Abstract: Implementations of the present disclosure generally relate to 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 a range from about 1,000 nanometers to about 5,000 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 a range from about 1 nanometer to about 1,000 nanometers.

Abstract: Polyimide binders and their polyamic precursors to be used for forming electrode structures are provided. The designed polyamic binder precursors are water-soluble, and the resulting polyimide binders are mechanically strong, electrochemically and thermally stable. The properties of polyimide binders have led to significant improvement in electrode compatibility towards new manufactural processes.

Abstract: 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 (131), 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 (136), capable of conducting ions, formed on the first surface. The first ceramic-containing layer (136) has a thickness in arrange from about 1,000 nanometers to about 5000 nanometers. The separator further comprises a second ceramic-containing layer (138), capable of conducting ions, formed on the second surface. The second ceramic-containing layer (138) is a binder-free ceramic-containing layer and has a thickness in arrange from about 1 nanometer to about 1,000 nanometers.

Abstract: Methods and apparatuses for processing lithium batteries with a laser source having a wide process window, high efficiency, and low cost are provided. The laser source is adapted to achieve high average power and a high frequency of picosecond pulses. The laser source can produce a line-shaped beam either in a fixed position or in scanning mode. The system can be operated in a dry room or vacuum environment. The system can include a debris removal mechanism, for example, inert gas flow, to the processing site to remove debris produced during the patterning process.
