□ 연구개요
Development of high performance stacked cylindrical supercapacitor cells using 2D quantum sheets

□ 연구 목표대비 연구결과
The objective of this research work aims to develop high performance supercapacitors (SCs) towards applications in (i) electric vehicles (EVs), (ii) micro-supercapacitors computers/laptops, and (iii) backup energy for wind-pitch control that can operate over wide temperature (-40 to 140° C). Here, we are proposing the use of 2D quantum sheets (QSs) as an advanced electrode material for supercapacitors via synergetic effect of quantum capacitance (from electrode) and electrochemical capacitance (from electrode/electrolyte interfaces). Finally, we aimed to develop supercapacitor cells using these electrodes for applications such as (i) recovery of regenerative braking energy in electric vehicles, (ii) alternative energy source for wind turbines, and (iii) integrated on-chip supercapacitors for electronic devices.

□ 연구개발성과의 활용 계획 및 기대효과(연구개발결과의 중요성)
The prime objective of this research work aims to develop high performance supercapacitors (SCs) towards applications in (i) electric vehicles (EVs), (ii) micro-supercapacitors computers/laptops, and (iii) backup energy for wind-pitch control that can operate over wide temperature (-40 to 140° C). Here, we are proposing the use of 2D quantum sheets (QSs) as an advanced electrode material for supercapacitors via synergetic effect of quantum capacitance (from electrode) and electrochemical capacitance (from electrode/electrolyte interfaces). The origin and contribution of quantum capacitance will be evaluated by novel scanning electrochemical microscopy and electrochemical capacitance spectroscopy. Such a supercapacitor system using 2D quantum sheets lead to high energy density that can be comparable to lead-acid batteries, and even reachable to that of Li-ion batteries. Finally, we aimed to develop stacked supercapacitor cylindrical cells using these electrodes for applications such as (i) recovery of regenerative braking energy in electric vehicles, (ii) alternative energy source for wind turbines, and (iii) integrated on-chip supercapacitors for electronic devices.
