Takehara Plant of MMS is located in the city center of Takehara, near the National Park of Seto Inland Sea. At present, 40 different products are manufactured at our plant, including non-ferrous metals, various battery materials and chemical products.
Commercial production of Electrolysis Manganese Dioxide (EMD), begun in 1949, was small about 5 ton/month, and the plant was gradually expanded so that it had a monthly capacity of 2, 100 tons in 1982.
Our EMD is specifically used for ZnC1₂, Alkaline and Lithium batteries, therefore EMD's high quality is very important. In this paper, the outline of our process and improvement in our plants and quality are described.
