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.

A Polymer Electrolyte‐Based Rechargeable Lithium/Oxygen Battery
K. M. Abraham,Z. Jiang +1 more
TL;DR: In this paper, a rechargeable Li/O{sub 2} battery is reported, which consists of a conductive organic polymer electrolyte membrane sandwiched by a thin Li metal foil anode, and a thin carbon composite electrode on which oxygen, the electroactive cathode material, accessed from the environment, is reduced during discharge to generate electric power.

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
Rechargeable LI2O2 electrode for lithium batteries.
TL;DR: In this paper, the authors demonstrate two essential prerequisites for the successful operation of a rechargeable Li/O2 battery; that the Li2O2 formed on discharging such an O2 electrode is decomposed to Li and O2 on charging (shown here by in situ mass spectrometry), with or without a catalyst, and that charge/discharge cycling is sustainable for many cycles.

The Lithium–Oxygen Battery with Ether-Based Electrolytes

TL;DR: It is demonstrated that ether-based electrolytes are not suitable for rechargeable Li–O2 cells, although the ethers are more stable than the organic carbonates, the Li2O2 that forms on the first discharge is accompanied by electrolyte decomposition, to give a mixture of Li2CO3, HCO2 Li, CH3CO2Li, polyethers/ esters, CO2, and H2O.

Solvents' Critical Role in Nonaqueous Lithium-Oxygen Battery Electrochemistry.
TL;DR: Coulometry has to be coupled with quantitative gas consumption and evolution data to properly characterize the rechargeability of Li-air batteries, and chemical and electrochemical electrolyte stability in the presence of lithium peroxide and its intermediates is essential to produce a truly reversible Li-O2 electrochemistry.
