![عکس صفحه اول مقاله: Synthesis and characterization of LiFeO2 and LiFe0.9Co0.1O2 as cathode materials for Li-ion cells Synthesis and characterization of LiFeO2 and LiFe0.9Co0.1O2 as cathode materials for Li-ion cells](/preview/png/1287304.png)
The solution-combustion route is beneficial for fast and easy synthesis of cathode materials for Li-ion cells. LiFeO2 synthesized by this method results in an amorphous phase that exhibits poor electrochemical activity with an initial specific capacity of only about 80 mAh g−1 and on annealing it transforms into an electrochemically inactive phase. On the other hand, α-NaFeO2 synthesized by a solution-combustion method and subjected to Na+/Li+ exchange by refluxing with LiBr solution in n-hexanol to obtain layered LiFeO2, exhibits an initial specific capacity of about 205 mAh g−1 with capacity fading after prolonged charge–discharge cycling. LiFe0.9Co0.1O2, synthesized by the same route, shows a stable specific capacity of about 190 mAh g−1.
