High-performance lithium battery anodes using silicon nanowires.
The theoretical charge capacity for silicon nanowire battery electrodes is achieved and maintained a discharge capacity close to 75% of this maximum, with little fading during cycling.
Solution-processed metal nanowire mesh transparent electrodes.
Transparent conductive electrodes are important components of thin-film solar cells, light-emitting diodes, and many display technologies. Doped metal oxides are commonly used, but their optical…
Scalable coating and properties of transparent, flexible, silver nanowire electrodes.
The overall properties of transparent Ag NW electrodes meet the requirements of transparent electrodes for many applications and could be an immediate ITO replacement for flexible electronics and solar cells.
Stable cycling of double-walled silicon nanotube battery anodes through solid-electrolyte interphase control.
It is shown that anodes consisting of an active silicon nanotube surrounded by an ion-permeable silicon oxide shell can cycle over 6,000 times in half cells while retaining more than 85% of their initial capacity.
Nanostructured sulfur cathodes.
In this review, recent developments on nanostructured sulfur cathodes and mechanisms behind their operation are presented and discussed and progress on novel characterization of sulfurCathodes is summarized, as it has deepened the understanding of sulfur cathode and will guide further rational design of sulfur electrodes.
Nanowire Solar Cells
The nanowire geometry provides potential advantages over planar waferbased or thin-film solar cells in every step of the photoconversion process. These advantages include reduced reflection, extreme…
Optical absorption enhancement in amorphous silicon nanowire and nanocone arrays.
The fabrication of a-Si:H nanowires and nanocones function as both absorber and antireflection layers, which offer a promising approach to enhance the solar cell energy conversion efficiency.
Metal nanogrids, nanowires, and nanofibers for transparent electrodes
Metals possess the highest conductivity among all room-temperature materials; however, ultrathin metal films demonstrate decent optical transparency but poor sheet conductance due to electron…
A pomegranate-inspired nanoscale design for large-volume-change lithium battery anodes.
The design is inspired by the structure of a pomegranate, where single silicon nanoparticles are encapsulated by a conductive carbon layer that leaves enough room for expansion and contraction following lithiation and delithiation, resulting in superior cyclability and Coulombic efficiency.
Printable thin film supercapacitors using single-walled carbon nanotubes.
Using a printable aqueous gel electrolyte as well as an organic liquid electrolyte, the performances of the devices show very high energy and power densities which is comparable to performance in other SWCNT-based supercapacitor devices fabricated using different methods.
