Designing high voltage (>3 V) and stable electrochemical supercapacitors with low self-discharge is desirable for the applications in modern electronic devices. This work demonstrates a 4 V symmetric supercapacitor with stabilized cycling performance through atomic layer deposition (ALD) of alumina (Al<sub>2</sub> O<sub>3</sub> ) on the surface of activated carbon (AC). The 20-cycle ALD Al<sub>2</sub> O<sub>3</sub> coated AC delivers 84 % capacitance retention after 1000 charge/discharge cycles ...[more]
