Carbon Redox-Polymer-Gel Hybrid Supercapacitors
Energy storage devices that provide high specific power without compromising on specific energy are highly desirable for many electric-powered applications. Here, we demonstrate that polymer organic radical gel materials support fast bulk-redox charge storage, commensurate to surface double layer ion exchange at carbon electrodes. When integrated with a carbon-based electrical double layer capa...
متن کاملDouble polymer sheathed carbon nanotube supercapacitors show enhanced cycling stability.
Pseudo-materials are effective in boosting the specific capacitance of supercapacitors, but during service their degradation may also be very strong, causing reduced cycling stability. Here, we show that a carbon nanotube sponge grafted by two conventional pseudo-polymer layers in sequence can serve as a porous supercapacitor electrode with significantly enhanced cycling stability compared with...
متن کاملCarbon Nanotube-Based Supercapacitors
Due to the need for increased power performance, supercapacitors are emerging as an alternative to conventional electric energy storage devices. Because of their unique properties, carbon nanotubes are a promising material for next generation supercapacitors. Specifically, the use of nanotubes to construct supercapacitor electrodes can increases the power density and performance of supercapacit...
متن کاملCarbon Nanotube Supercapacitors
Supercapacitors (aka, electrochemical capacitors or ultracapacitors) are electrochemical energy storage devices that combine the high energy-storage-capability of conventional batteries with the high power-delivery-capability of conventional capacitors (Burke, 2000; Conway, 1999). Able to achieve higher power and longer cycle life than batteries, supercapacitors have been developed to provide p...
متن کاملThermal Properties of Hybrid Carbon Nanotube/Carbon Fiber Polymer Composites
Carbon fiber reinforced polymer (CFRP) composites possess many advantages for aircraft structures over conventional aluminum alloys: light weight, higher strengthand stiffness-to-weight ratio, and low life-cycle maintenance costs. However, the relatively low thermal and electrical conductivities of CFRP composites are deficient in providing structural safety under certain operational conditions...
