Abstract

Lithium-sulphur batteries are one very appealing power source with high energy density. But their practical use is still hindered by several issues including short lifespan, low efficiency and safety concern from the lithium anode. Polysulphide dissolution and insulating nature of sulphur are generally considered responsible for the capacity degradation. However, the detachment of discharge products, that is, highly polar lithium sulphides, from nonpolar carbon matrix (for example, graphene) has been rarely studied as one critical factor. Here we report the strongly covalent stabilization of sulphur and its discharge products on amino-functionalized reduced graphene oxide that enables stable capacity retention of 80% for 350 cycles with high capacities and excellent high-rate response up to 4 C. The present study demonstrates a feasible and effective strategy to solve the long-term cycling difficulty for lithium-sulphur batteries and also helps to understand the capacity decay mechanism involved.

  • In most cases, the lifespan of a Li-S cell is limited to few hundred cycles, especially at high discharge currents.

    “In most cases, the lifespan of a Li-S cell is limited to few hundred cycles, especially at high discharge currents [45,50].”

    From Parametric Study of a Lunar Base Power Systems (2021) · cites this paper as [50]

    The Abstract describes short lifespan as a barrier to Li–S batteries, and the Synthesis and characterizations section says most reported carbon–sulphur nanocomposites lose almost all capacity when cycled at similarly high rates. It does not establish a general limit of a few hundred cycles for most Li–S cells; its own EFG-S cell retains capacity through 350 cycles. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
