The team developed an asymmetric supercapacitor device with a capacitance of 192.8 Fg-1 @ 1A g-1, an energy density of 54.6 Wh kg-1, a power density 700 W kg-1, and capacitance retention of about 82.5 ...

Three types of supercapacitor devices with variation in the electrode material are compared with respect to capacitance, pulse current, inter-nal resistance, power density and energy density.

When combined with another material as the positive electrode, such as RuO2, they resulted in an asymmetric supercapacitor device with a wide voltage range. In addition to higher energy density the ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

The asymmetric configuration of the masses of both electrodes in the supercapacitor has allowed to cover a higher potential window, resulting in an increase of the energy density of the three devices ...

Scientists initially used metal oxides as asymmetric supercapacitor electrodes, but ... The researchers tested their supercapacitor devices and showed they could cycle 20,000 times and exhibited ...
