Understanding LiOH Chemistry in a Ruthenium Catalyzed Li-O2 Battery
Tao Liu, Zigeng Liu, Gunwoo Kim +3
Non-aqueous Li-O2 batteries are promising for next generation energy storage. New battery chemistries based on LiOH, rather than Li2O2, have recently been reported in systems with…
Identifying the Structural Basis for the Increased Stability of the Solid Electrolyte Interphase Formed on Silicon with the Additive Fluoroethylene Carbonate
Yanting Jin, Nis-Julian H. Kneusels, Pieter C. M. M. Magusin +8
To elucidate the role of fluoroethylene carbonate (FEC) as an additive in the standard carbonate-based electrolyte for Li-ion batteries, the solid electrolyte interphase (SEI) form…
Exfoliation of layered Na-ion anode material Na2Ti3O7 for enhanced capacity and cyclability
Maria A. Tsiamtsouri, Phoebe K. Allan, Andrew J. Pell +6
We report the exfoliation of layered Na2Ti3O7, a promising anode material for Na-ion batteries, and restacking using HNO3 and NaOH to form H-Ti3O7 and Na(x)-Ti3O7 compositions, res…
The Effect of Water on Quinone Redox Mediators in Non- aqueous Li-O2 Batteries
Tao Liu, James T. Frith, Gunwoo Kim +8
The parasitic reactions associated with reduced oxygen species and the difficulty in achieving the high theoretical capacity have been major issues plaguing development of practica…
Surface Sensitive NMR Detection of the SEI Layer on Reduced Graphene Oxide
Michal Leskes, Gunwoo Kim, Tao Liu +5
The solid electrolyte interphase (SEI) is detrimental for rechargeable batteries performance and lifetime. Understanding its formation requires analytical techniques that provide m…
Mechanistic Insights into the Challenges of Cycling a Non-aqueous Na-O2 Battery
Tao Liu, Gunwoo Kim, Mike T. L. Casford +1
Superoxide-based non-aqueous metal oxygen batteries have received considerable research attention, as they exhibit high energy densities and round-trip efficiencies. The cycling pe…
