Abstract
Abstract >> Recent years, supercapacitors have been attracting a growing attention as an efficient energy storage,due to their long-lifetime, device reliability, simple device structure and operation mechanism and, most importantly,high power density. Along with the increasing interest in flexible/stretchable electronics, the supercapacitors withcompatible mechanical properties have been also required. A eutectic gallium-indium (EGaIn) liquid metal couldbe a strong candidate as a soft electrode material of the supercapacitors because of its insulating surface oxidelayer for electric double layer formation. Here, we report the electrochemical study on the charging/reaction process at the interface of EGaIn liquid metal and electrolyte. Numerical fitting of the charging current curves provides the capacitance of EGaIn/insulating layer/electrolyte (~38 F/m 2 ). This value is two orders of magnitude higherthan a capacitance of a general metal electrode/electrolyte interface.Key words : Eutectic Gallium-indium liquid metal(갈륨-인듐 공융합금), Supercapacitor(수퍼커패시터), Oxide layer(산화막), Electrochemistry(전기화학), Electric double-layer(전기 이중층)
