Electrode which has been coated with a solid ion conductor which has a garnet-like crystal structure and has the stoichiometric composition L_7+XA_XG_3−XZr₂O₁₂

摘要

The invention id directed to an article which contains a solid ion conductor which has a garnet-like crystal structure and has the stoichiometric composition L_7+xA_xG_3−xZr₂O₁₂, whereL is in each case independently a monovalent cation,A is in each case independently a divalent cation,G is in each case independently a trivalent cation,0 ≦x≦3 andO can be partly or completely replaced by divalent or trivalent anion,wherein the article is a battery, an accumulator, a supercap, a fuel cell, sensor, a thermoelectric converter or an electrochromic device.
