“Using Niobium Titanium Oxide (NTO) as a next-generation anode material”

Toshiba have been focusing our attention on the possibility of Niobium Titanium Oxide (NTO) as a next-generation anode material that will help increase the battery capacity while maintaining the excellent characteristics of lithium titanium oxide (LTO), the conventional anode material of SCiB™. NTO has roughly three times higher theoretical volume capacity density than LTO while providing the advantages of LTO such as long life and rapid charging.
