Improved Rate Performance of Lithium Sulfur Batteries by In-Situ Anchoring of Lithium Iodide in Carbon/Sulfur Cathode

Crystal Engineering of Molecular Solids as Temporary Adhesives

“…Selected compounds include iodine (IOD), octacyclic sulfur (OCS), hexachlorobenzene (HCB), naphthalene (NAP), (+)-camphor (CAM), dimethyl sulfone (DMS), (−)-menthol (MEN), and ( S )-ibuprofen (IBU). These molecules represent relevant case studies in pharmaceuticals, − organic electronics, , solid-state batteries, − and energetic materials. ,, Microcrystalline materials are extremely important in these fields, and consequently, extensive studies on the mechanical properties of polycrystalline materials are needed.…”

Ion transport mechanism in anhydrous lithium thiocyanate LiSCN Part I: ionic conductivity and defect chemistry

“…In terms of defect chemistry, some of the better understood binary lithium systems include LiH, 7 Li 3 N, 8,9 lithium chalcogenides 10,11 and lithium halides. [12][13][14] LiI has become an established additive for performance enhancement in various battery systems, [15][16][17][18][19] and a number of fundamental studies helped to understand its role as an additive. [20][21][22][23][24][25] Lithium thiocyanate (often referred to as a pseudo-halide) is chemically and structurally similar to lithium iodide, since they both have a large polarizable anion, 26,27 are hygroscopic and form hydrates.…”

Halogen-Doping Effect on the Delithiation and Charge Transfer of (Li2S)10 Cluster

“…An iodine-doped carbon/sulfur composite electrode exhibited good high-rate charge–discharge capability with a discharge capacity that exceeded by nearly 100 mAh/g that observed for its carbon sulfur analogue electrode. The superior features were ascribed to enhanced cathode electronic conductivity and to the dissolution of iodine species into the electrolyte which may improve ionic conductivity . Except for the iodine-doping effect on the cathode material discussed therein, no further analysis was made on the iodine interactions with sulfur compounds during cycling.…”

“…The superior features were ascribed to enhanced cathode electronic conductivity and to the dissolution of iodine species into the electrolyte which may improve ionic conductivity. 16 Except for the iodine-doping effect on the cathode material discussed therein, no further analysis was made on the iodine interactions with sulfur compounds during cycling. Furthermore, all-solid-state Li/S cells may prevent the migration of soluble polysulfides.…”
