In Situ Polysulfide Detection in Lithium Sulfur Cells

The Journal of Physical Chemistry Letters, 2018
Lithium sulfur batteries promise significant improvements in specific energy compared to Li-ion, but are limited by capacity fade upon cycling. Efforts to improve durability have focused on suppressing the solubility of intermediate polysulfides in the electrolyte.

Carbon Nitride Phosphorus as an Effective Lithium Polysulfide Adsorbent for Lithium–Sulfur Batteries

ACS Applied Materials & Interfaces, 2019
Lithium-sulfur (Li-S) batteries are attracting substantial attention because of their high-energy densities and potential applications in portable electronics. However, an intrinsic property of Li-S systems, that is, the solubility of lithium polysulfides (LiPSs), hinders the commercialization of Li-S batteries.

Hybrid Lithium–Sulfur Batteries with a Solid Electrolyte Membrane and Lithium Polysulfide Catholyte

ACS Applied Materials & Interfaces, 2015
Lithium-sulfur (Li-S) batteries are receiving great attention as the most promising next-generation power source with significantly high charge-storage capacity. However, the implementation of Li-S batteries is hampered by a critical challenge because of the soluble nature of the intermediate polysulfide species in the liquid electrolyte.

Stabilized Lithium–Metal Surface in a Polysulfide-Rich Environment of Lithium–Sulfur Batteries

The Journal of Physical Chemistry Letters, 2014
Lithium-metal anode degradation is one of the major challenges of lithium-sulfur (Li-S) batteries, hindering their practical utility as next-generation rechargeable battery chemistry. The polysulfide migration and shuttling associated with Li-S batteries can induce heterogeneities of the lithium-metal surface because it causes passivation by bulk ...
