Torshiba NTO + Nanowe have patents on this.
Toshiba has prototyped a pouch lithium-ion battery that combines its new cathode with a niobium titanium oxide (NTO) anode (Figure 1). In tests, the battery demonstrates a high voltage of over 3V, fast charging to 80% of capacity in 5 minutes, high power performance, and excellent lifetime characteristics, even at a temperature of 60°C. Target applications for the battery range from power tools and industrial application that require high voltage with a small battery pack, up to electric vehicles.
