Abstract: An electrolytic manganese dioxide improved for tool wear reduction, methods for preparing the improved electrolytic manganese dioxide and for preparing a positive-electrode precursor, and a primary battery are provided. One method includes displacement-washing neutralized electrolytic manganese dioxide with a solution including a corrosion inhibitor configured to be at a first predetermined concentration. The method further includes drying the washed electrolytic manganese dioxide to collect improved electrolytic manganese dioxide including the corrosion inhibitor configured to be at a second predetermined concentration within the improved electrolytic manganese dioxide to minimize corrosion of a metal material in contact with the improved electrolytic manganese dioxide. The corrosion inhibitor includes one of a benzoate salt, a phosphate salt, a carbonate salt, a metaborate salt, a tetraborate salt, a metaperiodate salt, and a meta-aluminate salt.

Abstract: A method for preparing treated electrolytic manganese dioxide and a battery including the treated electrolytic manganese dioxide as an electrode are provided. The method for treating the electrolytic manganese dioxide includes suspending milled electrolytic manganese dioxide in an aqueous solution heated to a temperature between ambient and boiling, and adjusting an acidity of the aqueous solution to a pH of less than 3.3. The method further includes agitating the suspended milled electrolytic manganese dioxide in the aqueous solution for a predetermined amount of time to dissolve metal-containing particulates in the milled electrolytic manganese dioxide.
