Temporal evolution of anodization current of porous silicon samples
Temporal evolution of the anodization current of porous silicon samples was studied by means of a model of resistances connected in series that represented the temporal changes of the substrate and of the interface between ...
Dichlorosilane-derived nano-silicon inside hollow carbon spheres as a high-performance anode for Li-ion batteries
(Royal Society of Chemistry, 2017-03)
A novel and cost-effective synthesis of silicon nanocrystallites (<10 nm) sealed in hollow carbon spheres (nc-Si@HCS) is developed as a promising anode material for high-performance Li-ion batteries (LIBs). The preparation ...
Aligned pipe arrays formation by silicon anodic etching

Lifetime vs. rate capability: Understanding the role of FEC and VC in high-energy Li-ion batteries with nano-silicon anodes
(Elsevier, 2017-01)
Fluoroethylene carbonate (FEC) and vinylene carbonate (VC) are the most frequently used electrolyte components to enhance the lifetime of anode materials in Li-ion batteries, but for silicon it is still ambiguous when FEC ...
Field-emission properties of macroporous silicon grown at high anodization voltages
(Amer Inst PhysicsMelvilleEUA, 2005)
Local anodic oxidation on silicon (100) substrates using atomic force microscopy
(Universidad Nacional de Colombia Sede Medellín, 2012)
A characterization of local anodic oxidation using scanning probe microscopy is performed on a (100) silicon substrate. The formation of patterns varies as a function of voltage, humidity, and scanning speed. A set of ...
Anodization mechanism on SiC nanoparticle reinforced al matrix composites produced by power metallurgy
(Mdpi Ag, 2014-12-01)
Specimens of aluminum-based composites reinforced by silicon carbide nanoparticles (Al/SiCnp) produced by powder metallurgy (PM) were anodized under voltage control in tartaric-sulfuric acid (TSA). In this work, the influence ...
A Mapping of the Physical and Electrochemical Properties of Composite Lithium-Ion Batteries Anodes Made from Graphite, Sn, and Si
(Wiley-VCH, 2020-11)
Nowadays, there is an evident need to improve the current Li-ion battery systems, in order to make them more reliable, durable and safe. Regarding this objective, the application of composite materials –based mainly on the ...
