Abstract
A study was undertaken to analyze the relationship between the electrochemical and the active sites on natural graphite of prismatic structure. The Reversible and irreversible was measured on natural graphite of predominantly two-dimensional platelets of average particle size varying from 2 to 40 mu m. The fraction of edge and basal plane sites was determined for ideal prismatic structures of different particle size. The passivation film was also examined at 500 mV by scanning electron microscopy and the structural change of the film during the first discharge. The intercalation-deintercalation reactions, which occur in metal-support graphite anode, are investigated using and galvanostatic. The effects of metals (Ag,) of average particle size varying from 1 to 17 mu m on the performance of LiC6 electrodes (graphite) are studied as well as the mechanism of hybrid reactions.
