Experimental study demonstrates tailored electrolyte solvation via hydrogen bonding in lithium metal batteries, indicating enhanced high-voltage stability.
Key Points
Tuning hydrogen bonding interactions alters electrolyte solvation structures, effectively promoting aggregate clusters that stabilize battery interfaces.
A non-flammable electrolyte achieves over 80% capacity retention and 99.8% average Coulombic efficiency across 230 cycles at a 4.4 V cutoff voltage.
Experimental evaluation paired dimethoxy-ethane with a fluorinated sulfonate diluent in cells using thin lithium foils and high-loading cathodes.
