Ultrafast Supercapacitors: History and Perspectives on Ultrafast Supercapacitors for AC Line Filtering (Adv. Energy Mater. 27/2021)

Abstract

In article number 2003306, Jinwoo Park and Woong Kim review how ultrafast supercapacitors have been developed for 60-Hz AC line filtering over the last decade and provide an outlook for future challenges and possibilities. Bicontinuous and bifunctional nanostructures of both electrodes and electrolytes are a particular focus as one of the key innovations in developing high-performance ultrafast supercapacitors.
