Lithium-Oxygen Batteries and Related Systems: Potential, Status, and Future
Won-Jin Kwak,Won-Jin Kwak,Won-Jin Kwak,Rosy,Daniel Sharon,Daniel Sharon,Chun Xia,Hun Kim,Lee Johnson,Peter G. Bruce,Linda F. Nazar,Yang-Kook Sun,Aryeh A. Frimer,Malachi Noked,Stefan Freunberger,Stefan Freunberger,Doron Aurbach +16 more
TL;DR: This review is to provide an objective, comprehensive, and authoritative assessment of the intensive work invested in nonaqueous rechargeable metal-air batteries over the past few years, which identified the key problems and guides directions to solve them.
Journal ArticleDOI
Li–O2 cells with LiBr as an electrolyte and a redox mediator
Won-Jin Kwak,Daniel Hirshberg,Daniel Sharon,Michal Afri,Aryeh A. Frimer,Hun-Gi Jung,Doron Aurbach,Yang-Kook Sun +7 more
TL;DR: In this paper, the effect of other components in the cell, such as solvents and contaminants, on the lithium halide salt activity was examined, and it was concluded that low concentration of LiBr in diglyme solution can improve the cell performance with fewer side effects than LiI.
Journal ArticleDOI
A Mo2C/Carbon Nanotube Composite Cathode for Lithium-Oxygen Batteries with High Energy Efficiency and Long Cycle Life.
TL;DR: A nanostructured cathode based on molybdenum carbide nanoparticles (Mo2C) dispersed on carbon nanotubes, which dramatically increase the electrical efficiency up to 88% with a cycle life of more than 100 cycles.
Journal ArticleDOI
An Advanced Lithium–Air Battery Exploiting an Ionic Liquid-Based Electrolyte
Giuseppe Antonio Elia,Jusef Hassoun,Won-Jin Kwak,Yang-Kook Sun,B. Scrosati,Franziska Mueller,Dominic Bresser,Stefano Passerini,Philipp Oberhumer,Nikolaos Tsiouvaras,Jakub Reiter +10 more
TL;DR: The results of this extensive study demonstrate that this new Li/O2 cell is characterized by a stable electrode-electrolyte interface and a highly reversible charge-discharge cycling behavior, addressing one of the most critical issues preventing the practical application of lithium-oxygen batteries.
Journal ArticleDOI
Understanding the behavior of Li–oxygen cells containing LiI
Won-Jin Kwak,Daniel Hirshberg,Daniel Sharon,Hyeon-Ji Shin,Michal Afri,Jin Bum Park,Arnd Garsuch,Frederick Chesneau,Aryeh A. Frimer,Doron Aurbach,Yang-Kook Sun +10 more
TL;DR: In this article, the authors examined LiI as an electrolyte and additive in Li oxygen cells with ethereal electrolyte solutions and found that at high concentrations of LiI, the presence of the salt promotes a side reaction that forms LiOH as a major product.
