Janus‐Type Electrostatic Potential Gradient‐Activated Dynamic Zn2+‐Coordinating Nitrogen Sites in Molecularly Locked Nanocellulose Separators for Stable Zinc‐Ion Batteries

Advanced Science, EarlyView.
A multifunctional benzimidazole‐terminated CNF separator is constructed via a PEI‐mediated covalent locking strategy, generating dense zincophilic sites that accelerate Zn2+ transport and desolvation while enabling uniform Zn (002) deposition and suppressing side reactions.

The phase transfer effect of sulfur in lithium–sulfur batteries

RSC Advances, 2019
The insulating elemental sulfur in a Li–S battery could be reduced to high-grade polysulfides by low-grade polysulfides from the cathode, after which they could participate in the discharging process of the Li–S battery.

Strong affinity of polysulfide intermediates to multi-functional binder for practical application in lithium–sulfur batteries

, 2016
Binder, one of the most important battery components, plays a critical role in lithium–sulfur batteries. Poly(vinylidene difluoride) (PVDF), a commonly used binder in lithium–sulfur batteries, does not have a strong affinity to the intermediate ...

Sulfur‑Containing Additives for Enhanced Kinetics and Interfacial Stability of Phosphorus Anodes in Li‑Ion Batteries

Advanced Science, EarlyView.
A novel synergistic strategy by employing dual functional sulfur‐containing additives of lithium sulfide (Li2S) and its oxidation product lithium sulfate (Li2SO4) was proposed. Li2SO4 absorbs the solvent molecules to direct the formation of a uniform, Li2O‐rich, and adaptive interphase, which accommodates volume expansion and suppresses parasitic ...

Oxygen Vacancies on Layered Niobic Acid Weaken the Catalytic Conversion of Polysulfides in Lithium Sulfur Battery.

Angewandte Chemie, 2019
Oxygen vacancies are usually considered as beneficial in catalytic conversion of polysulfides in lithium sulfur battery. In this work, we demonstrated that the conversion of polysulfides was hindered by creating oxygen vacancies on ultrathin layered ...

Electrochemically Induced Interphase by Complex Hydride Anions in Argyrodite Solid Electrolytes for Stable Lithium Metal All‐Solid‐State Batteries

Advanced Science, EarlyView.
Complex hydride anion substitution in argyrodite electrolytes has attracted attention for improving interfacial stability, yet the influence of these anions at Li metal interfaces remains unclear. This work shows that electrochemically formed BH4−‐derived interphases enable stable high‐current full‐cell cycling.

Deciphering the Dynamic Balance Between Solvation Strength and Polysulfides Reaction Heterogeneity in Practical Lithium‐Sulfur Batteries

Advanced Science, EarlyView.
A weakly solvating fluorinated cosolvent (1200ET) enables precise solvation‐power regulation in Li–S batteries, decoupling interfacial stabilization from sulfur redox kinetics. This approach suppresses polysulfide dissolution while preserving reaction kinetics, leading to a stable Li metal interface and high‐energy multilayer pouch cells, revealing a ...
