Electrochemical properties of LiMn2O4 cathode were investigated in three types Zn-containing electrolytes: lithium-zinc sulfate electrolyte (1M ZnSO4/2M Li2SO4), zinc (2MZnSO4) and lithium-zinc-manganese (1MZnSO4/2MLi2SO4/0.1MMnSO4). Cyclic voltammetry measurements demonstrated that is electrochemically inactive pure ZnSO4 after initial oxidation. The effect manganese (II) additive the zinc-man...

Efficient oxygen reduction reaction (ORR) electrocatalysts are the key to advancement of solid-state alkaline zinc–air batteries (ZAB). We demonstrate an electrocatalyst, spinel lithium-manganese oxide LiMn2O4 (LMO) by a simple hydrothermal method. Scanning electron microscope (SEM), X-ray diffraction (XRD), and Raman spectra indicate that as-synthesized presents nanoscale irregular-shaped part...
