Electric-Field-Oriented Interfacial Solvent Engineering Enables High-Voltage Ether Electrolytes for Ni-Rich Lithium-Ion Batteries

Abstract High-voltage operation of nickel-rich cathodes (>4.5 V) significantly boosts the energy density of lithium-ion batteries but triggers catastrophic oxidative decomposition of conventional ether electrolytes. Under high-potential electric fields, ether molecules in the ele...
