Abstract

In this work, rechargeable lithium-air battery using MnO₂/MWNTs nanocomposites as a catalyst was studied. MnO₂/MWNTs nanocomposites were synthesized by a hydrothermal method, and their physical and chemical properties were investigated. X-ray diffraction (XRD) was used to examine crystallinity and morphology was investigated by transmission electron microscopy (TEM). Charge- discharge behavior and cell impedance with electrolyte replacement were investigated, and charge-discharge capacity decreased with cycles mainly due to the decomposition of carbonate-based electrolyte.
