Název v původním jazyce

Enhanced Charge Storage Mechanism and Long-Term Cycling Stability in Diamondized Titania Nanocomposite Supercapacitors Operating in Aqueous Electrolytes

Popis výsledku v původním jazyce

The long cycle life stability and high energy density are limiting broader feasible applications of supercapacitors (SCs). The novel diamondized titania nanocomposite SCs deliver high power and energy densities along with high capacitance retention rates. SC electrodes were fabricated utilizing a combination of Ti anodization followed by chemical vapor deposition resulting in the simultaneous growth of the complex boron-doped diamond (BDD)/TiC interface. The first-principles simulations along with extended molecular investigations conducted by bright-field transmission electron microscopy and high resolution-scanning electron microscopy revealed that capacitive phenomena are delivered by nanoporous, multifaceted, and substoichiometric TiC, forming clusters at the lateral surfaces of titania nanotubes.
