Cherno Jaye, Daniel A. Fischer, Calvin Quilty, Patrick West, Garrett Wheeler, Lisa Housel, Christoph Kern, Killian Tallman, Lu Ma, Steven Ehrlich, Kenneth Takeuchi, David Bock, Amy Marschilok, Esther Takeuchi
Li-ion batteries capable of extreme fast charging (XFC) are in demand to facilitate widespread EV adoption. While the impact of fast charge on the negative electrode has been studied, degradation of state-of-the-art LiNi0.8Mn0.1Co0.1O2 (NMC811) under XFC

Hydrolysis-Controlled Transport of Water in Polymeric Coatings

October 12, 2021
Author(s)
Sanghun Lee, Tinh Nguyen, Jonathan W. Martin, E Byrd
Thermoset acrylic melamine coatings are widely used for exterior structures. These materials are formulated by reacting an acrylic polyol with an alkylated melamine. Because the reactions are reversible, acrylic-melamine coatings tend to hydrolyze during

Dynamic characterization of an alkali-ion-battery as a source for laser-cooled atoms

April 14, 2020
Author(s)
James P. McGilligan, Kaitlin R. Moore, Songbai Kang, R. Mott, A. Mis, C. Roper, Elizabeth Donley, John Kitching
We investigate a solid-state, reversible, alkali-ion-battery (AIB) capable of regulating the density of alkali atoms in a vacuum system used for the production of laser-cooled atoms. The cold-atom sample can be used with in-vacuum chronoamperometry as a
