Description
Summary:Fe-doped lithium-manganese spinel of the composition LiFe 0.05 Mn 1.95 O 4 was synthesized by means of a citric acid-aided route. The influence of annealing temperature on structural and morphological characteristics LiFe 0.05 Mn 1.95 O 4 is investigated by XRD and SEM methods. Specific and kinetic electrochemical characteristics of LiFe 0.05 Mn 1.95 O 4 in organic and aqueous electrolyte solutions were studied by galvanostatic cycling method and cyclic voltammetry. LiFe 0.05 Mn 1.95 O 4 samples annealed at temperatures of 700, 750, and 800 °C demonstrate specific capacity of 114, 102, and 109 mAh g −1 at the cycling current density of 0.5 C, respectively. The best cycling stability and rate performance with discharge currents up to 50 C were obtained in a case of the sample annealed at 750 °C. Graphical abstract
