V2O5-LiBO2, V2O5-NiO-LiBO2 GLASSES AND THEIR COMPOSITES OBTAINED BY NITROGEN DOPING AND REDUCED GRAPHITE OXIDE BLENDING AS CATHODE ACTIVE MATERIALS

摘要

An electronically active glass has the composition (TxOy)z-(MuOv)w(Na/LiBO2)t wherein T is a transition metal selected from V and Mo, M is a metal selected from Ni, Co, Na, Al, Mn, Cr, Cu, Fe, Ti and mixtures thereof, x, y, u, and v are the stoichiometric coefficients resulting in a neutral compound, i.e. x=2y/(oxidation state of T) and u=2v/(oxidation state of M), z, w and t are weight-%, wherein z is 70-80, w is 0-20 t is 10-30, and the sum of z, w and t is 100 weight-%, in particular V2O5LiBO2 and V2O5NiOLiBO2.
