AbstractLayered oxide LiMO2 (Ni, Co, Mn) have been proposed as cathode materials for lithium-ion batteries. Mainly LiNiO2 is accepted as an attractive cathode material because of its various advantages such as low cost, high discharge capacity, good reversibility. The LiNi0.5Mn0.5O2 powders are synthesized by a sol-gel method using citric acid as a chelating agent. The structure of the synthesized material is analyzed by using XRD, FT-IR and the microstructures of the samples are observed by using FESEM. The intensities and positions of the peaks are in a good agreement with the previous results. The morphological changes are clearly observed as a result of manganese substitution. The Fourier transform infrared (FT-IR) spectra obtained with KBr pellet data reveal the structure of the oxide lattice constituted by LiO6 and NiO6 octahedra. The conductivity studies are characterized by (EIS) in the frequency range of 42 Hz to 1 MHz at room temperature to 120 °C. The dielectric properties are analyzed in the framework of complex dielectric permittivity and complex electric modulus formalisms. It indicates that the conductivity increases with increasing temperature. The fitting data of EIS plots replicate the non-Debye relaxation process with negative temperature coefficient of resistance (NTCR) behavior.

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).
