Abstract
Particulate MnO, having simultaneously a micropore surface area greater than 8.0 m/g, desirably between about 8.0 and 13 m/g and BET surface area of between about 20 and 31 m/g within the context of an MnOhaving a total intraparticle porosity of between about 0.035 cm/g and 0.06 cm/g produces enhanced performance when employed as cathode active material in an electrochemical cell, particularly an alkaline cell. The average pore radius of the meso and macro pores within the MnO(meso-macro pore radius) is desirably greater than 32 Angstrom.
