| description | Lithium-ion batteries are known for their high efficiency for storing electrical energy, especially for hybrid vehicles. In this research, the development of mixture composites in the cathode electrode of LIBs has been discussed and designed based on ternary solid solutions. We have given a novel synthesis and method preparation of cathode electrode materials to reduce costs while increasing the efficiency and simultaneity for the future of these technologies. The major problem in the LIBs is related to LiCoO<sub>2</sub> as a popular cathode material that, although it has a high efficiency, is expensive and very toxic. Therefore, the usage of a lower weight of cobalt compared to the LiCoO<sub>2</sub> cathode material is economically advantageous for this research. Several samples of the (1-x-y) LiCo<sub>1/3</sub>Ti<sub>1/3</sub>Fe<sub>1/3</sub>PO<sub>4</sub> xLi<sub>2</sub>MnPO<sub>4</sub> and yLiFePO<sub>4</sub> system were synthesized via sol–gel experiments. Various stoichiometric amounts of the LiNO<sub>3</sub>, Li<sub>2</sub>MnPO<sub>4</sub>, Mn (Ac)<sub>2</sub>. 4H<sub>2</sub>O, Co (Ac)<sub>2</sub>.4H<sub>2</sub>O, Ti(NO<sub>3</sub>)<sub>2</sub>.6H<sub>2</sub>O and LiFePO<sub>4</sub> have been used for several compositions of chrome, manganese, cobalt and titanium in 28 samples of (1-x-y) LiCo<sub>1/3</sub>Ti<sub>1/3</sub>Fe<sub>1/3</sub>PO<sub>4</sub>. By using thermal characterization, five samples have been selected due to their conditions in viewpoints of capacity and cyclability as well as activation energy, which is one of the major factors. These composites exhibited fairly consistent charge/discharge curves during the electrochemical testing. From the viewpoint of the physical and chemical properties, among these samples, the Li<sub>1.501</sub>Co<sub>0.389</sub>Ti<sub>0.055</sub>Fe<sub>0.055</sub>Mn<sub>0.501</sub>PO<sub>4</sub> structure has a high efficiency compared to other compositions. |
