Abstract

The invention relates to an improved method for preparing a lithiated manganese dioxide having a stabilized η-MnO2-type crystal structure whereby an essentially dry mixture of manganese dioxide and a lithium slat is subjected to a mechanical activation process in the presence of milling media. The mechanical activation process serves to promote partial ion-exchange of protons present in the manganese dioxide crystal lattice and on the surface of the manganese dioxide particles by lithium cations. The formed lithium ion-exchanged intermediate product is heat-treated to form a lithiated manganese dioxide product having a η-MnO2-type crystal structure that can be advantageously included in the cathode of a lithium primary electrochemical cell.
