The present document relates to multilayered dielectric composites for high-temperature applications and related methods.

Multilayered dielectric composites for high temperature applications

Disclosed herein is a dielectric composite comprising an organic polymer that has a glass transition temperature greater than or equal to about 250&#xb0; C.; and a dielectric filler present in an amount effective to impart to the dielectric composite a dielectric constant that varies by less than 5% over a temperature range of 25 &#xb0; C. to 300&#xb0; C., with an applied alternating electric field having a frequency of 10Hz and a maximum operating electric field strength of at least 250 megavolt per meter. Disclosed herein too is a method of manufacturing the dielectric composite and articles that contain the dielectric composite.

Disclosed herein is a dielectric composite comprising an organic polymer that has a glass transition temperature greater than or equal to about 250&#xb0; C.; and a dielectric filler present in an amount effective to impart to the dielectric composite a dielectric constant that varies by less than 5% over a temperature range of 25&#xb0; C. to 300&#xb0; C., with an applied alternating electric field having a frequency of 10Hz and a maximum operating electric field strength of at least 250 megavolt per meter. Disclosed herein too is a method of manufacturing the dielectric composite and articles that contain the dielectric composite.

We report a new class of single-ion electrolyte including pendant lithium perfluoroethyl sulfonates. Embodiments may be based on, for example, aromatic poly(arylene ether)s, polyphenylenes, or polyarylene sulfides. The microporous polymer film saturated with organic carbonates exhibits a nearly unity t, state-of-the-art conductivities (e.g. &#x3e;10S cmat room temperature) over a wide range of temperatures, high electrochemical stability, and outstanding mechanical properties, which enables the membrane to function as both ion conducting medium and separator in the batteries.
