  • Superconducting cables made from bismuth-based superconducting wires with zero electrical resistance and strong electromagnets are expected to help conserve energy consumption due to small energy loss in power transmission. Related company: Sumitomo Electric USA

  • EV quick-charger connector assemblies from Sumitomo Electric provide a safe and easy-to-handle way to quickly power up electric vehicles and plug-in hybrid vehicles. Related company: Sumitomo Electric USA

  • Redox flow batteries are rechargeable batteries for use in power grid systems as a means to store electricity generated from solar power and wind power. They offer long service life with almost no degradation of electrodes and electrolytes, high safety due to being free of combustible materials, and availability of operation under normal temperatures.

  • Porous material CELMET is used to make various industrial products such as electrodes for NiMH batteries and carriers for industrial deodorization catalysts. It has significantly higher porosity than porous metals made from sintered metal powder or metallic fibers. Related company: Sumitomo Electric USA

  • Poreflon microfiltration membrane modules are ideal for wastewater treatment applications because of their high durability, superior chemical- and heat-resistance, washability, easy handling (hydrophilic treatment), and high water permeability. Related company: Sumitomo Electric USA
