ALKALI-ION CONDUCTIVE SEPARATOR ASSEMBLY FOR RECHARGEABLE ELECTROCHEMICAL CELLS

摘要

Disclosed is an alkali-ion conducting separator assembly comprising a porous membrane (A) and an alkali-ion conducting film (B) placed on one major surface of the porous membrane (A), wherein the alkali-ion conducting film (B) comprises an inorganic material of the general formula (I): (L1+[(12−u)2+wv)−xm−[(3−y)3+yn]−[(2−z)5+zp]Im+x](A3+3−yan+y)(B5+2−zbp+z)(O2−12−uDv−w) (I) Further disclosed is a process for producing such an alkali-ion conducting separator assembly and a rechargeable electrochemical cell comprising such an alkali-ion conducting separator assembly.
