Intercalation-type MoNb12O33 with a porous-microspherical nanoarchitecture is explored as the first molybdenum niobium oxide anode material for Li+ storage.
Ru 0.01 Ti 0.99 Nb 2 O 7 , with a much larger capacity than Li 4 Ti 5 O 12 , fulfils the requirements of high power and energy density for electric vehicles.
The research progress on Ti2Nb2xO4+5x is presented with emphases on the research history, structures, characteristics, working mechanisms, modifications and perspectives.
