Heteroatom‐Synergistic Effect on Anchoring Polysulfides In Chalcone‐Linked Nanographene Covalent Organic Frameworks for High‐Performance Li─S Batteries

Advanced Science
Lithium‐sulfur (Li─S) batteries are an attractive option for future energy storage devices because they offer higher theoretical specific capacity, energy density, and cost‐effectiveness than commercial lithium‐ion batteries.

A Fluorine‐Free, Low Ion Pair Electrolyte for Transition Metal‐Free and Halogen‐Free Sodium Batteries

Advanced Energy Materials, EarlyView.
Fluorine‐containing electrolytes dominate modern rechargeable batteries, yet the fundamental design principles for fluorine‐free systems remain largely unexplored. We demonstrate that fluorine‐free electrolyte chemistry can simultaneously achieve long cycle life, fast charging, and stable interphase formation in sodium‐ion batteries.

Internal Electric Field‐Guided, Low‐Adsorption Ferroelectric Anode Protective Layers for Sustainable Suppression of Polysulfide Side Reactions in Lithium–Sulfur Batteries

Advanced Energy Materials, EarlyView.
A positively polarized ferroelectric β‐pvdf layer incorporating fluorinated boron nitride nanosheets (PPFBN) establishes a strong internal field that promotes Li+ transport toward the anode while suppressing the migration of polysulfide anions. In addition, its intrinsically low polysulfide affinity helps preserve protective‐layer functionality ...

Electrolyte Interfacial Reactivity Regulates Alloying Anode Pulverization

Advanced Energy Materials, EarlyView.
Electrolyte interfacial reactivity governs the degradation of micrometer‐sized alloying anodes by dictating grain refinement and SEI growth. A high‐reactivity ester‐based electrolyte drives pulverization into fine nanoparticles encapsulated by a thick SEI, forming dense electrodes, whereas a low‐reactivity ether‐based electrolyte enables porous ...

Decoupling Quasi‐Solid‐State Sulfur Conversion Mechanisms in Weakly Solvating and Locally High Concentration Electrolytes

Advanced Energy Materials, EarlyView.
Weakly solvating CME–TTE and localized high‐concentration G2–TTE electrolytes redirect lithium–sulfur chemistry toward quasi‐solid‐state conversion through distinct coordination environments. Molecular dynamics and multimodal electrochemical and spectroscopic measurements show that G2–TTE couples multidentate solvent coordination, anion participation ...
