Journal ArticleDOI

Li-O2 and Li-S batteries with high energy storage.

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

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

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.
