Vitreous materials with ionic conductivity, the preparation of same and the electrochemical applications thereof

摘要

Electrochemical devices use a vitreous material having a general formula xAaRb-yNmRc-zNnYp wherein A is Si, Ge, P, S, B, Nb, As, V, Cr or Mo; R is O, S or Se; N is Li, Na, K or Ag and Y is I, Br, Cl, F, ClO4, CF3, SO3, SCN or SO4 with the proviso that the material contain at least two salts NY. Such materials have increased cationic conductivity.
