Abstract
A manganese dioxide-containing cathode comprising heat-treated manganese dioxide, a binder and a conductive agent and wherein the walls of the pores of the cathode are coated with a vapor deposited organic solvent thereby reducing its affinity for absorbing moisture when exposed to a moisture environment for a fixed time period. The invention also relates to a method for producing the organic solvent treated manganese dioxide-containing cathode.
Claims8
A manganese dioxide for use as a cathode of a non-aqueous cell wherein at least the walls of the pores of the manganese dioxide exposed on the cathode surface are substantially coated with a vapor deposited organic solvent so as to reduce the affinity of the manganese dioxide for absorbing moisture.
