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 ... -
The Electrochemical Reaction Mechanism of Tin Phosphide with Sodium
(The Electrochemical Society, 2016-04-08)The sodiation mechanism of Sn4P3 was studied by ex-situ X-ray diffraction and Mössbauer effect spectroscopy. These results show that Sn4P3 is initially amorphized during sodiation, and suggest that upon further sodiation ... -
Electrochemistry and Thermal Behavior of SiOx Made by Reactive Gas Milling
(The Electrochemical Society, 2020-06-30)SiOx with various oxygen contents were synthesized from Si powder by a simple room-temperature ball milling method by controlling the air exposure time during milling. The resulting SiOx consists of nano and amorphous Si ... -
Electrochemistry of Catalytically Graphitized Ball Milled Carbon in Li Batteries
(The Electrochemical Society, 2016-03-03)High carbon Fe-C composites with starting concentrations of 10, 20, 30, and 40 wt% Fe (2.3 - 12.5 atomic % Fe) were prepared by ball milling followed by annealing. Increasing the Fe concentration and annealing temperature ... -
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 ... -
An Investigation of the Fe-Mn-Si System for Li-Ion Battery Negative Electrodes
(The Electrochemical Society, 2019-01-03)Fe-Mn-Si alloys prepared by ball milling were investigated as negative electrodes for Li-ion batteries. X-ray diffraction and room temperature 57Fe Mössbauer measurements were used to characterize alloy structure, which ... -
Li Insertion in Ball Milled Si-Mn Alloys
(The Electrochemical Society, 2018-06-08)Si1-xMnx (0 ≤ x ≤0.5, x=0.05)alloyswereprepared by ball milling and studied as negative electrode materials in Li cells. These alloys were found to be unique amongtransition metals. When x ≤ 0.35, the alloys are essentially ... -
Mössbauer and Electrochemical Investigations of Carbon-Rich Fe1-xCx Films (Preprint)
(2015 Elsevier Ltd., 2015-07-10)A thin film binary library of carbon-rich Fe1-xCx (0.47 ≤ x ≤ 0.97) alloys was prepared by combinatorial sputtering of carbon and iron. The sputtered library was characterized by X-ray diffraction and room temperature 57Fe ... -
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 ...
