni0.333 Co0.333] PO4}, xLi2FePO4F and yLiCoPO4system were synthesized using the sol-gel method. Stoichiometric weights of the mole-fraction of LiOH, FeCl2·4H2O and H3PO4, LiCl, Ni(NO3)2⋅6H2O, Co(Ac)2⋅4H2O, as starting materials of lithium, Iron, Nickel , and Cobalt, in 7 samples of the system, respectively. We exhibited Li1.167 Ni0.222 Co0.389 Fe0.388 PO4 is the best composition for cathode material in this study. Obviously, the used weight of cobalt in these samples is lower compared with LiCoO2 that is an advantage in view point of cost in this study. Charge-discharge haracteristics of the mentioned cathode materials were investigated by performing cycle tests in the range of 2.4–3.8 V (versus Li/Li+). Our results confirmed, although these kind systems can help for removing the disadvantage of cobalt which mainly is its cost and toxic, the performance of these kind systems are similar to the commercial cathode materials in Lithium Ion batteries (LIBs).

In the recent years, lithium-ion batteries have prevailed and dominated as the primary power sources for mobile electronic applications. Equally, their use in electric resources of transportation and other high-level applications is hindered to some certain extent. As a result, innovative fabrication of lithium-ion batteries based on best performing cathode materials should be developed as electrochemical performances of batteries depends largely on the electrode materials. Elemental doping and coating of cathode materials as a way of upgrading Li-ion batteries have gained interest and have modified most of the commonly used cathode materials. This has resulted in enhanced penetration of Li-ions, ionic mobility, electric conductivity and cyclability, with lesser capacity fading compared to traditional parent materials. The current paper reviews the role and effect of metal oxides as coatings for improvement of cathode materials in Li-ion batteries. For layered cathode materials, a clear evaluation of how metal oxide coatings sweep of metal ion dissolution, phase transitions and hydrofluoric acid attacks is detailed. Whereas the effective ways in which metal oxides suppress metal ion dissolution and capacity fading related to spinel cathode materials are explained. Lastly, challenges faced by olivine-type cathode materials, namely; low electronic conductivity and diffusion coefficient of Li+ ion, are discussed and recent findings on how metal oxide coatings could curb such limitations are outlined.
