STUDIES ON COLLOIDAL SULFUR-POLYSULFIDE MIXTURE

The Action of Colloidal Sulfur on Liver Oxidations

Colloidal sulfur has been used clinically for the production of fever in human beings, (see Shilvock (1) and Wailer and Allen (2) for the literature). One animal experiment has also been reported. Pi&y, Bonnamour, Milhaud, and Guiguonet (3) found that after injection of colloidal sulfur into rabbits, H2S was evident in the breath and that 0.01 gm. per kilo was a toxic dose. Rastelli and Casazza...

Studies on the Intrapulmonary Mixture

Free standing acetylene black mesh to capture dissolved polysulfide in lithium sulfur batteries.

Herein, we report a cheap and simple approach to solve the polysulfide dissolution problem in lithium sulfur batteries. It was interestingly revealed that a simple insertion of acetylene black mesh enabled us to obtain the capacity of 1491 mA h g(-1) at initial discharge and 1062 mA h g(-1) after 50 cycles.

Transport Properties of Polysulfide Species in Lithium–Sulfur Battery Electrolytes: Coupling of Experiment and Theory

A comprehensive experimental and theoretical analysis of the isothermal transport of species for the two model ternary-electrolytes with LiTFSI-Li2S4/dioxolane (DOL)-dimethoxyethane (DME) and LiTFSI-Li2S6/DOL-DME formulations is presented. An unambiguous picture of the polysulfide's mobility is set forth after a detailed investigation of the macroscopic transference number and diffusion coeffic...

A novel quasi-solid state electrolyte with highly effective polysulfide diffusion inhibition for lithium-sulfur batteries

Polymer solid state electrolytes are actively sought for their potential application in energy storage devices, particularly lithium metal rechargeable batteries. Herein, we report a polymer with high concentration salts as a quasi-solid state electrolyte used for lithium-sulfur cells, which shows an ionic conductivity of 1.6 mS cm(-1) at room temperature. The cycling performance of Li-S batter...
