ABSTRACT:
A primary alkaline battery includes a cathode having manganese dioxide and carbon particles, an anode, a separator and an alkaline electrolyte. The carbon particles include expanded graphite particles and non-expanded graphite particles. The expanded graphite particles have a kerosene absorption greater than about 2.7 milliliters per gram.
