TL;DR: This work reports the synthesis of unique nanoscale spherical OMCs with extremely high bimodal porosities, investigated as a cathode material and sulfur host in Li–S batteries where they showed high initial discharge capacity and good cyclability without sacrificing rate capability.

TL;DR: A straightforward chemical approach is reported that probes the outcome of the superoxide O(2)(-), thought to initiate the electrochemical processes in the cell, and shows that this serves as a good measure of electrolyte and binder stability.

TL;DR: In this article, the role of surface adsorption vs pore absorption in Li-S cell capacity retention and cycle life was investigated using nanocrystalline and mesoporous titania additives as polysulfide reservoirs.

TL;DR: In this paper, a surface coating of SiO2 is applied to a Ni-rich LiNi0.6Co0.2Mn 0.2O2 cathode material in a bid to improve its electrochemical and thermal properties.

TL;DR: In this article, the authors investigated the chemical reactivity of polysulfides toward carbonate-based electrolytes through a simple probing experimental method and found that poly sulfides react with carbonate based electrolytes via a nucleophilic addition or substitution reaction leading to a sudden capacity fading of lithium sulfur cells by loss of active sulfur.
