Green Electrode Processing Enabled by Fluoro‐Free Multifunctional Binders for Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Solubilizing side chains plays crucial roles in ensuring the aqueous processability of conjugated polymers. However, they do not need to remain intact postprocessing. Through controlled thermal‐induced cleavage of these side chains, hierarchically ordered structures can be generated, enhancing electrochemical performance and facilitating their ...

Zinc‐Doping‐Induced Electronic States Modulation of Molybdenum Carbide: Expediting Rate‐Determining Steps of Sulfur Conversion in Lithium‐Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
Zn‐doped molybdenum carbide microflowers (Zn‐Mo2C) are exploited as a sulfur host for Li–S batteries. Zn doping elevates the d‐band center on Mo, enhancing LiPSs anchoring, weakening S─S/Li─S bonds, and reducing Li2S2→Li2S conversion energy barrier from 0.52 to 0.05 eV.

High‐Entropy Non‐Flammable Ionic Liquid/Dimethoxymethane Composite Electrolyte for High‐Performance Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
An ionic liquid/ether composite high‐entropy electrolyte with a unique Li+ coordination structure that leads to an upgraded solid‐electrolyte interphase and improved Li+ desolvation kinetics is developed. It exhibits high thermal stability, negligible corrosivity, and a large potential window, and is highly compatible with graphite, SiOx, and high ...
