Sentence examples for functional separator from inspiring English sources

In this work, a Nafion/super P-modified dual functional separator is designed to improve the long-term cycle stability and rate capability of the pure sulfur cathode.

We develop in this work a powerful functional separator to suppress the polysulfide shuttle by coating two-dimensional nitrogen-doped porous carbon nanosheets on one surface of a commercial polypropylene separator.

With such dual functional separator, a simple elemental sulfur cathode with 70% S content delivers a high initial discharge capacity of 1087 mAh g−1 at 0.1C and a long-term cyclability with only 0.22% capacity fade per cycle over 250 cycles at 0.5C.

To improve the performance of lithium-ion batteries, the functional separators were developed by coating water-based polyvinylidene fluoride (PVDF) powder particles solution using polyvinyl alcohol as the binder on both sides of a conventional polypropylene (PP) microporous membrane by means of simple dipping.

This functional coated separator is designed to localize the polysulfides on the cathode side and act as an upper current collector for further utilization of sulfur while alleviating the ion conductivity decrease induced by the dissolved polysulfides in the discharge and charge process.

In this review, the current trends, fundamental studies and developments for lithium-sulfur battery separators including some modified functional and novel battery separators with the customized structure designs are presented and reviewed.

Besides, the coulombic efficiency of the cell with functional carbon layer-coated separator rises from 80%too nearly 90% without the addition of LiNO3 additive, which indicates the reduction of shuttle effect.

The cell with functional carbon layer-coated separator can reach a high initial capacity of 1070 mAh g− 1 at the rate of 0.5 C, and maintain a high capacity retention ratio with the capacity of 778 mAh g− 1 after 100th charge/discharge cycle.

In polarization tests, the maximum power densities of new separators without functional groups were comparatively higher than those of Nafion and CMI.

Functional sections of a gas liquid separator utilize gravity settling, velocity separation by centrifugal force or impingement, and filtration.
