A three‐way electrolyte with ternary solvents for high‐energy‐density and long‐cycling lithium–sulfur pouch cells

SusMat
Lithium–sulfur (Li–S) batteries promise high‐energy‐density potential to exceed the commercialized lithium‐ion batteries but suffer from limited cycling lifespan due to the side reactions between lithium polysulfides (LiPSs) and Li metal anodes.

γ‐Valerolactone‐Based Anion‐Dominated Loose Solvation Electrolyte Enables Stable Lithium Metal Batteries from −60°C to 100°C

Advanced Science, EarlyView.
The precise regulation of GVL's solvation structure by two weak solvents with distinct functions promotes the formation of an anion‐dominated loose solvation structure, enabling the stable generation of EEI to protect the structural integrity of cathode materials and promote the uniform deposition of lithium.

Modeling Solid Electrolyte Interphase Formation and Morphology

, 2016
When a lithium ion battery is fully charged, the potential of its negative electrode is outside the stability window of the electrolyte, typically a mixture of organic solvents (ethylene carbonate, dimethyl carbonate) with a lithium salt. Consequently solvent molecules are reduced at the anode surface and reduction products form a film thus passivating

Microstructure‐Resolved Modeling to Predicting and Regulating Lithium Plating‐Stripping Dynamics on Graphite Electrodes

Advanced Science, EarlyView.
ABSTRACT The lithium plating reaction in graphite electrodes acts as a root cause for the accelerated degradation and the internal short circuits in lithium‐ion batteries. Here, an electrochemical model based on multi‐scale microstructural images was established to identify lithium plating‐stripping processes, thereby supporting the predictive outcomes

Multifunctional Phosphate Monomer Enabling LiNO3 Solvation and In Situ Formation of Flame‐Retardant Gel Polymer Electrolyte for High‐Voltage Lithium Metal Batteries

Advanced Science, EarlyView.
A phosphorus‐containing multifunctional monomer is successfully synthesized to simultaneously enable the dissolution of lithium nitrate in ester‐based electrolytes and in situ form a flame‐retardant gel polymer electrolyte (GPE). The formed GPE effectively stabilizes the structures of both the cathode and anode, thereby achieving superior long‐term ...

Interfacially Reinforced Crosslinked Binder with Structural Integrity for Stable Micro‐Sized Silicon Anodes in All‐solid‐state Batteries

Advanced Science, EarlyView.
ABSTRACT All‐solid‐state batteries (ASSBs) have attracted considerable attention as next‐generation energy storage systems owing to their high energy density and safety. However, their performance is critically limited by insufficient solid–solid interfacial contact and severe chemomechanical degradation, particularly for micro‐sized silicon (µSi ...
