Title:
Electrolysis manganese dioxide, a manufacturing method for the same, and a manufacturing method of a lithium manganese system compound oxide
Document Type and Number:
Japanese Patent JP5998510
Kind Code:
B2
Abstract:
The invention provides electrolytic a manganese dioxide with a BET specific surface area of 20 to 60 m 2 /g, and a volume of at least 0.023 cm 3 /g for pores with pore diameters of 2 to 200 nm. Also provided is a method for producing an electrolytic manganese dioxide including a step of suspending a manganese oxide in a sulfuric acid-manganese sulfate mixed solution to obtain the electrolytic manganese dioxide, wherein a manganese oxide particles are continuously mixed with a sulfuric acid-manganese sulfate mixed solution, for a manganese oxide particle concentration of 5 to 200 mg/L in the sulfuric acid-manganese sulfate mixed solution. Still further provided is a method for producing a lithium-manganese complex oxide, including a step of mixing the electrolytic manganese dioxide with a lithium compound and heat treating the mixture to obtain a lithium-manganese complex oxide.
