چکیده

We designed and fabricated binder-free, 3D porous silicon nanostructures for Li-ion battery anodes, where Si nanoparticles electrically contact current collectors via vertically grown silicon nanowires. When compared with a Si nanowire anode, the areal capacity was increased by a factor of 4 without having to use long, high temperature steps under vacuum that vapour– liquid–solid Si nanowire growth entails.

Isotropic to Anisotropic Transition Observed in Si Nanoparticles Lithiation by in situ TEM

Si is a promising candidate anode material for the next generation Li-ion battery because of its high capacity. However, Si inherently suffers from its large volume change (~300%) when alloyed with Li during the typical charge/discharge cycles, which degrades battery performance and causes potential safety issues. Understanding of microstructural evolutions of Si in the lithiation/delithiation ...

Field emission enhancement of Au-Si nano-particle-decorated silicon nanowires

Au-Si nano-particle-decorated silicon nanowire arrays have been fabricated by Au film deposition on silicon nanowire array substrates and then post-thermal annealing under hydrogen atmosphere. Field emission measurements illustrated that the turn-on fields of the non-annealed Au-coated SiNWs were 6.02 to 7.51 V/μm, higher than that of the as-grown silicon nanowires, which is about 5.01 V/μm. Me...

Nanoscale Heterogeneity of Multilayered Si Anodes with Embedded Nanoparticle Scaffolds for Li‐Ion Batteries

A new approach on the synthesis of Si anodes for Li-ion batteries is reported, combining advantages of both nanoparticulated and continuous Si films. A multilayered configuration prototype is proposed, comprising amorphous Si arranged in nanostructured, mechanically heterogeneous films, interspersed with Ta nanoparticle scaffolds. Particular structural features such as increased surface roughne...

Heteroepitaxial decoration of Ag nanoparticles on Si nanowires: a case study on Raman scattering and mapping.

Metallic nanoparticle-decorated silicon nanowires showed considerable promise in a wide range of applications such as photocatalytic conversion, surface-enhanced Raman scattering, and surface plasmonics. However there is still insufficient amount of Raman scattering in Si nanowires with such decoration. Here we report the heteroepitaxial growth of Ag nanoparticles on Si nanowires by a surface r...
