NixSi1-x Alloys Prepared by Mechanical Milling as Negative Electrode Materials for Lithium Ion Batteries
(The Electrochemical Society, 2015-10-29)
NixSi1-x (0 ≤ x ≤ 0.5, x = 0.05) alloys were prepared by ball milling and studied as anode materials for lithium ion batteries. Nanocrystalline Si/NiSi2 phases were formed for x ≤ 0.25. The NiSi phase was observed for ...
Structural and Electrochemical Investigation of FexSi1-x Thin Films in Li Cells
(The Electrochemical Society, 2016-07-20)
FexSi1-x thin films with 0 ≤ x ≤ 0.46 have been prepared by combinatorial sputtering and their electrochemical properties have been studied in Li half-cells. X-ray diffraction showed that all of the films had an amorphous ...
The Electrochemistry of Amorphous Si-B Thin Film Electrodes in Li Cells
(The Electrochemical Society, 2015-11-14)
Abstract
Si1-xBx thin films of 0.071 ≤ x ≤ 0.950 have been synthesized using combinational sputtering. All Si1-xBx film compositions had a highly amorphous structure consisting of amorphous Si and B phases, as characterized ...
Electrochemistry of CuxSi1−x Alloys in Li Cells
(The Electrochemical Society, 2016-04-20)
The structure and electrochemistry in lithium cells of sputtered thin films and ball milled alloys in the Cu-Si system (0 ≤ x ≤ 0.60 in CuxSi1−x) were investigated. Both thin films and ball milled Cu-Si alloys showed the ...
Electrochemical Activity of Nano-NiSi2 in Li Cells
(The Electrochemical Society, 2016-09-09)
Crystalline and nanocrystalline NiSi2 were studied as negative electrode materials in Li cells. Crystalline NiSi2 was found to be inactive toward lithiation/delithiation. However, it was found that NiSi2 becomes active ...
Combinatorial Investigations of Ni-Si Negative Electrode Materials for Li-Ion Batteries
(IOPscience, 2015-06-30)
Sputtered thin films in the Ni-Si system (0 ≤ x ≤ 0.65 in NixSi1-x) were studied for use as anode materials in Li-ion cells. All compositions were found to be amorphous. The Ni in Ni-Si films was found to suppress the ...
