Room-temperature ionic liquids have a vast range of applications in chemical synthesis, indus- trial processing, and energy storage. For practical applications, the transport mechanism of charge carriers urgently need to be understood. In this paper we thus review the applications and progress of Broadband dielectric spectroscopy method on Ionic Liquids, summarize analytical methods and fundamental character- istics in three frequency domains, also project challenges and future trend, which play an important role and significance in depth understanding structural property and charge transport mechanism of Ionic liq- uids.
