A bstract : This review describes the properties and characteristics of a class of membranes formed by blends of a lithium salt, LiX, where X is preferably a large soft anion, such as ClO 4 or N(CF 3 SO 2 ) 2 , and a high molecular weight polymer containing Li + ‐coordinating group, such as polyethylene oxide (PEO) with the dispersion of selected ceramic powders, such as TiO 2 , Al 2 O 3 , and SiO 2 , at the nanoscale particle size. These nanocomposite membranes behave as lithium polymer electrolytes, that is, they exhibit a high lithium ion conductivity. Because of this property, the PEO‐LiX nanocomposite electrolytes may find an important application as separators in advanced, rechargeable lithium polymer batteries.
