Formation of lithium polysulfides in aprotic media

Journal of Inorganic and Nuclear Chemistry, 1977
Abstract The formation of Li 2 S n in certain aprotic media can be accomplished either by electrochemical reduction of S 8 or by direct in situ reaction of S 8 with Li or Li 2 S. Polysulfide solubilities and spectra vary widely in different solvents as a result of solvent-solute interactions. A requirement for high polysulfide concentration is

Grafting and Depositing Lithium Polysulfides on Cathodes for Cycling Stability of Lithium–Sulfur Batteries

ACS Applied Materials & Interfaces, 2021
Based on dissolution/deposition chemistry, together with multielectron redox reactions, lithium-sulfur (Li-S) batteries have been demonstrated as a promising energy storage system. However, the diffusion of soluble lithium polysulfide intermediates (LiPSs) to bulk electrolyte results in the fast capacity fade of a Li-S cell.

Kinetics of Lithium-Polysulfide Flow Batteries

ECS Meeting Abstracts, 2014
We recently demonstrated that the high solubility of polysulfides in nonaqueous electrolytes can be exploited to make a high energy density lithium-sulfur flow battery with low storage cost1–3. Here we used a new approach, whereby percolating networks of nanoscale conductor particles (in this case carbon black) are incorporated within the electrode ...
