Lithium-graphite secondary battery

Reactions occurring at the positive and negative electrodes and in the solution phase of cells of the type Li/LiClO4, DMSU/Graphite have been studied. Experiments were performed in an H-cell wherein the two electrodes of the cell were isolated in compartments separated by a porous glass frit. Discharge capability of 36 hours at a current density of 2 mA/cm square have been demonstrated. Discharge potential was about 3.00 V measured versus a lithium wire reference electrode. The effect of operating current on cell performance has been studied. The role of each component of the battery in the charging and discharging reactions has been investigated.
