CBMM EV Bus is only using niobium anode not cathode...shucks"The company executive also adds: "The technology that will be used in the batteries is the result of more than three years of research and development in partnership with Toshiba, in Japan. For the first time we are implementing this solution, which due to the use of Niobium oxide in the battery anode, will allow an ultra-fast charging operation, in less than 10 minutes, greater durability, service life and safety. This is, without a doubt, an important milestone for CBMM and for Brazil."
