Abstract

In Li-S batteries, it is important to ensure efficient reversible conversion of sulfur to lithium polysulfide (LiPS). Shuttling effects caused by LiPS dissolution can lead to reduced performance and cycle life. While carbons rely on physical trapping of polysulfides, polar oxide surfaces can chemically bind LiPS to improve the stability of sulfur cathodes. We show a simple synthetic method allowing high sulfur loading into mesoporous carbon, pre-loaded with spatially localized nanoparticles of several Magnéli phase titanium oxide, TinO2n-1. This material simultaneously suppresses polysulfide shuttling phenomena by chemically binding Li polysulfides onto several Magnéli phase surfaces in a single cathode, and ensures physical confinement of sulfur and LiPS. The synergy between chemical immobilization of significant quantities of LiPS at the surface of several TinO2n-1 phases, and physical entrapment ensures Coulombically efficient, long cycle life, high capacity and high rate cathode. These cathodes function efficiently at low electrolyte to sulfur (E/S) ratios to provide high gravimetric and volumetric capacities in comparison with highly porous carbon counterparts. Assembled coin cells have an initial discharge capacity of 1100 mA h g-1 at 0.1 C, and maintain a reversible capacity of 520 mA h g-1 at 0.2 C for more than 500 cycles. Even at 1C, the cell loses only 0.06% per cycle for 1000 cycles with Coulombic efficiency close to 99%.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. 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 30 May 2018.
All research outputs
#14,167,570
of 24,417,958 outputs
Outputs from ChemSusChem
#1,745
of 5,589 outputs
Outputs of similar age
#166,813
of 332,150 outputs
Outputs of similar age from ChemSusChem
#18
of 116 outputs
Altmetric has tracked 24,417,958 research outputs across all sources so far. This one is in the 41st percentile – i.e., 41% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,589 research outputs from this source. They receive a mean Attention Score of 3.4. This one has gotten more attention than average, scoring higher than 68% of its peers.
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 332,150 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 116 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 84% of its contemporaries.
