Methods, devices and systems for activated carbon supercapacitors with macroporous electrodes

摘要

Energy storage devices comprising carbon-based electrodes and/or redox electrolytes are disclosed herein. In some embodiments, the carbon-based electrodes comprise laser-scribed activated carbon comprising one or more micro-channels. In some embodiments, the redox electrolytes comprise a ferricyanide/ferrocyanide redox couple. Also described are processes, methods, protocols and the like for manufacturing carbon-based electrodes comprising micro-channels for use in high energy storage devices such as supercapacitors, and for manufacturing high energy storage devices comprising redox electrolytes.
