Biocatalytic, Asymmetric Radical Hydrogenation of Unactivated Alkenes Open
Alkene hydrogenation is a cornerstone of chemical synthesis, yet enzymatic strategies remain limited to electron deficient substrates via hydride transfer. With heme enzymes, we unlock an unprecedented hydrogenation pathway – termed biocat…
Self-Discharge Behavior of Lithium-Sulfur Batteries at Different Electrolyte/Sulfur Ratios Open
The commercialization of lithium sulfur (Li-S) batteries is hindered by their poor cycling performance, including fast capacity fade, low Coulombic efficiency, and high self-discharge rate. The static electrochemical stability of Li-S batt…
Improvements to the Coulombic Efficiency of the Iron Electrode for an All-Iron Redox-Flow Battery Open
The all-iron redox flow battery is an attractive solution for large-scale energy storage because of the low cost and eco-friendliness of iron-based materials. A major challenge to realizing a continuously operable battery is the parasitic …
Influence of Pore Size on Discharge Capacity in Li-Air Batteries with Hierarchically Macroporous Carbon Nanotube Foams as Cathodes Open
The cathode microstructure of Li-air battery plays a significant role in Li2O2 storage and electron transfer. In this article, we report a tunable three-dimensional hierarchically macroporous carbon nanotube foam as the air cathode. Excell…
New Separators in Lithium/Sulfur Cells with High-Capacity Cathodes Open
Lithium-sulfur cells exhibit poor cycle life, due to the 'polysulfide shuttle' enabled by the dissolution of sulfur reduction products in organic electrolyte. Different strategies have been implemented to reduce the shuttle effects, includ…
Communication—Effect of Lithium Polysulfide Solubility on Capacity of Lithium-Sulfur Cells Open
Understanding the behavior of lithium (Li)-sulfur (S) cells under lithium polysulfide (LiPS)-saturated condition, especially determining whether LiPS solubility is an intrinsic limit for cell capacity, is of great interest for the developm…
