Abstract: A method for preparing cathode material for a lithium primary battery includes an active cathode material and an active anode material. The active cathode material is manganese dioxide, and the active anode material is either one of lithium metal and lithium alloy. The method includes: a first kneading step in which a boron compound and a thickening agent are kneaded with a diluent to prepare a paste made by dissolving the boron compound in the diluent; a second kneading step in which the paste is kneaded with a conductive additive; and a third kneading step in which the paste obtained in the second kneading step is kneaded with the active cathode material and a binder to prepare the cathode material in slurry form.

Abstract: A method of manufacturing a battery electrode material in slurry form to be coated on a sheet-shaped current collector, the battery electrode material containing an electrode active material made of electrolytic manganese dioxide (EMD) and containing an aqueous binder. The method includes, as a process of mixing and kneading raw materials of the battery electrode material by using water as a solvent, mixing the electrode active material; mixing the binder; and mixing a neutralizing agent, the neutralizing agent being lithium hydroxide (LiOH).
