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.

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 ...
