SMM Advances High-Performance Cathode Materials for Next-Generation Batteries
SMM is forging ahead in the development of high-performance cathode materials, setting its sights on integration into all-solid-state batteries with the ambitious goal of achieving an energy density of 700 watt-hours per liter and a cost of 10,000 yen per kilowatt-hour for all-solid-state battery packs. Targeting commercialization by fiscal year 2008, the company has already established foundational technologies centered on lithium nickel acid (NCA) for lithium-ion secondary batteries (LiB) and the ternary system NMC, with pilot testing slated to commence in FY2013 at its battery research laboratory in Niihama City, Ehime Prefecture.
As one of the global leaders in cathode material production for rechargeable batteries, SMM has expanded its portfolio through the acquisition of the lithium lithium iron phosphate (LFP) business from Sumitomo Osaka Cement in 2010. This segment is being further developed in collaboration with Nano One Materials Corporation, a Canadian firm known for its eco-friendly process technology, to bolster the global market presence of LiBs, especially in electric vehicles.
SMM is also focused on developing cathode materials and near-infrared absorbing materials for automotive glass, contributing to lower carbon emissions. The company projects a reduction of 540,000 tons in CO2 emissions in FY2010 due to these products. Further reductions are anticipated with the operational start of the new Niihama Plant in Ehime Prefecture. Additionally, the Isoura Plant in Ehime Prefecture is transitioning its boiler fuel from heavy oil to LNG to further reduce carbon output.
Supported by the Green Innovation Fund Project of the New Energy and Industrial Technology Development Organization (NEDO), SMM's research spans various aspects of cathode material development, including composition, structure, and powder properties. The company is scheduled to complete lab bench testing by FY2011, with pilot testing in FY2012 and pre-commercialization by FY2015.
A second development building at the Battery Research Laboratories, also supported by the Fund, is under construction and set for completion in December 2013. This facility will house pilot operations for new processes in high-performance cathode material development, reinforcing SMM's commitment to next-generation battery technologies.
