FREE STANDING NANOSTRUCTURED ANODES FOR LI-ION RECHARGEABLE BATTERIES
The free standing nanorodes of aluminum and cobalt oxides were grown on electrode and tested as the anodes directly in the half-cell. The average diameter and length of the nanorods are 80 nm and 200 nm respectively. The aligned nanorods demonstrated high initial capacity from 1200-1400 mAh/g at rate of 0.5C. The gradually decrease of initial capacity was observed. The preliminary characterization shows that the changes of the crystalline structure and morphology during cycling may be responsible for the capacity decay.
