Abstract

An electrochemical cell, such as Li-Ion, having (a) a positive electrode; (b) a negative electrode, (c) a porous inorganic/organic composite layer interposed between the positive electrode and the negative electrode, and (d) an electrolyte comprising a lithium salt and a non-aqueous solvent. The composite layer includes inorganic nanoparticles and a binder to form a nanocomposite separator (NCS). In addition to the composite layer, the electrochemical cell includes a porous separator.
