- Abstract
- The nano-sized cobalt powders were prepared using a pulsed wire evaporation method. The cobalt powder had a spherical shape with a diameter of less than 200 nm. A cobalt electrode was prepared from the nano-sized cobalt powder, acetylene black and polyvinylidene fluoride. During the first discharge, the Li/Co cell showed a plateau potential of 0.7V and a capacity of 440mAh/g. The nano-sized Co electrode had a stable reversible lithium storage capacity of approximately 280mAh g(-1) after 30 cycles.
