| Abstract |
Li-O2 battery research at a fundamental level remains critical, and nature of reactions and stability are paramount for realising the promise of the Li-O2 system. We report that ITO nanocrystals with supported 1-2 nm OER catalyst Ru/RuOx nanoparticles demonstrate efficient OER processes, significantly reducing the cell's recharge overpotential, and maintain catalytic activity to promote a consistent cycling discharge potential in Li-O2 cells even when the ITO support nanocrystals deteriorate from the very first cycle. The Ru/RuOx nanoparticles lower the charge overpotential compared to ITO and carbon-only cathodes and have the greatest effect in DMSO electrolytes with a solution-processable F-free CMC binder (< 3.5 V) vs PVDF. Ru/RuOx/ITO nanocrystalline materials in DMSO provide efficient Li2O2 decomposition from within the cathode during cycling. We demonstrate that the ITO is actually unstable from the first cycle and completely dissolves by chemical etching, but Ru/RuOx NPs remain effective OER catalysts for Li2O2 during cycling. CMC binders avoid PVDF-based side reactions in either electrolyte, improving efficient cyclability. ITO nanocrystal deterioration is significantly mitigated in cathodes using a CMC binder, and cells show good cycle life. In mixed DMSO-EMITFSI ionic-liquid electrolytes, Ru/RuOx/ITO materials in Li-O2 cells cycle very well and maintain a consistently very low charge overpotential of 0.5 - 0.8 V. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 January 2017.
All research outputs
#19,299,788
of 24,571,708 outputs
Outputs from ChemSusChem
#2,904
of 5,613 outputs
Outputs of similar age
#304,005
of 427,932 outputs
Outputs of similar age from ChemSusChem
#76
of 166 outputs
Altmetric has tracked 24,571,708 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,613 research outputs from this source. They receive a mean Attention Score of 3.4. This one is in the 40th percentile – i.e., 40% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 427,932 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 166 others from the same source and published within six weeks on either side of this one. This one is in the 45th percentile – i.e., 45% of its contemporaries scored the same or lower than it.
