In recent years, research into potential substitutes for carbonaceous anode materials working at higher potentials in Li-ion batteries has picked up steam. It is imperative for safety reasons to swap out the low voltage graphite negative electrode ( 0.4V versus Li+/Li) with alternative materials functioning at greater voltages. The need is met by titanium and niobium oxides with the redox couples Ti4+/Ti3+, Nb5+/Nb4+, and Nb4+/Nb3+ operating at 1.5V vs. Li+/Li. It would be fascinating to compare TiTa2O7's isostructural behaviour to the electrochemical behaviour of TiNb2O7. Investigation of…mehr

Produktbeschreibung
In recent years, research into potential substitutes for carbonaceous anode materials working at higher potentials in Li-ion batteries has picked up steam. It is imperative for safety reasons to swap out the low voltage graphite negative electrode ( 0.4V versus Li+/Li) with alternative materials functioning at greater voltages. The need is met by titanium and niobium oxides with the redox couples Ti4+/Ti3+, Nb5+/Nb4+, and Nb4+/Nb3+ operating at 1.5V vs. Li+/Li. It would be fascinating to compare TiTa2O7's isostructural behaviour to the electrochemical behaviour of TiNb2O7. Investigation of W/Nb and Ti/Nb based phases with shear ReO3 structure is motivated by the potential for accessing the redox couples of Ti/Nb or W/Nb as well as the ease with which Li can be added to or removed from the ReO3 structure.
