Title:
ELECTROCHEMICAL DEVICE COMPRISING CARBON QUANTUM DOT IONIC COMPOUND ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2018/217044
Kind Code:
A1
Abstract:
The present invention relates to an electrochemical device comprising a carbon quantum dot ionic compound electrolyte and, more specifically, to an electrochemical device comprising a first electrode, a second electrode spaced from the first electrode, and an electrolyte filled between the first electrode and the second electrode, wherein the electrolyte comprises a carbon quantum dot ionic compound in the form of salts of metal cations and anions of graphene quantum dots having an average diameter within the range of 0.1-8 nanometers (nm) and having a surface charge of at most -20. The present invention provides an electrochemical device which not only allows an improvement in the reliability and performance of the device by improving selective ionic conduction with particular cations and inhibiting a side reaction caused by an electrolyte in the device, but also has drastically increased reliability, efficiency, and durability by applying, as the electrolyte, a carbon quantum dot ionic compound which can be applied as any of a liquid phase, a gel, and a solid phase and thus has high applicability.
