Cobalt Oxide Nanosheets for Reversible Lithium Ion Storage
Transition-metal oxide anodes, in particular, cobalt oxides, have attracted a great deal of interest since this class of materials can in principle deliver as high as ~3 times the capacity of commercial graphite anode (372 mAh/g). This paper reports a preparation of Co3O4 nanosheets by a hydrothermal technique. The obtained Co3O4 nanosheets were a few micrometers in sizes and ~100 nm in thickness. When evaluated as anode materials for lithium ion batteries, this product showed a very large reversible capacity of 802 mAh/g and a good high rate capability.
