چکیده
Silicon used in this study: The active material we use in this work is made of Si nanoparticles. Its BET surface was found to be around 13 m².g-1. In addition, XRD (Figure S1) and TEM (Figure S2) characterizations were carried out on this material. Figure S1. XRD diagram of the active material used in this study. The diagram was acquired on a Brücker D8 Advance diffractometer θ-θ configuration with a Cu anticathode. Figure S2. TEM image of a Si particle. The Si nanoparticles are polycrystalline. The thickness of the oxide surface layer is found to be under 1 nm.

Failure mechanisms of nano-silicon anodes upon cycling: an electrode porosity evolution model.
With a specific capacity of 3600 mA h g(-1), silicon is a promising anode active material for Li-ion batteries (LIBs). However, because of the huge volume changes undergone by Si particles upon (de)alloying with lithium, Si electrodes suffer from rapid capacity fading. A deep understanding of the associated failure mechanisms is necessary to improve these electrochemical performances. To reach ...

A novel three-dimensional Tobacco mosaic virus assembled silicon anode is reported. This electrode combines genetically modified virus templates for the production of high aspect ratio nanofeatured surfaces with electroless deposition to produce an integrated nickel current collector followed by physical vapor deposition of a silicon layer to form a high capacity silicon anode. This composite s...
متن کاملEutectic Nano-Droplet Template Injection into Bulk Silicon to Construct Porous Frameworks with Concomitant Conformal Coating as Anodes for Li-Ion Batteries
Building porosity in monolithic materials is highly desired to design 3D electrodes, however ex-situ introduction or in-situ generation of nano-scale sacrificial template is still a great challenge. Here Al-Si eutectic droplet templates are uniformly injected into bulk Si through Al-induced solid-solid convection to construct a highly porous Si framework. This process is concomitant with proces...
