摘要:
Thin films of MnO were deposited by electron beam evaporation using a MnO or MnO2 source. The thin films were characterized by X-ray and electron diffraction. The Coulomb titration curve reveals a potential plateau of 2.9 V over the composition range 0.05 < x < 2.0. The chemical diffusion coefficient of lithium in thin films at 15-degrees-C is 2.7 x 10(-14) cm2/s for 0 < x < 0.01 and 2.2 x 10(-11) cm2/s for 0.02 < x < 0.06. Good reversibility for lithium insertion and extraction is demonstrated by cyclic voltammetry.
