Toshiba has developed a lithium-ion battery that uses niobium titanium oxide (NTO) as the negative electrode, achieving the same volumetric energy density as lithium iron phosphate (LFP) batteries while enabling ultra-fast charging for more than 10 times as many charge/discharge cycles.*1 Such batteries can be charged to approximately 70% in just 5 minutes and retain over 80% of their capacities even after more than 15,000 charge/discharge cycles, thus demonstrating longevity. In principle, lithium plating does not occur, ensuring safety in both low- and high-temperature environments. With high operational efficiency, the batteries are well suited for the electrification of large commercial vehicles such as buses and trucks, which frequently operate in harsh outdoor conditions. 
The ultra-fast charging capability and long-life performance are expected to reduce both the quantity of batteries needed and the frequency of replacement, thereby lowering initial investment and operating costs. In 2018, Toshiba entered into a joint development agreement with CBMM (Brazil) and Sojitz Corporation to move forward with commercialization. Since June 2024, the three companies have been conducting real-world demonstration tests with electric buses equipped with the developed battery at the Araxá Mine in Minas Gerais State, Brazil, in which CBMM has an ownership stake.*2

  • Based on Toshiba’s data for partial charge/discharge cycles (within a specified capacity range, not full cycles) under ultra-fast charging conditions. 
  • Toshiba, Sojitz, and CBMM have unveiled a prototype electric bus equipped with next-generation lithium-ion batteries that employ niobium titanium oxide and are capable of ultra-fast charging.
