| Outline of Final Research Achievements |
A patented tecnique for reclaiming degradated lead acid batteries, which contains addition of some surfactants into the electrolyte, were investigated to confirm that the tecnique can be avairable to produce a long-life battery. Charge-discharge tests of the batteries and analyses on the surface of the electrodes were performed. It was observed that the charge capacity was improved and the size of lead sulfate particles formed onto the electrode was depressed by addition on some surfactants with adequate concentrations. These results show usefulness of the tecnique to elongate the life of the batteries, however, the effects of the surfactants must be examined more.
