ULTRA-THIN CERAMIC COATING ON SEPARATOR FOR BATTERIES

Separators, high performance electrochemical devices, such as, batteries and capacitors, including the aforementioned separators, systems and methods for fabricating the same. In one implementation, a separator is provided. The separator comprises a polymer substrate (), capable of conducting ions, having a first surface and a second surface opposing the first surface. The separator further comprises a first ceramic-containing layer (), capable of conducting ions, formed on the first surface. The first ceramic-containing layer () has a thickness in arrange from about 1,000 nanometers to about 5000 nanometers. The separator further comprises a second ceramic-containing layer (), capable of conducting ions, formed on the second surface. The second ceramic-containing layer () is a binder-free ceramic-containing layer and has a thickness in arrange from about 1 nanometer to about 1,000 nanometers.
