Stabilization of gamma sulfur at room temperature to enable the use of carbonate electrolyte in Li-S batteries
Autor: Rahul Pai, Arvinder Singh, Maureen H. Tang, Vibha Kalra
Publikováno v: Communications Chemistry, Vol 5, Iss 1, Pp 1-11 (2022)
Lithium sulfur batteries are an emerging energy storage medium, but their stability in carbonate electrolyte remains hampered by side-reactions. Here, the authors show that as-produced monoclinic gamma-sulfur on activated carbon nanofibers converts t

Dispersion and Stabilization of Alkylated 2D MXene in Nonpolar Solvents and Their Pseudocapacitive Behavior
Autor: Michael Carey, Zachary Hinton, Varun Natu, Rahul Pai, Maxim Sokol, Nicolas J. Alvarez, Vibha Kalra, Michel W. Barsoum
Publikováno v: Cell Reports Physical Science, Vol 1, Iss 4, Pp 100042- (2020)
Summary: To date, MXene dispersions have been mostly limited to polar solvents. Here, we show that when the lithium cations present between MXene multilayers after etching are exchanged with di(hydrogenated tallow)benzyl methyl ammonium chloride (DHT

A dual-role electrolyte additive for simultaneous polysulfide shuttle inhibition and redox mediation in sulfur batteries
Autor: Ayda Rafie, Vibha Kalra, Rahul Pai
Publikováno v: Journal of Materials Chemistry A. 9:26976-26988
In Li–S batteries, the insulating nature of sulfur and Li2S causes enormous challenges, such as high polarization and low active material utilization. The nucleation of the solid discharge product, Li2S, during the discharge cycle, and the activati

2D Ti3C2Tz MXene Synthesized by Water-free Etching of Ti3AlC2 in Polar Organic Solvents
Autor: Varun Natu, Rahul Pai, Michael Carey, Vibha Kalra, Michel W. Barsoum, Maxim Sokol
Publikováno v: Chem. 6:616-630
Summary The first MXene discovered, Ti3C2Tz, was synthesized by etching of the parent MAX phase, Ti3AlC2, in a solution of concentrated hydrofluoric acid. Since then, several other ways of synthesizing MXenes have been reported, such as electrochemic
