MnO powder as anode material for lithium ion battery

摘要

MnO powder was synthesized by a facile pyrolysis method using Mn(Ac)_2·4H_2O powder as the starting material at 800°Cfor 3h under nitrogen atmosphere. The morphology and structure character of MnO powder was studied by Field-emission scanning electron microscopy (SEM) and X-ray Diffraction. The electrochemical performance of the product was evaluated by galvanostatic charge/discharge experiment. The results shows that MnO powder can deliver a capacity of 604mAh/g at current density of 0.1C, and a capacity retention of 88% is acquired after 150 cycles at 1C rate.
