Quantification of lithium inventory loss in micro silicon anode via titration-gas chromatography

Synthesis of Hard Carbon- Silicon Nanocomposite as Anode Active Material for Lithium-Ion Batteries

In this research, using phenolic resin as the precursor of carbon and various amounts of ethylene glycol as a pore former, porous samples of hard carbon were synthesized. Samples were characterized by x-ray diffraction (XRD) and N2 adsorption-desorption methods. Broad diffraction peaks represent the amorphous structure of samples. Moreover, the gas adsorption-desorption curves showed that the a...

Virus-enabled silicon anode for lithium-ion batteries.

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...

Silicon Based Composite Anode for Lithium Ion Battery

Solid Electrolyte Interphase Formation on Silicon and Lithium Titanate Anode Materials in Lithium-Ion Batteries

Aiming at an improved knowledge of the formation of the solid electrolyte interphase (SEI), as basis for the safe and efficient use of new anode materials, we investigated the SEI formation on silicon and lithium titanate (LTO) anodes by electrochemical impedance spectroscopy (EIS) and ex situ X-ray photoelectron spectroscopy (XPS) measurements. While the EIS measurements performed at equidista...

Micro Gas Chromatography for Liquid Petroleum Gas's

For years, microGC analysis has been useful as a powerful tool for the fast and reliable analyses of natural gas and other gaseous matrices; but, it is yet to prove its capabilities for liquid samples. In this paper, we present a unique gasifying system for volatile liquid sample introduction in a microGC. The system has been tested with a wide range of different samples: liquefied gases (ethan...
