Title: (EN) HIGH-TEMPERATURE SUPERCAPACITORS CONTAINING SURFACE ACTIVE IONIC LIQUIDS
Abstract: front page image
(EN)

Disclosed are capacitors containing surface active ionic liquids, and methods of use. The capacitors have high capacitance and function over broad ranges of temperature, and are particularly appropriate for high-temperature (˜200° C.) applications.
