Influence of Preparation Conditions of Composite Positive Electrodes for Enhanced Reversible Capacity in All-Solid-State Na/S Batteries

Electrochemistry
Sodium-sulfur (Na/S) batteries are promising low-cost next-generation batteries. In particular, all-solid-state Na/S batteries are expected to demonstrate high capacity at room temperature because sulfur has a high theoretical capacity as a positive ...

Ether-compatible sulfurized polyacrylonitrile cathode with excellent performance enabled by fast kinetics via selenium doping

Nature Communications, 2019
Lithium sulfur batteries are promising for advanced energy storage, but polysulfide shuttling limits performance lifetime. Here the authors report selenium-doping in a sulfur-based cathode to prevent dissolution of polysulfide intermediates, leading to ...

Microbial diversity involved in iron and cryptic sulfur cycling in the ferruginous, low-sulfate waters of Lake Pavin.

PLoS ONE, 2019
Both iron- and sulfur- reducing bacteria strongly impact the mineralogy of iron, but their activity has long been thought to be spatially and temporally segregated based on the higher thermodynamic yields of iron over sulfate reduction.

Fe3O4-doped mesoporous carbon cathode with a plumber’s nightmare structure for high-performance Li-S batteries

Nature Communications
Shuttling of lithium polysulfides and slow redox kinetics seriously limit the rate and cycling performance of lithium-sulfur batteries. In this study, Fe3O4-dopped carbon cubosomes with a plumber’s nightmare structure (SP-Fe3O4-C) are prepared as sulfur ...

Joint Partial Least Squares Modeling of Experimental and Computational Data for Electrolyte Prescreening in Lithium–Sulfur Batteries

ChemElectroChem
Lithium–sulfur batteries have attracted great research interest due to the high theoretical capacity of sulfur of 1672 mAh g−1. However, they have various problems due to the shuttle current caused by molecular sulfur dissolving in the electrolyte. Hence,
