Energy storage devices (ESD) are getting significant attention regarding their ability to reduce fossil fuel usage. Batteries and electrochemical supercapacitors are two well-known ESDs with supercapacitors preferred for their high energy discharge potential. The metal oxides (MOs) with robust redox characteristics are ideal candidates for supercap...

Boron-nitrogen co-doped graphene nanoarchitectures were synthesized by annealing a freeze-dried precursor containing exfoliated graphene oxide (GO) nanosheets, ammonium borate, and polyvinyl alcohol (PVA). The microstructures and composition of nanocomposites were optimized and characterized systemically. Effects of a doping element on the electroc...

A better understanding of the energy-storage mechanisms in complex pseudocapacitive nanostructures is essential to improve the performances of nanohybrid supercapacitors. In this study, highly interface modified Nb2O5 nanoarrays, attached to graphene nanosheets, were carefully designed and synthesized. The electrochemical performances were evaluate...

Hierarchical nanostructures with highly exposed active surfaces for use in high-performance pseudocapacitors have attracted considerable attention. Herein, we developed a one-step method for the in situ growth of (NH4)(2)V10O25
A flexible three-dimensional carbon cloth/carbon fibers/NiCo2O4 composite electrode is prepared via a two step method: first growth carbon fibers on flexible carbon cloth; second coating NiCo2O4 on the carbon cloth/carbon fibers composite. The carbon cloth guarantees the flexibility of electrodes. The three-dimensional carbon cloth/carbon fibers c...
This paper reports a novel porous ternary nanohybrid based on NiMn2O4, reduced graphene oxide, and polyaniline (GNMOP) as a superior supercapacitor electrode material. GNMOP was fabricated using a hydrothermal-assisted thermal annealing method, followed by the conductive wrapping of polyaniline through in-situ polymerization. The structure and mor...
Direct metal laser sintering is used to create 3D hierarchical porous metallic scaffolds which are then functionalized with a co-electrodeposition of MnO2, Mn2O3, and doped conducting polymer. This approach of functionalizing metal 3D printed scaffolds thus opens new possibilities for structural energy storage devices with enhanced performance and ...
