Abstract

Layered Li-birnessite was prepared by means of oxidizing Mn2+ with O2 gas in alkaline media.The as-prepared sample was characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),BET and thermogravimetric/diffenential thermal analysis(TG/DTA) techniques.The electrochemical properties of the material were also investigated.The results show that such a Li-birnessite consists of well-crystallized spherical particles with an interlayer distance of 0.70 nm.The Li-birnessite delivered a high discharge capacity of 203 mAh/g at a rate of 0.2 C(40 mA/g),and had good rate capability as well.
