Lithium–sulphur batteries with a microporous carbon paper as a bifunctional interlayer

Improved lithium-sulfur cells with a treated carbon paper interlayer.

A simple, low-cost modification of lithium-sulfur (Li-S) cells by placing a treated carbon paper between the sulfur electrode and the separator has been investigated to significantly improve the performance of Li-S cells. The treated carbon paper was prepared by an alcohol-alkaline/thermal treatment of a commercial Toray carbon paper, introducing hydroxyl functional groups and micro-cracks on t...

A hierarchical carbonized paper with controllable thickness as a modulable interlayer system for high performance Li-S batteries.

The carbonized Kimwipes® (CK) interlayer has been found to be a modulable, low-cost hierarchical interlayer for Li-S cells, leading to a high discharge capacity with superior cycling stability and rate performance. This new interlayer is designed to allow controllable thickness for analyzing the polysulfide interception mechanism within the interlayer architecture.

Copper-Stabilized Sulfur-Microporous Carbon Cathodes for Li–S Batteries

wileyonlinelibrary.com interact with two Li atoms per S atom, the S cathode can provide reversible high capacity of 1675 mAh g -1 at average potentials of 2.0 V, [ 1–3 ] which is 10× higher energy density than that of classical commercial LiCoO 2 cathode. Since the capacity of current LiCoO 2 -graphite Li-ion battery is controlled by LiCoO 2 cathode, replacement of expensive LiCoO 2 with cheap ...

Sulfur‐Doped Carbon with Enlarged Interlayer Distance as a High‐Performance Anode Material for Sodium‐Ion Batteries

S-doped carbon is investigated as a high-performance anode material for sodium-ion batteries. Due to the introduction of a high-content of S atoms, the as-obtained S-doped carbon shows an enlarged interlayer distance. As an anode, a high specific capacity of up to 303 mAh g-1 is achieved, even after 700 cycles at 0.5 A g-1.
