Abstract
The effect of heating the electrolytic manganese dioxide (EMD) obtained from the Indian ore on the performance of LiIMnO
button cells has been investigated. Portions of the MnO samples were heated to 373K. 573K and 1023K respectively. Lithium
perchlorate solutions in propylene carbonate of concentrations 0.5M. 1M. 1.5M and 2M were used as electrolyte solution.
Button cells of 20 mm dia. were fabricated with each MnO sample and with the different concentrations of electrolyte solution.
Cellulose material was used as separator. Cells were also assembled with mixed solvents of propylene carbonate and
dimethoxy ethane.
These cells were discharged at 50A. lOOA and 200A. The internal resistances of these celk have been determined. It was
observed that the MnO sample heated at 573K with one molar lithium perchlorate solution in propylene carbonate gave the
best performance
