Journal ArticleDOI
Li-O2 and Li-S batteries with high energy storage.
Peter G. Bruce,Stefan Freunberger,Laurence J. Hardwick,Laurence J. Hardwick,Jean-Marie Tarascon +4 more
TL;DR: The energy that can be stored in Li-air and Li-S cells is compared with Li-ion; the operation of the cells is discussed, as are the significant hurdles that will have to be overcome if such batteries are to succeed.
Journal ArticleDOI
Challenges Facing Lithium Batteries and Electrical Double‐Layer Capacitors
Nam-Soon Choi,Zonghai Chen,Stefan Freunberger,Xiulei Ji,Yang-Kook Sun,Khalil Amine,Gleb Yushin,Linda F. Nazar,Jaephil Cho,Peter G. Bruce +9 more
TL;DR: The Review will consider some of the current scientific issues underpinning lithium batteries and electric double-layer capacitors.
Journal ArticleDOI
A reversible and higher-rate Li-O2 battery.
TL;DR: Operation of the rechargeable Li-O2 battery depends critically on repeated and highly reversible formation/decomposition of lithium peroxide (Li2O2) at the cathode upon cycling, and it is shown that this process is possible with the use of a dimethyl sulfoxide electrolyte and a porous gold electrode.
Journal ArticleDOI
Reactions in the Rechargeable Lithium–O2 Battery with Alkyl Carbonate Electrolytes
Stefan Freunberger,Yi Chen,Zhangquan Peng,John M. Griffin,Laurence J. Hardwick,Fanny Bardé,Petr Novák,Peter G. Bruce +7 more
TL;DR: Mechanisms are proposed for the reactions on discharge and charge that are consistent with the widely observed voltage gap in Li-O(2) cells.
Journal ArticleDOI
The carbon electrode in nonaqueous Li-O2 cells.
TL;DR: Analyzing carbon cathodes, cycled in Li-O(2) cells between 2 and 4 V, using acid treatment and Fenton's reagent, and combined with differential electrochemical mass spectrometry and FTIR demonstrates the following: Carbon is relatively stable below 3.5 V, but is unstable on charging above 3.
