Electrochemical stability of ZnMn2O4: Understanding Zn-ion rechargeable battery capacity and degradation

Autor: Oleg Rubel, Thuy Nguyen Thanh Tran, Storm Gourley, Sriram Anand, Andrew Van Bommel, Brian D. Adams, Douglas G. Ivey, Drew Higgins

We present a refined Mn-Zn-H$_2$O Pourbaix diagram with the emphasis on parameters relevant for the Zn/MnO$_2$ rechargeable cells. It maps out boundaries of electrochemical stability for MnO$_2$, ZnMn$_2$O$_4$, ZnMn$_3$O$_7$, and MnOOH. The diagram h

Investigation of the Irreversible Capacity Loss in the Lithium-Rich Oxide Li[Li1/5Ni1/5Mn3/5]O2

Autor: Andrew van Bommel, L. J. Krause, J. R. Dahn

Publikováno v: Journal of The Electrochemical Society. 158:A731-A735

The lithium-rich transition metal oxides show a larger first charge capacity and larger cycling capacities than the non-lithium-rich transition metal oxides. The disadvantages of the lithium-rich transition metal oxides include relatively poor rate c

Coprecipitation Synthesis of NixMn1−x(OH)2 Mixed Hydroxides

Autor: Xuemei Zhao, J. R. Dahn, Andrew van Bommel, Fu Zhou, Aaron W. Rowe

Publikováno v: Chemistry of Materials. 22:1015-1021

Four separate coprecipitation routes were applied to the preparation of NixMn1−x(OH)2 mixed hydroxides with x = 1, 5/6, 2/3, 1/2, 1/3, and 0, beginning with divalent nitrates. The structure and morphology of the samples were studied by X-ray diffra

Analysis of the Growth Mechanism of Coprecipitated Spherical and Dense Nickel, Manganese, and Cobalt-Containing Hydroxides in the Presence of Aqueous Ammonia

Autor: Andrew van Bommel, J. R. Dahn

Publikováno v: Chemistry of Materials. 21:1500-1503

Spherical and dense metal hydroxides were synthesized with a coprecipitation reaction in the presence of aqueous ammonia. The growth of the particles was studied by tracking the tap density and morphology with reaction time. The dependence of pH on t

Dynamics of percolation and energetics in the clustering of water/AOT/oil microemulsions in the presence of ethanol amines

Autor: Rama M. Palepu, Danielle Chisholm, Andrew R. Glennie, Andrew van Bommel

Publikováno v: Canadian Journal of Chemistry. 84:412-420

Temperature-induced percolation in water/AOT/oil microemulsions in the presence of mono-, di-, and tri-ethanol amines have been studied using conductometric measurements. The percolation temperature of water/AOT/oil microemulsions depends on the natu

Self aggregation of binary mixtures of sodium dodecyl sulfate and polyoxyethylene alkyl ethers in aqueous solution

Autor: Rama M. Palepu, Subhash Chandra Bhattacharya, Andrew van Bommel, Karen M. Glenn

Publikováno v: Colloid and Polymer Science. 283:845-853

The mixed micelles of sodium dodecyl sulphate (SDS) with Brij35 and Brij 97 were studied separately by fluorescence measurement using pyrene as fluorescent probe. In the range of 0–1.0 mole fraction (X) of added SDS to Brij solutions, the cmc value

n-Alkanol induced clouding of Brij® 56 and the energetics of the process

Autor: Andrew van Bommel, Rama M. Palepu

Publikováno v: Colloids and Surfaces A: Physicochemical and Engineering Aspects. 233:109-115

The clouding behavior of the nonionic surfactant polyoxyethylene (10) cetyl ether (Brij ® 56) has been investigated in the presence of n -alkanols of varying chain lengths (C 1 –C 10 ). It was observed that the short-chained, water soluble n -alka
