Abstract

Aluminum-MnO2 �Al/MnO2� dry cells of “D” size configuration are investigated as an alternative to the Lechlanche dry cell, where aluminum is replaced for zinc as the anode, MnO2 as the cathode, and a mixture of aluminum chloride/ammonium chloride/chromium chloride as the electrolyte. Investigations regarding the optimization of conducting material, electrolyte composition, and electrochemical performance of the cell at different temperature and current drains �100, 200, and 400 mA� are carried out. Internal resistance and storage life of the fabricated aluminum dry cells are also evaluated. The results suggest that Al/MnO2 dry cells exhibit a superior performance than their Zn counterpart
