Benefited from the rational localized structure design, the carbon‐coated Si nanoparticles/TiO 2 nanotubes composited electrode (C@Si/TiNT) exhibits an ideal electrode thickness swelling, which is lower than 1% after the first cycle and increases to about 6.6% even after 1600 cycles.

The synthesis process used low-cost Si nanoparticles and electrospinning methods, both of which can be easily scaled. Silicon nanoparticles have a lower bulk density and larger specific surface area than bulk crystalline silicon. When exposed to air, the dispersion performance of these nanoparticles will be affected. Therefore, the nanoparticles should be stored in cool and dry room.

Recently, Si nanostructures-based lithium-ion battery anode, with sophisticated structure designs and process development, has made significant progress. However, low cost and scalable processes to produce these Si nanostructures remained as a challenge, which limits the widespread applications.

After charging–discharging for 200 cycles at a current density of 0.6 A g −1 , the specific capacity value of the ppy@Si anode is ∼954 mA h g −1 .

The unique optical properties of nanoparticles are highly sensitive in respect to particle shapes, sizes, and localization on a sample. This demands for a fully controlled fabrication process. The use of femtosecond laser pulses to generate and transfer nanoparticles from a bulk target towards a collector substrate is a promising approach. This process allows a controlled fabrication of

In this demonstration, Si nanoparticles are spin coated directly on silicon Nanosilicon.

The empty space around the Si nanoparticles allowed the electrode to successfully overcome these problems Our anode demonstrated a high gravimetric capacity (~1000 mAh/g based on the total mass) and long cycle life (200 cycles with 90% capacity retention). Upon lithiation, the Si nanoparticles undergo volume expansion, structural compaction, and appreciable coalescence in the confined space between the solid electrolyte layer and current collector in the solid-state cell to form a continuous film similar to that fabricated by the evaporation process. 2013-06-04 2013-10-12 Carbon‐Coated Si Nanoparticles Anchored between Reduced Graphene Oxides as an Extremely Reversible Anode Material for High Energy‐Density Li‐Ion Battery.
