The Electrochemical Behavior of Polyimide Binders in Li and Na Cells
(The Electrochemical Society, 2015-12-09)
The electrochemistry of aromatic and aliphatic polyimide binders was characterized in composite coatings for Li-ion and Na-ion battery negative electrodes. Aromatic polyimide was found to have a large first lithiation ...
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 ...
Combinatorial Study of the Si-Sn-O System as Negative Electrode Materials in Li-Ion Cells
(The Electrochemical Society, 2015-11-17)
SixSnyO1-x-y films with 0.45 < x < 0.80, 0.05 < y < 0.35, and 0.05 < (1-x-y) < 0.40 have been prepared using a magnetron sputtering method. All compositions had an amorphous structure and good capacity retention. Reversible ...
Li15Si4 Formation in Silicon Thin Film Negative Electrodes
(The Electrochemical Society, 2015-11-19)
The conditions for Li15Si4 formation in Si thin film negative electrodes was studied during charge and discharge cycling in lithium cells. It was found that Li15Si4 formation can be suppressed during cycling of Si thin ...
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 ...
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 ...
