Development of Megawatt-Class Electric Power Generation and Storage System with World’s Largest Redox Flow Battery
Sumitomo Electric Industries has successfully developed a megawatt-class electric power generation/storage system which consists of the world’s largest redox flow battery and Japan’s largest concentrator photovoltaic (CPV) units. Sumitomo is planning to demonstrate the megawatt-class system on the premises of the Yokohama Works (Sakae-Ku Yokohama) in July 2012. The system is comprised of 28 CPV units with maximum total power generation of 200 kW as its energy source and one redox flow battery with capacity of 1MW x 5 hours as a storage facility of CPV-generated power. By employing the EMS (Energy Management System) , the system is indented to regulate the amount of electricity provided by power companies using the redox flow battery’s charge/discharge control function.

Development of a new cBN Grade Material with World’s highest cBN Content for Cast-Iron and Sintered-Alloy Cutting
Sumitomo Electric Industries has successfully developed a new cBN grade “SUMIBORON BN7000” for general cast-iron and sintered-alloy cutting purposes. The new “SUMIBORON BN7000” has world’s highest cBN content. Cubic boron nitride or otherwise known as cBN is the second hardest material, after diamond. cBN is made treating CBN powder and a binder under high temperature and pressure. Sintered cBN is used for cutting tool material for high-speed machining of hard to cut ferrous metals, such as automobile steels as well as cast irons, where tougher and longer-life tool materials are in demand, especially in area of machining cast-iron engine blocks and sintered-alloy parts.

Development of Porous Aluminum with Excellent Electrical Conductivity and Corrosion Resistance for use in Lithium-ion Batteries
Sumitomo Electric Industries has developed a new porous aluminum, “Aluminum-Celmet”. The Celmet in general feature high porosity of up to 98%, considerably higher than other porous metals, such as nonwoven metal fabric and foam metals. It holds a three dimensional mesh-like structure that forms interconnected, open and spherical pores, making it easy to process the Celmet into various shapes through cutting and stamping. Celmet has recently been used as a positive electrode current collector in hybrid vehicles nickel-hydrogen batteries. The new Aluminum Celmet is very light, with specific gravity which is one-third that of nickel. Read more
Achievement of High Capacity of 109 Terabit Per Second Optical Fiber Transmission by Japanese Researchers
Group of researchers at National Institute of Information and Communication Technology (NICT) have succeeded in transmission of 109 Terabit per second (Tbits/s) optical signal using a new class of optical fiber. The experiment was done in collaboration with OPTOQUEST and Sumitomo Electric Industries. The result is the world record, exceeding the previously set record at 69.1 Tbit/s. Read more
Development of New AZ91 Magnesium Alloy Sheet by SUMITOMO Electric Industries
Magnesium, among the metal in use is the lightest, with specific gravity lower than quarter of iron and around two third of aluminum. Furthermore, it features an outstanding strength and rigidity per weight in comparison to iron and aluminum contributing in manufacturing strong and light products. Adding to this, the magnesium is considered to be an environmentally friendly metal due to its high energy efficiency and recyclable properties, not to forget its abundance in nature. Based on these properties , Sumitomo Electric has developed AZ91 magnesium alloy sheet and its commercial production through a unique continuous casting process for the first time in the world.
